Hand (parking) brake system on VAZ 2110

The parking (or hand) brake is designed to keep the car from moving on an uneven surface. When the handbrake lever is fixed in the upward position, the cable is tensioned, going to the equalizer, which in turn distributes force to the two rear wheels through two cables. At the moment when the cable is tensioned, the spacers in the drums of the rear wheels move the blocks in different directions, which fixes the wheels, and accordingly the car, in a stationary state.

Like any part of a car, the parking brake tends to fail. If such a situation occurs with your car, then it is necessary to carry out repairs as quickly as possible. Replacing a VAZ 2110 hand brake with your own hands is not a difficult procedure if you have the tools and appropriate skills. Let's look at each element separately.

Signs of a malfunction of the VAZ 2110 hand brake

There are a number of signs that indicate a malfunction of the parking brake system. We list the main ones:

  • When the handbrake is pulled on, the rear wheels spin and the car rolls down the hill. The cable is probably loose and needs to be tightened.
  • When the handbrake is weakened, the rear wheels jam. This indicates frozen (in winter) or worn out pads. There is also a high probability of a faulty return spring.
  • When driving, you can hear squeaks from the rear wheel drums. As in the previous case, the pads jam.
  • One of the wheels is blocked and does not rotate (goes skidding). In this case, a spring malfunction is excluded - the problem is inside the drum in one of the wheels.

In most cases, it is enough to adjust the brakes, since the cable tends to stretch and sag. It is also not uncommon to encounter a malfunction inside the drums themselves due to their vulnerability to external factors.

How do they work?

The operation scheme is trivial and simple - there is a handle that connects to a cable, which, in turn, is in a special braid (that is, the cable flows through it). Next, this wire hooks onto a special adjusting screw (it can be tightened and unscrewed), which connects to a rail, along the edges of which there are two wires going to the two rear wheels. These cables (going to the wheels) are in a mesh with a special bracket; it is he who unfastens the blocks and blocks the drums.

Simply put, when we move the lever up (raise the handbrake), the cable stretches and pulls two separate cables towards the wheels. Inside the drums, brackets push apart the rear blocks, which block the wheels.

Adjusting the hand brake VAZ 2110

The first thing you will need to do when a malfunction is detected is to adjust the tension of the handbrake cables. To do this, drive the car onto a pit or lift and follow these steps:

  • Place wheel chocks under the wheels and loosen the lever by lowering it down.
  • Loosen the locking nut with one wrench, and use the second wrench to tighten the adjusting nut. Tighten until the cable stops sagging.
  • Check by pulling the lever up - the number of clicks until it is fully tensioned should be in the range from 2 to 4. If this is the case, leave the lever in this position.
  • Tighten the locking nut, holding the thread from turning.
  • Loosen the handbrake lever and check the rotation of the rear wheels - they should spin without resistance.

The manufacturer recommends tightening the handbrake every 30,000 km.

Replacing the hand brake lever on a VAZ 2110

If adjusting the handbrake does not help, then it is necessary to replace one of the elements of the handbrake. And one of the possible faults is a broken lever. To replace it, you will need a standard set of tools and 15-20 minutes of time. Place the car over the hole and secure it with wheel chocks.

The first thing to do is disassemble the plastic panel between the seats. Then you need to loosen the cable tension and remove the rod axis located on the lower part of the lever (from the bottom side). After this, unscrew the 4 bolts securing the lever bracket to the car body (10mm wrench). It is very important not to damage the ground wire, which is attached to the body along with the lever bracket.

Replacing the hand brake rod of a VAZ 2110

The parking brake linkage often requires replacement because it is used in conditions of high humidity and dirt. The most common reason for replacing it is a rusty thread, which makes it impossible to adjust the handbrake. To perform the work, you need to lift the car on a lift or drive it into a pit. Next, follow these steps:

  • Lower the handbrake lever to the down position.
  • Unscrew the adjusting and locking nuts from the lever rod.
  • Remove the lever axis by pulling out the pin with pliers.
  • Remove the lever rod from the cable equalizer housing.

Installation is in the reverse order. After installation, adjust the parking brake tension.

We adjust the parking brake system.

Adjustment sequence:

  1. loosen the locknut of the tensioning device;
  2. by rotating the adjusting nut, tighten the cable;
  3. the full stroke of the parking brake drive lever should be 3-5 teeth per sector;
  4. when the lever is completely released, the wheels should rotate freely, without jamming; tighten the locknut.

