Replacing brake hoses on VAZ 2109 and 2110. step by step instructions

Replacing brake hoses on VAZ 2110, VAZ 2111, VAZ 2112

As a rule, brake hoses that are made of good rubber and are not kinked anywhere during installation will last quite a long time.
There are two reasons for their failure: 1) age and mileage; at high mileage, the hoses constantly move and are subject to greater pressure; 2) prolonged idleness of the car leads to hardening of the rubber and cracks. Note! You will need the following tools: a special wheel bleeder wrench (full name: brake pipe wrench), wrenches and screwdrivers.

Location of hoses

Front wheel drive vehicles use two brake hoses at the front and two at the rear. In the front part they are easy to find and convenient to change; just remove the wheels and they will appear before your eyes (shown in the top photo). And in the back you will need to crawl under the car. In this case, it is better to use the inspection hole and unscrew the fastening nuts (see bottom photo).

When to change?

Once a year, or just when you have to remove the front wheels, monitor the condition of the hoses. No one will tell you the specific mileage for replacement. The manufacturer actually recommends changing them after 125,000 km or 5 years of operation. At such values ​​it is necessary to do this, but the hoses can become unusable much faster. Therefore, keep an eye on them, and if you find any swelling, severe abrasions, cracks, or delamination of rubber, replace them immediately.

Reasons why you should change brake hoses

• Microcracks have formed in the bends of the hose, especially at the fastening points of the brake system element.
• Areas of abrasion appeared at the contact points between the hose and the suspension. In such a situation, you need to urgently decide how to replace brake hoses on a VAZ 2110, and you can’t do it without a specialist. His task is to establish the further operation of the system so that there are no abrasions and bald spots due to contact of parts.

• Brake fluid leaking from existing pipe connections is noticeable
• It is rare, but it is possible for stones, snow, dirt, ice to get into the brake system, which can cause malfunctions in its operation.
• Product error from the inside. You won't be able to tell by inspection, but there may be a detachment of the inside of the hose. With this option, the passage of brake fluid becomes more difficult and spontaneous blockage occurs. And this leads to disastrous results if you do not decide in time how to replace the brake hoses of the VAZ 2110

Cracks in hose bends Thus, it is recommended to carry out scheduled replacements of rubber parts when their service life is coming to an end or the machine is often used in extreme off-road conditions. A timely solution to the problem of how to change brake hoses on a VAZ 2110 will have a positive result than in cases of prolonging the problem, inflating the reasons for doing nothing.

Replacing a brake hose on a VAZ 2110

Brake hoses made of high-quality material usually have a long service life. Which VAZ 2110 brake hoses are better? Those that are made of high-quality rubber and preferably from a reputable manufacturer.

The reasons why this part fails are as follows:

1. The car is not new.
2. Its mileage is several tens of thousands of kilometers.
3. The car was idle for a long time.

What is needed to replace hoses

In order to change brake hoses on a VAZ 2110, you must have:

• wrench for brake pipe fittings;
• screwdriver;
• wrench.

Where is the part located?

If the car is front-wheel drive, then there will be 2 VAZ 2110 brake hoses located in front and behind it. To get to the front brake hoses, just remove the wheels. In order to find the rear brake hoses, you need to use the inspection hole and unscrew the fastening nuts.

Unscrew the loose nut

If the tube has never been unscrewed, then its edges are intact. However, the mileage is high, then there is a 95% chance that it has gone sour! I EXTREMELY DO NOT ADVISE you to climb and unscrew with a regular wrench, be it an open-end wrench or a socket wrench!

What you need to do initially:

• Clean the mounting area. Often there can be so much dirt that the nut is not visible at all.
• Treat the fastening area with liquids like WD-40 (they made a homemade one here), and wait 30 - 40 minutes
• We need a special wrench to remove the brake pipes. It has an extra bolt that fits very tightly around the edges of the nut.

Here the principle is simple, throw on the wrench, tighten the bolt on it and unscrew the nut. In 60-70% of cases everything works out quite quickly and easily. Watch the video

However, there are still 30 - 40% of cases. And here it is not always so simple.

Step-by-step instructions on how to replace brake hoses on a VAZ 2110

• One of the options for fixing the machine is used - a lift, an inspection hole, a jack.
• All necessary tools of suitable diameter and purpose are prepared.
• We fill the central cylinder (reservoir in the hood) with brake fluid up to the “max” mark, so that when removing the hose it will not all leak out. Otherwise, the system will need to be bled.
• We unscrew the upper fastenings of the hose and install a plug or cap to stop the brake fluid and not let it all out of the system.

Replacing the brake hose

• We take hold of the lower fastenings of the hose, release the hose from the shock absorber bracket, and unscrew the fitting from the working brake cylinder.
• We inspect the copper ring present in the fastening system. If it is not yet damaged, then we reuse it. But first, the ring should be thoroughly cleaned, and its seat itself should not be dirty.
• A new hose is installed, the same sequence is followed that was used when solving the problem of how to replace the brake hoses of a VAZ 2110.

