Self-installation of rear disc brakes on Lada Vesta - parts and work

When buying a car, car enthusiasts pay a lot of attention to the braking system. Since this system is responsible for the safety and comfort of driving. Ill-designed and ill-conceived brakes can cause traffic accidents and cause a lot of minor inconvenience to the car owner.

In its latest creation (Lada Vesta), AvtoVAZ showed a lot of innovations, starting from design, engine and ending with the chassis of the car. The brake system of the Lada Vesta was also not deprived of the attention of the developers and has undergone many changes and improvements.

Main differences between disc and drum

The braking mechanism consists of several parts and differs in two types of design.

The disk unit has an open design, allowing the device to operate for a long time without overheating. When you press the brake pedal, the brake pads are pressed against the disc mounted inside the wheel rim using a caliper. The degree of compression of the disc by the calipers is very high, which allows the car to brake more efficiently. As a result of heavy loads, the mechanism has a relatively short resource.

The drum mechanism has a closed cylindrical body, which prevents the entry of dirt and dust and has a long working life. The brake pads are pressed against the inner surface of the drum, causing the car to stop. The pressing force of the elements is comparatively lower than that of analogues with a disk, therefore such mechanisms are considered less effective.

The combination of front discs and rear drums is optimal in terms of efficiency and durability. This version of the Lada Vesta justifies itself with its reasonable price and reliability.

Work progress

For the right and left wheels the algorithm of actions is the same. Before you start replacing the rear brake pads of a Lada Vesta yourself, you need to drive the car onto an overpass, and then remove the sedan from the parking brake.

Next, the rear wheel is removed, and a support must be placed under the car.

To dismantle the drum, the pads must first be brought together. This is done with a regular screwdriver - it is inserted into the threaded holes in the drum itself, and it rotates a special ratcheting nut for automatically adjusting the gap between the surface of the brake drum and the pads. This will allow you to shorten the bar (spacer).

The photo below shows the entire mechanism with the drum removed. The nut rotates with the screwdriver up, in the direction indicated by the red arrow.

When this is done, you need to remove the drum bearing cap. It fits quite tightly, and therefore a chisel and a hammer are used for the work.

After the cap is removed, access to the hub bearing nut will open, which needs to be unscrewed using a 30 mm wrench and a socket.

After unscrewing the nut, you need to remove the brake drum (it is dismantled along with the bearing).

When the drum is removed, you must work carefully so as not to touch the ABS system sensor, marked with a red arrow in the figure.

Using a screwdriver, pry up and remove the spring (pressure) of the rear pad, as well as the support post. The support post of the second block is dismantled in the same way.

Then you need to remove the hook of the tension spring (lower) from engagement with the brake pad, after which the spring itself is removed.

The next step is to move the pad subassembly (rear) away from the brake shield

You need to work carefully, as there is a risk of damaging the brake cylinder seals.

The upper tension spring is removed in the same way.

When this is done, you can remove the spacer bar, and then the front block. You must first disconnect the end of the handbrake cable from the rear block, and then remove it too.

The mechanism for automatically adjusting the gap between the rear brake pads of the Lada Vesta is a spacer bar (composite).

When you press the brake pedal, the pads move apart and are pressed against the surface of the drum. This occurs due to the work of the wheel cylinder pistons. As for the protrusion of the lever, it moves in the opening between the teeth of the nut (ratchet).

As the pads wear, the nut rotates 1 tooth under the influence of the adjuster. This lengthens the bar (spacer) and moves the pads closer to the surface of the brake drum. Thanks to this complex, there is no need to adjust the handbrake.

The spacer bar itself has a complex design, and therefore if rust appears on it or if it is damaged, it is recommended to install a new part. If the condition is normal, it is better to wash the bar and lubricate it with a plastic compound.

Before starting assembly, you need to reduce the length of the bar as much as possible by screwing in its rear end.

Installation of the rear brake pads of the Lada Vesta is carried out in the reverse order.

Before installing the brake drum, its working area must be thoroughly cleaned with a wire brush. But when working, you must be extremely careful so as not to catch the ABS master ring.

The drum is secured with a hub bearing nut, which must be tightened to a force of 175 Nm. It is also strongly recommended to install a lock nut, this is especially true for the left wheel.