A properly adjusted parking brake system should hold the vehicle on a 23% grade.

Replacing hand brake cables on a VAZ 2110

Cables tend to stretch, unravel, rust and get stuck in places where they come into contact with other elements. If such a situation occurs, then they need to be replaced. Replacing the hand brake cable of a VAZ 2110 is a procedure that will take you several hours of time, since to complete the work you need to remove the rear wheels and disassemble the drums. So let's get started:

  • Before installation, lubricate the new cables with transmission or any other oil.
  • Unscrew the adjusting and locking nuts, thereby disconnecting the distributor.
  • Remove the rear wheels, then remove the brake drums.
  • Remove the cables from the brake housing.

Install the parking brake cables in reverse order.

Replacement

The process is longer than adjustment, but not much more difficult. Therefore, you can cope with the task in your own garage with a lift or inspection hole.

There is one important condition - you will need an assistant. His task will be to pull the cable tightly, which will allow the equalizer to be installed correctly.

The sequence of work to replace the cable is as follows:

  1. Lower the handbrake lever as far as possible;
  2. Remove the brake disc from the wheel where the element is being replaced;
  3. Remove the muffler from the suspension cushions and the resonator from the rear suspension;
  4. Lower the exhaust system down;
  5. Remove the adjusting nut and locknut;
  6. Remove the equalizer;
  7. Now remove the cable ends from the equalizer;
  8. Remove the tip of the equalizer shell from the bracket, which is located on the car body;
  9. Bend back the brackets that secure the cable;
  10. Remove the rear brake pad and remove the cable end from the lever;
  11. Slightly loosen the nut that secures the cable holder to the rear axle;
  12. Remove the cable from the holder, then from the bracket, and then pull it out through the brake spike;
  13. Place a new cable in its new location and perform the assembly procedure, following the reverse order of the indicated processes;
  14. Make sure that the cables in the bracket are positioned crosswise;
  15. After completing the installation of the new element, adjust the handbrake.

As you can see, the task does have certain nuances, but it is not difficult at all if you have some experience and rely on the VAZ 2110 operating manual. As a rule, everything is spelled out there.

It wouldn’t hurt to supplement your skills and knowledge with video tutorials or consultation with a friend from a service station. But if you are not confident in your own abilities, you should not risk replacing the handbrake cable yourself. It is better to spend more money, but entrust the work to specialists.

Purpose and location of the parking brake

The location of the handbrake is known to every VAZ 2110 driver - there is a lever installed between the front row seats, when pressed, braking occurs. The metal cable is a mechanical drive in this unit. By lowering the lever, the driver provides tension on the cable, which presses the rear brake pads to the wheel discs. Breakage of the lever is extremely rare, since the main load falls on the metal cable, as a result, after some time it loses the required tension.

The operation and maintenance manual for the VAZ 2110 states that at least once every six months it is necessary to carry out diagnostics of the brake system, including the parking brake. The traffic regulations have requirements for this unit - it must hold the car at a slope of 25 degrees. If the metal cable is not damaged, and the adjustment does not bring results, then the problem is in the rear brakes - this requires a full diagnosis from specialists.

What is needed to adjust the handbrake

To adjust the parking brake, you will need one of the following tools:

In the absence of all these conditions, which any ordinary driver is unlikely to be able to provide, you can get by with support “goats”, which are installed under the rear of the body after it has been raised with a jack. It is also worth considering the presence of two “13” keys and pliers in the set.

Where to start adjusting

VAZ 2110 handbrake does not work

The parking brake adjustment process is as follows:

  • the car is placed on an overpass (or a ditch, or generally raised with a jack);
  • the position of the brake lever is checked - it should be the lowest;
  • Using the first key, the lock nut is loosened, while at the same time holding the adjusting nut with the second key.
  • The adjusting nut is tightened until the handbrake cable is tensioned.

Note. When tightening the adjusting nut, the rod must be held with pliers.

VAZ 2110 tighten the handbrake

  • Now you should make sure that the full stroke of the lever is from 2 to 4 clicks;
  • After the stroke has been checked, the equalizer locknut should be tightened while holding the adjusting nut with a wrench.
  • The handbrake lever goes down, after which the rear wheels are turned by hand. Their rotation should occur evenly and without jamming.

