Brake pads are an extremely important element of the braking system of the car, and the safety of both the car and the participants largely depends on their serviceability. traffic. Therefore, you need to constantly monitor the condition of the brake pads and replace them in a timely manner. This operation is not very complicated, so it is easy to carry out on your own if you have all the necessary tools without going to an expensive service station. As an example, consider the process of replacing pads on a VAZ 2110.

When to change pads

The brake pads of a VAZ 2110 car, if you do not delve into their design, consist of a friction lining and a special frame. Friction linings carry out braking and, just by the material from which they are made, they distinguish between these linings. This material (for the friction lining) is based on a special reinforcing component, which determines such design parameters as strength, stability, heat resistance and reliability of the braking qualities of the system.

New brake pads for VAZ 2110

Like any part, VAZ 2110 brake pads have their own service life, which is usually 30,000–50,000 km of a car’s run or reaching a friction lining thickness of 1.5 mm. (that is, they practically grind to zero, but at the same time, most often, when braking, piercing unpleasant sounds occur from under the wheels). For brake pads less than 1.5 mm thick. there is an excessive stroke of the pistons of the brake cylinder, which leads to its leakage.

The brake pads should also be replaced if:

  • friction linings are covered with an oily substance (oily);
  • the mobility of the overlays on the base was detected;
  • deep chips, grooves or cracks appeared on the surface of the friction linings.

It is also necessary to monitor the wear of the brake discs, which should be replaced when they reach a thickness of 17.8 mm. (for ventilated discs) or 10.8 mm. (for non-ventilated).

Which one to choose for replacement

The quality of the brake pads also affects the quality of braking and comfort when decelerating the car (no whistle, rattle). It is also necessary to consider the following when choosing a consumable:

  • Poor-quality pad material can be the main cause of creaking, as well as accelerated pad failure;
  • When buying, choose front brake pads with manufacturer's catalog number 21100-3501080-00;
  • Identical brake pads can behave differently with different brake discs, which greatly complicates the choice;
  • To do right choice when buying brake pads, you need to read reviews in car magazines, directly at points of sale, among friends.

IN Lately for the VAZ 2110, brake discs from Ferodo, ATE, Allied Nippon and Lucas are very popular.

How to withdraw

For this operation, it is necessary to prepare key No. 17, key No. 13 and pliers. We pre-jack up, remove the wheel, as when replacing it, and prepare a set of new brake pads designed for the VAZ 2110. Next:

  1. With the help of pliers, we bend the edge of the locking plate at the lower bolt on the wheel cylinder.

    Using pliers, bend the edge of the locking plate

  2. We take the key No. 13 and unscrew this lower bolt, but at the same time we hold the guide pin with the open-end wrench No. 17.

    We take the key number 13 and unscrew the bottom bolt

  3. Remove the bottom bolt and plate.

How to change front pads

  1. To install new brake pads, follow the above steps in reverse order. However, it is necessary not to forget to clean the seats from dirt, install the inner block, and transfer the bracket to the working position. Then we move the bracket with a screwdriver, resting it on the brake disc and sinking the piston with a screwdriver, which is inserted through the hole for the caliper.

    Using a gas wrench, press the piston into the brake cylinder

  2. If the new front pads are equipped with a wear sensor, then you need to connect it. We cut the wire responsible for pad wear.

  4. We take out the rest of the wire.

    Pull out the rest of the wire.

  5. We connect a new block with a new connector.

  6. After changing the brake pads, we pump the brakes - we press the brake pedal several times. This is done so that the pistons take their working position. Now check the brake fluid level under the hood. If it is minimal, add brake fluid. By the way, be careful, it is very toxic and can corrode rubber hoses and even paintwork!

It happens that the piston of the brake disc does not return to its original position. In this case, the brake bleeder should be unscrewed, which will facilitate the return of the piston. If this does not help, then remove the entire brake mechanism of this wheel to squeeze the piston in a yew and replace the seals. It is very important not to hit the piston when performing these works, as this can lead to distortion and scratches on the cylinder mirror.

How to change rear pads

  1. To replace the rear brake pads, we put the car on a lift, a viewing hole or just on a flat area, remove the wheel and lower the hand brake.
    Next, take the key number 12 and unscrew the two guide pins. You may have to use a seven-millimeter hexagon instead of key number 12.

    With a key number 12, unscrew the pins

  2. We strike with a hammer on the brake drum, turning it evenly. It is better to strike not directly on the drum, but through a wooden block or other hard object.

Video: Replacing the rear brake pads

It is recommended that with the wheel already removed, also inspect other parts of the brake system, as well as the suspension. Brake hoses must be intact, absolutely no cracks. Brake pads need to be changed only as a set (in pairs), otherwise the car will pull to the side when braking.