Self-replacement of the rear brake pads of a Lada Vesta on the second wheel is carried out in the same way.

When the work is completed, you need to check the brake fluid level in the reservoir. If it is insufficient, add liquid.

To adjust the brake pads, you need to press the brake pedal several times. Then, pressing the pedal, raise and lower the handbrake, while keeping the button on the handbrake constantly pressed. At this time, soft clicks will be heard from the rear wheels as the auto-adjustment mechanism operates. The handbrake needs to be raised and lowered until they stop coming.

If the need arises, you can additionally adjust the hand brake, which is done with a 10 key - there is a nut under the lever that should be tightened.

This completes the independent replacement of the rear brake pads of the Lada Vesta.

Rear brakes on Lada Vesta

Lada Vesta brakes The manufacturer installs rear disc brakes (RDB) only on sports versions of the Lada Vesta intended for racing.
This is due to the fact that sports cars are not equipped with an ABS safety system, and more efficient devices with discs can cope with skids. For all other versions, the car is equipped with a drum unit at the rear. Each car enthusiast can decide for himself whether to install drum or disc rear brakes on his car. He will not feel much difference from replacing the elements.

Purchase and installation of disc brakes

You can buy Lada Vesta rear disc brakes at any AvtoVAZ specialized store or on online store websites. The average price for a complete set of spare parts is 15 or 18 thousand rubles, depending on the presence of an ABS sensor. The brake pads should be changed after 30-45 thousand kilometers.

In order to install a motor instead of drums, you must follow a certain procedure:

• remove the wheel from the car beam;
• unscrew the nut from the hub;
• unscrew the bearing and remove the drum;
• install the disc and caliper on the beam hub, tighten the bearing;
• tighten the bearing nut.

After installing all braking mechanisms, it is necessary to check the brake fluid level in the hydraulic drive reservoir. If it deviates from the norm, you need to add fluid.

Replacing drum brake pads

Before starting work, the handbrake lever should be completely lowered down. The installation process has its own procedure:

• remove the rear wheel;
• using a slotted screwdriver, unscrew the ratchet nut that adjusts the length of the spacer bar;
• remove the block and replace it with a new one;
• install the drum back;
• tighten the bearing nut.

Durability

Drum brakes are more durable than disc brakes. Their safety is almost unaffected by different weather conditions: rain, temperature changes, etc. Nor can they become icy in winter.

VAZ regulations: pads in drums must be changed every 60 thousand km, and inspection is carried out every 15 thousand. The pads on the discs are changed as needed, and according to reviews, VAZ pads “live” 30-45 thousand km. By the way, they would live less on the rear axle.

Vesta drums are equipped with TRW pads from the factory - there are no complaints about VAZ here. At the same time, everyone knows that drum brakes are less effective at speed, and they do not withstand prolonged loads (they overheat). Let the reader draw his own conclusion.

Additional security systems on Lada Vesta

In addition to the main braking mechanism, designed to control the car by the driver pressing the pedal or using the handbrake, the AvtoVAZ car has a number of adaptive electronic devices:

• ABS – prevents wheel locking during emergency braking;
• HSA – assistance when starting off and driving on an incline;
• TCS is a traction control device that helps overcome light off-road conditions without slipping, distributing torque to the wheel depending on its load;
• ESC - exchange rate stability system controls the behavior of the car in a skid, thanks to which the car maintains the specified trajectory;
• EBD is a braking force distribution device that allows you to apply different forces and influence the speed of stopping.

Considering all these innovations on the Lada Vesta, paired with good braking elements, they can prevent any emergency situation on the road related to the stability and control of the car.

Rear wheel disc brakes (RDB) are installed on Lada Vesta from the factory, but not on all trim levels. Tuning enthusiasts who have rear drum brakes have a choice: buy a HA kit for Vesta from third-party manufacturers or modify the brakes according to the factory version. In this article we will tell you what is required to install a standard HTD kit.

One of the owners of Lada Vesta Exclusive managed to find out from an AvtoVAZ employee what was needed to replace Vesta’s drum brakes with disc brakes. According to him:

• There is no need to change the beam.
• There is no need to flash the ABS block.