Note. If the handbrake drive cable cannot be tensioned during the adjustment process, this part should be replaced.

How to tighten the handbrake on a Prior? The auto industry breaks down as always - Fix the Car!

If the handbrake on a VAZ-2112 becomes difficult to hold, then you should not change it immediately, since the cable can be adjusted. If the mileage on the car is high, the rear pads on the car may wear out. This may reduce the effectiveness of the handbrake and the entire braking system. In this case, the handbrake cable will need to be tightened.

Handbrake diagram for VAZ-2112

For clarity, here is a diagram of a hand brake

1 - button that fixes the handbrake lever; 2 — hand brake lever; 3 — protective cover; 4 — handbrake rod; 5 — cable equalizer; 6 — adjusting nut; 7 - lock nut; 8 - cable; 9 — protective sheath of the cable.

In this scheme we need element number 6. It is he, and only him!

What is required for adjustment?

In order to adjust the handbrake you need a platform or lift. If there are no such devices, then you can simply hang the rear wheels on the “goats”. They can be installed under the car using a jack. It’s also worth taking two “13” keys and pliers.

Start:

  1. The car is installed on an overpass or “goats”. Hanging out your butt
  2. The lever position is set to the lowest possible position. We put the handbrake at the very bottom. Do not pay attention to the scuffs of the console; we conducted an experiment with non-standard armrests. The iron fastenings of the armrest are visible. The photo shows the editorial car
  3. Use a wrench to loosen the locknut. Adjusting nut
  4. The second wrench holds the adjusting nut.
  5. The adjusting nut should be tightened until the cable is tensioned. It must be remembered that the rod should be held with pliers when tensioning the cable. Tighten the adjusting nut
  6. After this, you should make sure that the full stroke of the handbrake lever is no more than 4 and no less than 2 clicks.
  7. When the stroke check is completed, the locknut is tightened. The adjustment is held with another key.
  8. If necessary, change the mechanism to a new one. Everything is rusty, we changed the adjustment mechanism
  9. After releasing the adjusted lever down, you should spin the rear wheels. When the lever is in its lowest position, the wheels should spin freely.

If you cannot tighten the cable, then it should be replaced with a new one.

Adjusting the handbrake after tensioning

After adjusting the brakes, you need to check them again. To do this, the car should be placed on a road with a slope of at least 23%. The car should be in neutral gear in this area and with the handbrake pulled up. If the handbrake brakes hold the car in this area, then the handbrake is adjusted correctly.

What to do when adjustment does not work

There are also cases when the above actions are not enough to adjust the handbrake. This can happen, for example, when the handbrake cable is broken. This happens on the VAZ-2112, although rarely. In such situations, the cable must be replaced. The cable also needs to be replaced when:

  1. The tips are loose.
  2. The cable itself begins to stretch, which will lead to its breakage during operation. HAIKU! The old cable is very worn out! For comparison, old and new handbrake cables
  3. Physical wear (scuffs and cracks) of the handbrake cables. Heavy wear on the handbrake cable
  4. It is quite difficult for the cable to move in the casing even after lubrication.

This replacement procedure does not require contacting a service station. Although this will require some time and skills from the driver, such work can be done independently.

It should also be remembered that when replacing the cable, certain conditions must be observed. To do this, the driver will need an assistant who will pull the cable.

Why do you tighten the handbrake?

The cable acts here as a drive. If the driver pulls the handbrake lever, then at the same time he uses the cable, which spreads the pads in the rear wheel.

If the handbrake is faulty, you just need to tighten the cable or replace it with a new one. On a VAZ-2112 it’s quite easy to do this with your own hands.

Need for adjustment

You can determine that the parking brake needs adjustment when checking. It is recommended to do it every 30,000 kilometers. This procedure should be done even if the handbrake seems to be working well.

The device must also be checked in cases where it does not work. For example, a car moves when the brake lever is applied.

Cause of cable failure

Replacing the handbrake lever of a VAZ 2110

The main reason why the handbrake rod breaks, naturally, is the service life of this cable. The fact is that when used, the cable is subjected to constant loads from the forces actuating the handbrake and due to the fact that it is located under the body of the vases, constantly interacting with high humidity, while experiencing a lack of lubrication. As a result, the steel threads that make up the cable simply fray. Also, the reason for the breakdown of the VAZ 2110 hand brake cable may be that during operation, wear of the drums and brake linings of the right and left wheels occurs in an uneven order, causing the corresponding cables begin to lengthen by different amounts and the handbrake simply stops working over time.