  Unscrew the brake hose

Replacement and installation

We put the car on a jack or lift, remove the wheel, for ease of access we unscrew the wheel in the opposite direction from the side of the hose being replaced. Use a 15mm wrench to hold the edge of the inner part of the hoses and use a 10mm wrench to unscrew the fitting. We put a rubber cap on the tip of the tube, removed from the bleeder fitting on the working brake cylinder on the wheel, no matter how much brake fluid flows. We take out the hose from the bracket on the shock absorber and use a 15 wrench to unscrew the fitting from the working brake cylinder. If the copper ring remains on the cylinder, remove it and thoroughly clean the area of ​​dust and dirt before installation. If you don’t have a new copper ring, you can put in an old one, pre-treat it with sandpaper and level the surface. Installation is carried out in reverse order. It is important that after installation the new hose should not be twisted and when turning the wheel in any direction it should not touch the vehicle’s suspension elements.

Procedure for replacing the front brake cylinder on a VAZ 2110-2112

To show the entire repair process more clearly, watch the video I recorded for this topic:

Video instruction

The video was made using the example of a VAZ 2110 car and is equally suitable for both 2111 and 2112. The only way the car parts may differ externally is the brake discs: ventilated or not, as well as their sizes.

Photo report

First of all, we will need to remove the front wheel of the car, after first lifting the car with a jack. After this, using a hexagon, you need to unscrew the two bolts securing the caliper bracket.

Now you can remove the bracket and remove the pads:

Then you can rip off the brake hose with a wrench, but you don’t have to unscrew it completely.

Next, we unscrew two more bolts securing the cylinder to the caliper, having previously bent the two locking plates under them using a screwdriver.

How does CO work?

CO scheme

1. On the 8-valve injection VAZ 2110, the cooling system operates due to coolant forcedly circulating through it. When the engine heats up, excess pressure arises, which is released through the exhaust valve.
2. For the 16 valve injection VAZ 2110, the cooling system has an optimal operating temperature in the range of 90-95 degrees Celsius. And the valve is activated when pressure occurs with indicators from 1.2 to 1.4 kgf/cm2.
3. When the excess pressure is released, the engine returns to normal temperature and the intake valve is turned on. This happens cycle after cycle.
4. If the pressure balance is disturbed, overheating occurs, the consequences of which can be various types of breakdowns, including the need to completely replace the power unit.
5. Due to the operation of the thermostat and electric fan, the VAZ 2110 maintains the required constant operating temperature. There is a sensor on the cylinder head that transmits information about the current coolant temperature to the control unit.
6. A command is sent from the coolant temperature sensor to the cooling system, which begins to work in order to reduce engine heating.
7. If there is electronic injection in the car design, it also has a special sensor that sends a message to the electronic control unit about overheating of the power unit.
8. The pump supplies coolant, distributed by the thermostat.
9. When you turn on the engine, it needs to warm up to operating temperature. To do this, the thermostat directs the coolant through a small circuit, without including circulation through the radiator. The small circuit includes: Heater for warming up the interior;
10. Carburetor heating unit (naturally, only on carburetor VAZ 2110);
11. Heating of the throttle unit;
12. Intake manifold.

When the engine warms up to approximately 90 degrees Celsius, the thermostat sends some of the coolant to the radiator. When the engine overheating sensor is triggered, all the cooling liquid circulates through a large circuit. Article on the topic: Replacing the boot of the outer CV joint on a VAZ 2109 (Video)Source

Some tips on how to replace brake hoses on a VAZ 2110

Keys for brake pipes
Thus, the scheme for replacing brake hoses on a VAZ 2110 is carried out according to the standard scheme, taking into account safety precautions and the structure and contents of the vehicle. There is a difficulty that often arises - the brake hose fastenings cannot always be removed.

How do you deal with such a problem? Do you have experience in repair work and a win-win option for dismantling a brake hose? Share your experience.

Nuances

If both tubes are being replaced, then bleeding must be done sequentially - the front right wheel, then the front left one.

When replacing the rear brake hose of a VAZ 2110, the replacement principle is the same, except that on the rear hose on both sides there is a 10-point fitting and a 15-point key. Also, to replace the rear hose, you need a pit or a lift (theoretically, you can replace it on the ground, but this extremely inconvenient).

You can independently replace drum brake discs with disc brakes using this article: https://vazweb.ru/desyatka/tormoza/zadnie-diskovye-tormoza.html

When bleeding the entire brake system on a VAZ 2110, the algorithm is the same. But you will need to remove the rear wheels, and bleeding is carried out in the following order: rear left wheel, front right, rear right, front left.

Step-by-step instructions on how to replace brake hoses on a VAZ 2110

• One of the options for fixing the machine is used - a lift, an inspection hole, a jack.
• All necessary tools of suitable diameter and purpose are prepared.
• We fill the central cylinder (reservoir in the hood) with brake fluid up to the “max” mark, so that when removing the hose it will not all leak out. Otherwise, the system will need to be bled.
• We unscrew the upper fastenings of the hose and install a plug or cap to stop the brake fluid and not let it all out of the system.

Bleeding the brake circuit

Now it’s time to bleed the brake system of the VAZ 2110. If you only changed one hose, then you can bleed only one side on which you changed it. Add brake fluid to the level in the reservoir under the hood. We unscrew the fitting 8 on the working brake cylinder, on the wheel half a turn and put on the hose. We lower the second part of the hose into a bottle that should contain some brake fluid, the other end of the hose should be immersed in the liquid. To bleed, an assistant is needed; he sits in the driver's seat and presses the brake pedal several times until liquid comes out of the tube lowered into the brake fluid without air bubbles. When the fluid flows, you need to leave the brake pedal pressed, then tighten the fitting to 8. Release the pedal, clean the bleeding areas and connections from brake fluid and dirt, and press the brake pedal forcefully several times and check for brake fluid leaks.