In previous articles, we have already learned how often to change brakes, when to replace, how to check wear:

In this article, we will go directly to replacing the front brake pads.

So, for work we need:

  • spray can;
  • wd-40 - we use it wherever it is impossible to unscrew the fasteners;
  • wrenches, box wrenches on "13";
  • new set of brake pads;
  • car jack;
  • flat screwdriver.

Before starting work, be sure to put your car on a flat surface, put in first gear, put on the handbrake. On both sides, put “shoes” (halves of bricks) under the rear wheels.

How to remove front brake pads?


  1. The very first thing to do is to loosen the wheel bolts on both sides, mind you: just LOOSEN!
  2. We install the jack under the car and raise the front wheel (place the jack on a flat surface).
  3. We completely unscrew the front wheel mount, remove the wheel.
  4. For convenience, we completely turn the steering wheel towards the disassembled wheel: if the left wheel is removed, then we unscrew the steering wheel completely to the left side.
  5. Pay attention to the figure: we take the key to 13 and unscrew this bolt, having previously bent (straightened) the counter-key. Do not lose the bolts, as will have to be installed back (It is worth noting that some manufacturers of brake pads put new fasteners in the box).
  6. We open a barrel of brake fluid, using a syringe, pour a little liquid into a jar in order to leave a reserve in case the liquid rises up the level. If, however, the liquid is at the min level, which is very dangerous, then nothing needs to be drained.
  7. We move the caliper (under the number 1 on the diagram) and get access to the pads.
  8. Next, we need to push the brake piston back into the cylinder. Because as the pads wear, the piston is forced further and further out of the cylinder. To do this, we find an inspection hole (indicated by the number "A" in the diagram). Next, take a flat screwdriver and thread it into the inspection hole between the block and the brake piston. And we begin to move the piston back into the cylinder. Don't use too much force to move the piston, you need a steady amount of force and time.
  9. We remove the fasteners of the brake hose, so as not to interfere.
  10. We move the caliper.
  11. We remove the brake pads.


How to install front brake pads?

  1. We take new brake pads and put them tightly in the grooves to the brake disc: we rest the pads with the antennae against the stops and press them against the disc (look at the picture).
  2. We close the caliper.
  3. We twist our bolt and do not forget to bend the control washer.
  4. Put the brake line back in place.
  5. We put the wheel and twist the fasteners crosswise.
  6. Add brake fluid to the barrel and close it.

On a note!

IN modern cars the matter is a little more complicated. The electronic brake distribution system (EDC) checks (using speed sensors) whether more brake force needs to be applied to the front or rear axle. Depending on which one has the best grip on this moment.

The ABS system, if one of the wheels slips, reduces the pressure of the brake fluid directed to its clip and activates impulse braking, preventing it from blocking.


Important!

Brake pads are the executive element of the brake system. If they are heavily used, braking will be ineffective.

How are brake pads arranged?

The basis of their design is a steel base (tablet), on which the manufacturer's marking, date of manufacture and other information are placed.

The second main element is the friction layer, that is, the working surface. Between the friction layer and the steel base there is a bonding layer and an insulating damping layer.


On a note!

As mentioned earlier, brake pads are also responsible for driving comfort. Therefore, in blocks designed for premium cars, additional damping elements are used.

This can be a damping film between the base of the block and the clamp, or a damping sheet (metal layer covered with rubber and silicone paper) used between the block and the clamp, or optionally between the friction material and the base of the block.


The third solution (not excluding the use of the previous ones) is a forklift attached to the base of the block, the task of which is to change the vibration frequency of the block during braking, which as a result calms its work.

The friction material of the pad consists of a mixture of metals (eg steel wool), fillers (eg iron oxide), release agents (eg coke powder) and organic materials (eg resins). Proportions are the secret of every manufacturer.


What is the durability of brake pads?

It depends on a number of factors such as:

  • The quality of the friction material from which the block is made.
  • How does the cooperation between brake disc and brake pad work.
  • The condition of the brake disc - for example, a warped disc will cause rapid damage to the block.
  • The way you drive. Sporty, aggressive driving, frequent mountain driving, frequent city driving - all this causes accelerated wear of the blocks.

You can assume that good, branded brake pads, when correct use, can withstand up to 70,000 km, of course. The cheapest can withstand from 20 to 30 thousand. km, of course.

On a note!

Symptoms of damaged brake pads are, of course, poor braking performance and all sorts of noise during movement and braking. This can be caused by wear sensors on the acoustic linings (metal inserts), which are designed to warn of insufficient thickness of the friction layer.