Replacing the handbrake lever of a VAZ 2110

The parking brake can also receive mechanical damage after emergency braking of the car, when the driver activates all brake systems. Due to the weakening of the cable tips and its difficult movement in the sheath, breakage is also possible, which leads to the need to replace the cable. In any case, regardless of the reason for the need to replace the parking brake cable, every car owner will sooner or later have to face this problem.

VAZ 2110: replacing the handbrake cable yourself

The parking or hand brake of a vehicle is designed for emergency braking in an emergency situation. The main purpose is when parking for more than 6 minutes with the engine turned off, the parking brake is activated by a lever. It is located between the front seats of the vehicle. On a VAZ 2110, replacing the handbrake cable is sometimes caused by the need to take care of safety. Replacing the VAZ 2110 parking brake cable can be done on your own.

What is a handbrake for?

Replacing the handbrake cable on a VAZ 2110

According to the current Traffic Rules, the handbrake of a VAZ must hold the vehicle on a slope of up to 25%. When lifting the lever up, it should produce from 2 to 8 clicks. If the car has been in operation for more than three years, then it is necessary to check the parking brake system. You can go to a car service center, where qualified specialists will carry out high-quality diagnostics. You also need to do this process yourself. Having stopped the car on a level surface, the lever rises all the way up with a smooth movement. In this case, the clicks are counted; there should be no more than 8 of them. When leaving the cabin, you need to apply force from behind, trying to move the car. If it rolls, then you will have to adjust the handbrake. After tightening the cable, the result is the same, which means that only one thing remains - to completely check the condition of the rear brake system.

Checking the rear brake system

Replacing parking brake cables on a VAZ 2110

  • The car is installed on an overpass or in a garage in an inspection hole. Anti-roll bars are placed under the front wheels. The rear part is raised with jacks and reliable supports are installed. The lever goes all the way down.
  • The rear drums are removed and checked for wear. They will not allow a lot of wear and tear. The rear brake pads are checked; their thickness should be more than 2/3 of the new pads. The condition of the cable is inspected from below; it should not have any abrasions or broken strands.

Diagnostics and testing of the handbrake on a VAZ-2110

According to the regulations, adjustment of the hand brake is carried out once every 30 thousand km.

However, there are situations when adjustments cannot save the situation. In cases where the handbrake cable is stretched to the limit or when the rear pads and brake drum are worn out, adjustment will not give any results.

The design of the parking brake system of the VAZ-2110 car.

Terms and Conditions

The factory says that under normal operating conditions, the handbrake lever should make 2-4 clicks before the rear wheels are completely locked.

It’s easy to check - find a slope of about 20-25% , tighten the handbrake all the way ( there should be no more than 7-8 clicks ), put the car in neutral. If a car with a normal load holds well on a slope, the system is in good working order, and you can continue to operate. Otherwise, adjustment is necessary.

The exception is those cases when the handbrake cable is torn, soured in the casings or stretched . Then, first, we buy a new cable, and after replacing it and diagnosing the condition of the brake drums and rear pads, we will make adjustments.

If the adjustment does not help

There are not many cases when adjusting the parking brake did not have any effect. However, this is no reason to despair.

It is possible that the handbrake cable has broken. This is a rare occurrence, but all options need to be considered. Especially if your VAZ 2110 is not new. By the way, on newer models the cable also breaks if the car is used very intensively. The braking system is simply not designed for such loads.


Device diagram

There are several situations in which it is necessary to replace the parking brake cable:

  • The cable broke;
  • The tips gave way;
  • The cable threads have stretches, which over time can turn into a full-fledged rupture;
  • The cable is difficult to move inside the sheath even after abundant lubrication.

Useful information about the VAZ 2110 car: 8 valve injector

Hello, in this article you will learn how to replace the handbrake cable on a VAZ 2110, 2111, 2112. If you notice that the handbrake no longer holds the car on a slight slope of the road and adjusting the handbrake did not solve this problem, then it is necessary to replace the parking brake cable. The average price is from 200 rubles and above. From the tools we need a wrench for 10 and two wrenches for 13.