The second photo shows that between the beam and the axle there is a spacer (factory) to which the boot is attached. In the factory version, the disc and hub are made separately and this is a huge advantage; there is no need to constantly change bearings with each disc replacement.

Description of innovations

On the Lada Vesta, the brakes received a number of new functions. The new car has such useful systems as ABS BAS in all trim levels. The front pads have several technological differences compared to the rear ones. Lada Vesta is equipped with more expensive and high-quality brake system components compared to previous cars produced by AvtoVAZ. More advanced mechanisms and technologies are used.

The front wheels of the Lada Vesta are equipped with disc braking mechanisms. The rear wheels of the car are equipped with drum systems. In addition to the mechanisms and technologies listed above, Lada Vesta has:

• EBD (electronic brake force distribution system);
• HSA (a system that helps with hill climbs);
• ESC (the car is also equipped with a stability control system);
• TCS (traction control system, helps get out of difficult situations on the road).

Many technical innovations make Lada Vesta a pioneer for the Russian automobile industry in various aspects. Innovations in the braking system create all the conditions for a safer and more comfortable ride.

The best manufacturers, brands, analogues

The working brake system in a car is for the safety of the driver, passengers, and other road users. The basis of the design is:

During systematic use, parts wear out, linings wear out, and braking efficiency decreases. The process of preventing the brake circuit is simple, but requires attentiveness on the part of the technician.

Impressions from the “Russian girl”

Vesta definitely left a pleasant impression. For the money, this is a well-built, spacious and well-thought-out car with a lot of goodies and good handling.

It costs an average of 563 thousand rubles. No problem, according to statistics from avtocod.ru, every fourth car is sold. Every third person is involved in an accident, every fourth is a lien or a repair bill. Vestas with unpaid fines, traffic police restrictions and after taxis are less common.

If you take it, keep in mind that its shortcomings are common to its entire class. Still, this is not a Golf, and it is unreasonable to demand anything more from it.

Step-by-step instructions for replacing the front brake disc on a Lada Vesta car

Reviews

Inspection of the body from the Lada Vesta interior

After examining the front panel in the showroom, the car service specialists stated that, judging by the joints and the quality of the materials, it would begin to creak within six months. Experts have noticed that car window seals are not of very high quality; therefore, after some time of using electric windows, scratches from accumulated dust and dirt will appear on the windows.

Replacing headlight bulbs will be convenient. Hands can easily reach the lamps in the engine compartment. But replacing taillight bulbs will be complicated by the fact that it will be necessary to fold back the trunk lining. It is also difficult to find the lamp socket from the taillight. In addition, it is worth noting the presence of plugs in the front fender liners, which make access to the fog lamps easier.

In the table below we show the cost of all repair work on a Lada Vesta car, which was announced by specialists from a private independent car service center.

We replace the pads of a Lada Vesta car in case of maximum permissible wear of their linings - the minimum thickness of the pad, including its base, must be at least 6 mm.

We carry out the work on a flat area, inspection ditch or overpass.

If the fluid level in the hydraulic brake reservoir is at the MAX mark, then before installing new pads, use a syringe or rubber bulb to pump out some of the fluid from the reservoir. This operation must be performed so that when the piston is pressed into the wheel cylinder of the brake mechanism while installing new pads, fluid does not flow out from under the reservoir cap.

Using a metal brush, we clean the spring brackets and pad seats in their guide from dirt and corrosion.

To replace the cover of the upper guide pin, you need to unscrew the bolt of the upper fastening of the bracket to the pin and remove the bracket from the pad guide. Before installing the pin, put a little grease into the hole in the pad guide...

We similarly replace the pads on the other side of the car.

During operation, the surface of the brake disc becomes uneven, as a result of which the contact area of ​​the new, not yet worn-in pads with the disc decreases

Therefore, during the first 100 km of driving after replacing the pads, until the new pads have broken in, be careful, as the car’s braking distance may increase, the pads may get hotter than usual, up to the appearance of light smoke and smell, especially in hot weather.. https: //www.youtube.com/embed/zAOeWh3Efdc. https://www.youtube.com/embed/zAOeWh3Efdc