Premium cars use electronic brake pad thickness sensors. They warn you that the block is too small with the help of a backlight on the dashboard. The blocks are replaced when the friction lining thickness is less than 3 mm. Also, when the shell is cracked, chipped, or unevenly worn (for example, beveled on one side).

How to replace brake pads in a car?

Blocks are always replaced in pairs on one axle (front or rear) or on both axles of the vehicle. They are selected for a specific model, year of manufacture and engine version of the car.

On a note!

Quality pads extend the life of your brake discs. The cheapest ones, if their shell is hard, can cut them effectively.

  • Repair begins with loosening the bolts securing the rims to the hubs.
  • The car must be immobilized and raised. In the workshop - on the lift. At home - raise the chassis with a jack (place it in the place intended for support - it is marked on it).
  • The wheel(s) must be unscrewed and removed.
  • The next step is to unscrew the brake calipers. Unscrewing the bolts can be inconvenient due to their formwork. Special tools and penetrating lubricants are required to facilitate screw disassembly.

After disassembling the clamp, it must not be “hung” on the brake line so as not to damage the cable.


This is a good opportunity to check the condition of the flexible brake hoses.

  • The next step in the repair is to check the condition of the brake pistons. Seals most often break in them, and the metal pistons themselves can corrode. The reason lies in untimely replacement brake fluid.
  • The next step is to insert the pistons and install the brake pads into the clamps and assemble them. In premium cars, sensors must be installed to measure the thickness of the blocks.
  • The pad guides should be lubricated with high temperature copper grease and the terminal slots should be cleaned. The terminals themselves must be cleaned of corrosion, for example with a wire brush.

They can also be thoroughly cleaned, degreased and painted. This good protection from rust.

  • The next steps are to install the clamp, screw in the wheel and lower the car.
  • After replacing all brake pads, check the brake fluid level as well as the system.

After assembling the blocks, it is worth remembering that the first few hundred kilometers should not be braked quickly, because the blocks must be correctly positioned.


On a note!

Any deviations from the standard, such as vehicle pull during braking, poor braking performance or noise, are the result of improper assembly of the blocks. You must repeat this as soon as possible.

Replacing brake pads - do it yourself or in a workshop?

How much does it cost to replace brake pads? The average price in the workshop is 2000-3000 thousand rubles. In professional workshops, such an exchange lasts up to an hour. At the request of the client, mechanics can independently order and purchase brake pads for a specific car model.


Why choose a replacement workshop?

  • The cost of the service is low and the repair time is short.
  • Brake pads are a guarantee of safe driving, so improper assembly plays a role in the safety of you and others.
  • During replacement, the mechanic can check the condition of the remaining parts of the brake system and, if necessary, repair or replace them. This mainly applies to flexible brake hoses and pistons.
  • The use of specialized workshop tools and equipment (e.g. an elevator) facilitates and speeds up repairs.

What are the risks of changing brake pads yourself?

  • This is especially inconvenient without a lift.
  • You need to have a range of tools.
  • The hobbyist must devote a lot of time to replacing and may run into problems that can outgrow his skills.
  • Incorrect assembly of the blocks will cause the car to steer during braking, or it will be due to poor braking performance, resulting in a decrease in safety.
  • In some vehicle models, changing blocks requires the vehicle to be connected to a diagnostic computer so that the brake piston can be retracted.

Brake pads ensure safe driving. Details are located on a disk (drum). During braking, the pressure exerted on the pedal is transferred to the pads. Spare parts are pressed against the drum. Wheel rotation stops.

What are the brake pads?

There are rear and front brake pads.

Brake pad wear depends on several factors:

  • driving style;
  • Weather;
  • The condition of the road surface;
  • Pad quality.

How to replace rear brake pads?

The rear brake pads need to be replaced regularly. The wear of the part is indicated by an unpleasant whistle and rattle that occurs when the machine stops. It is recommended to change the pads after 30-40 thousand kilometers, depending on the operating conditions.

Replacing the front brake pads

It is best to buy original spare parts. IN without fail change the brake pads on both wheels of the same axle at once. Otherwise, due to uneven wear, the controllability of the car will decrease. After installing the parts on the drum for the first couple of hundred kilometers, sudden braking should be avoided.

To replace the brake pads, the wheels must be removed from the vehicle. Then the pins are knocked out of the caliper and the springs are released. Remove inner and outer pads. Thoroughly clean the guides and drum from dirt and dust. Install new pads. Check the brake fluid level. The replacement algorithm may differ depending on the car model.

How to replace front brake pads?