So, let's begin. First of all, we remove the car from the handbrake. Then remove the brake drum and unhook the cable from the brake shoe.

In order to get to the cable fastenings, it is necessary to remove the resonator and muffler from the rubber cushions

The next step is to unscrew the lock nut (1) and the adjusting nut (2) of the hand brake and remove the equalizer (4) from the rod (3). Unhook the end of the cable

Then unscrew the cable fastenings from the brackets from the car body

Now you need to remove the rear brake pad and unhook the end of the cable from the brake shield and remove it

We install the cable in the reverse order of removal, it is necessary to take into account the location of the cables - crosswise. After that, we adjust the cable tension.

Malfunctions and their symptoms

Determining that a cable needs adjustment or replacement is quite simple. Signs of a faulty mechanism appear as follows:

  • The handbrake is pressed effortlessly - the cable is loose, you need to tighten it.
  • The mechanism does not respond to pressing the lever - the drive is torn or flew out, or the reason may be the wear of the rear pads.
  • If the handbrake is stuck, the drive is damaged and needs to be replaced.

Important! The parking brake needs to be checked at least once every 30 thousand kilometers. The handbrake must always be applied.

Having taken out the main element, you can visually determine its condition. Replacement is required in the following cases:

  • Up to 2% are damaged or torn.
  • The cable moves with difficulty even after applying lubricant.
  • The drive tips have grooves.

Is adjustment necessary?

First you need to determine whether the adjustment will really solve the problem of the handbrake malfunction.


Adjusting the parking brake

To do this, a small test is carried out. Moreover, it is recommended to do a similar procedure after every 30 thousand kilometers, even if you are sure that the parking brake works well.

Drive your vehicle to an area where there is a slight slope. Place the car on it, turn on the handbrake and shift to neutral. If the car starts to roll down, everything is obvious - the handbrake needs repair.

Pulling up the handbrake

It is likely that you just need to tighten the parking brake on the VAZ 2110 to fix the problem.

  1. Drive to the inspection hole, from where it is most convenient to make adjustments. Another option is a lift. You'll find something here. This way you can easily get to the necessary nodes.
  2. Make sure the brake lever is in its lowest position.
  3. Take two keys. You will loosen the lock nut first and tighten the adjusting nut second.
  4. Tighten the adjustment nut until the cable is properly tensioned.
  5. It is strongly recommended to hold the rod when tightening the adjustment nut with pliers.
  6. Now make sure that the lever makes full travel in 2-4 clicks, no more.
  7. If after checking everything turned out to be good and the working stroke is correct, tighten the equalizer locknut while holding the adjustment nut with a second wrench.
  8. Release the handbrake lever down and turn the rear wheels by hand. Rotation should occur evenly without any jamming.
  9. But if the adjustment did not allow the cable to be tensioned, then the element must be replaced.

The handbrake doesn't hold

The article and the presented videos are devoted to adjusting the handbrake, but in some cases the handbrake does not hold due to worn brake pads or the absence of a cable. If the handbrake has not worked since you purchased the vehicle, before making adjustments, make sure that the cable has not been broken due to normal wear or loose fitting.

Drum brakes

The easiest way to adjust the handbrake is on a drum brake system. Schematic representation of the VAZ 2113-15 hand brake device.

Raising the handbrake lever moves the rod (5), from which cable contours go to each of the wheels under the bottom of the car. Passing through the brake shield, the cables are connected to the levers of the manual drive of the pads. When the handbrake is raised, the cable acts on the lever (13), the upper part of which is fixed to the axis (12). As a result, the force created by the lever is uniformly transmitted through the expansion bar to the brake pads, pressing them against the drums.

In some types of construction, a combination of rods is used instead of cables, but it is the device described above that can be found on all modern cars with rear drum brakes.

How to tighten the cable

The essence of the adjustment is to move the cable equalizer along the rod towards the front of the car. Depending on the design of the car, the adjustment mechanism can be located in the cabin or under the bottom, as is the case with VAZ 2115,2114,2113,2199,2109,2108, Opel Astra F and many other cars.

To access the adjustment mechanism located in the cabin, there is often a special hatch in the central tunnel. In our case, the process is described and shown in the video using the example of a car, where the adjustment is carried out under the bottom, so the car must first be driven onto an overpass or inspection hole. Instructions that will allow you to tighten the cable if the handbrake does not hold.

  1. Use a wire brush to clean the threads of the adjusting rod.
  2. Loosen the locknut. In order to stiffen the structure when unscrewing and tightening it back after adjustment, you will need 2 keys - with one you need to hold the adjusting nut while unscrewing, and with the second you need to unscrew the lock nut.
  3. Move the position of the adjusting nut by tightening it the required number of turns.
  4. Once adjustment is complete, tighten the lock nut until it is pressed firmly against the adjusting nut.

What degree of tension is considered correct?

In the case of technical inspection, which is not carried out on civilian vehicles in the Russian Federation, the effectiveness of the hand brake is checked in two ways:

  • a vehicle with a full curb weight must be securely secured with a handbrake on a slope of 16º or 25º, depending on current requirements;
  • The effect of the handbrake is checked on special drums. In this case, not only the braking force is measured, but also the uniformity of its distribution between the rear wheels.

Traditional methods

When adjusting the parking brake yourself, you can estimate the tension of the handbrake cable in two ways:

  • by the number of clicks. In this case, it is worth looking for information on a specific car model, since, for example, for a Daewoo Matiz the norm will be 7 clicks, and for a VAZ 2106 – 2-4 clicks. The only drawback of the adjustment is that sometimes after replacing the brake drums, pads, and observing the average value for the number of clicks, even with the handbrake lowered, the brake pads can be pressed too hard against the drums. Therefore, after servicing the rear drum brakes, the degree of tension should differ from the average requirements, but after grinding in, the handbrake will need to be tightened;
  • according to the degree of pressing of the friction linings. To adjust the handbrake, the rear wheels will need to be lifted. The cable must be tightened to such a state that when the parking brake lever is lowered, the shoes barely touch the brake drums. When rotated by hand, the wheel should rotate quite freely, but at the same time a barely noticeable sound will be felt from the friction linings pressed against the drums (if the pads are worn unevenly, then a characteristic sound during rotation will be in a certain position of the wheel). With this adjustment, after covering 100-200 km, the friction linings will wear off a little, and the gap will become close to ideal.

Aspects indicating the need to adjust the handbrake

There are several ways that will help any car owner, without exception, to help with the question of whether it is advisable to adjust the handbrake. It is worth noting that there is no need to check the handbrake every day; it is important to pay attention to this detail every 30 thousand kilometers.

To find out whether the handbrake needs to be adjusted, you need to park your car on a slight slope, then leave the car on the handbrake and put the gear in neutral. If the vehicle slowly but surely begins to move down an incline, then the vehicle's parking brake may not be working properly.

Of course, this problem can be solved by replacing the VAZ-2110 handbrake rod, however, as practice shows, it is quite enough to make a very simple adjustment of this part.

  • The travel of a properly adjusted handbrake lever should not exceed 8 clicks. The optimal lever stroke is 6-7 clicks (this number varies depending on the car model; details for a specific VAZ model can be found in the operating instructions supplied with the car).
  • After installing the new cable, the rear wheels of the car should be jacked up and try to spin them by hand. Rotation must be free.
  • Now the brakes should be checked while driving. You need to drive 30-40 meters, then slow down using the parking brake. After braking, you need to get out of the car and touch the rear brake drum. It should not be hot, its temperature should not exceed the ambient temperature. If the drum gets so hot that it burns your hand, this means that the brake cable is too tight and should be loosened.
  • To loosen the cable, you should put the car back on the inspection hole, unscrew the lock nut on the outer tip with a 13mm wrench, and then loosen the main fastening nut. After this, the locknut is tightened again.
  • If the brake cable is too slack, it needs to be tightened. All steps are listed above, with one exception: the main nut on the tip should be tightened, not unscrewed.
  • To independently check the reliability of the parking brake, you should find a slope with a ratio of 1:5 (that is, 1 meter high and 5 meters long), drive the car onto it, turn off the engine, put the car on the parking brake and squeeze the clutch. After these actions, the machine should remain in place and not roll downhill. If the car does roll, you should tighten the brake cable a little more.

As you can see from our article, there is nothing complicated about replacing a brake cable, and even a novice car enthusiast can do this task. The main thing you should pay attention to in this case is compliance with safety regulations. When changing a cable, it is very easy to get injured or get a chemical burn, so it is better not to carry out this operation alone, but to work together with an experienced auto mechanic.