Front brake pads wear twice as fast as rear ones. To replace parts, you must first remove the wheels. Then it is necessary to bend the edges of the locking plate, which prevents the bolts from unwinding. Next, unscrew the connection. Raise the caliper and remove the pads from the guide. Before installing the parts, move the piston as far as possible into the cylinder. The scheme for replacing brake pads is almost the same for all car brands, but there may be slight differences.

With excessive wear, removing parts can be a serious problem. You will need tools and equipment for dismantling. High-quality and quick replacement of brake pads can only be performed by specialists. We recommend that you use the services service center, which always has original auto parts for chevrolet, mazda, toyota or other car brands in which they specialize. The specialists of the service center will quickly and efficiently replace worn-out brake pads of any type in the shortest possible time.

Any car owner can change the front brake pads on their own in the garage or in field conditions. This step-by-step instruction will help to change the brake pads correctly and without errors. Even those who first decided to wave the pads with their own hands will be surprised how simple and quick the procedure is.

If you service the car yourself, then as a result you get satisfaction, and of course, saving money.

How often should the brake pad thickness and brake fluid level be checked? The answer is obvious - regularly. If the pads are worn out thinner than two mm, then in no case postpone the replacement - this is fraught with jamming of the caliper and expensive repairs.

Keep in mind - the front pads wear out faster. On disc brakes, it is very easy to check the thickness of the brake lining visually, so be sure to check it often.

What tools do you need to replace brake pads with your own hands.

As you can see, the set of tools you need is minimal.

Attention! Before you start replacing your brake pads, make sure the new pads fit your car, in other words, make sure you buy the right pads.

Step 1. We open access to the brake mechanism.

Place the car on a firm, level surface, place stops under the wheels so that it does not accidentally roll. It can be either special "shoes" or ordinary bricks or bars.

Before lifting the car with a jack, we tear off the wheel bolts. Then we raise the required side with a jack, completely unscrew the bolts and remove the wheel. Now access to the caliper is open.

Step 2 Remove the old pads.

The caliper is put on the brake disc like a clamp, and its task is to compress the brake disc with pads using hydraulic pressure. This is how braking occurs.

Calipers are usually one-piece or two-piece construction, fastened with two or four bolts with inside wheels to the caliper brackets.

Spray the caliper bolts with WD-40 to make them easier to remove. let the grease work for 5-10 minutes, then you can unscrew the caliper guides.

If there are fixing brackets, then you need to remove them with a small screwdriver. Many vehicles have pad wear sensors, so carefully disconnect the connectors.

Check caliper pressure. We take a large screwdriver and wring out a little pad, crushing the cylinder. Thus, the old pads will be easy to remove.

The caliper of the car at rest should move slightly back and forth. If not, the caliper is under pressure and may come off when the bolts are removed. Check if there are any shims or wear washers installed between the caliper mounting bolts and the mounting surface. If there is, then remove and inspect them, if necessary, replace with new ones.

Brake caliper guide bolts

Many vehicles use a two-piece sliding caliper that only requires the removal of two guides with 12-14mm sockets. You won't need to remove the entire caliper.

Do-it-yourself front brake pad replacement

Now we remove the caliper or set it aside if the guides were unscrewed only on one side.

Carefully hang the caliper from a wire or rope to the wheel or strut spring.

Do-it-yourself front brake pad replacement

Attention! The caliper will still be connected to the brake line, so secure it so it doesn't pinch or pull on the brake hose.

We take out the brake pads from the brackets. We clean the seats of the pads with a metal brush or a screwdriver.

Do-it-yourself front brake pad replacement

Be sure to check the guide bolts - the anthers must be intact, and the guides themselves should walk easily and smoothly in the grooves.

Attention! Each time the brake pads are replaced, the caliper guides must be cleaned and lubricated. This procedure will not take much time, but will extend the service life and increase the reliability of the brakes.

Use a special high temperature grease to lubricate the guides. Litol, in the old fashioned way, does not need to be used. Some pad manufacturers can find such a lubricant complete with new pads.

Step 3. Installing new brake pads.

All preparatory operations are completed - proceed to the assembly.

The first step is to press the brake cylinder completely. Compress the caliper cylinder to the brake caliper piston. Changing the brake pads with your own hands, and if still in the field, you can use a wheelbrace or a clamp to compress the caliper piston. You can also make a special tool with your own hands, use a large bolt and an old block for this. There are a lot of options, the main thing is to take into account the principle of operation of the original tool and use your ingenuity.

how to push in a brake caliper piston without a special tool in the field

Attention! Some analog pads may differ slightly in shape. For example, the lugs of the pads may be longer than the seats in the brake calipers, and the part does not fit into the grooves. In this case, do not panic, but check whether the shape and design of the shoe matches the rest of the parameters.
Yes, corresponds - we grind off the extra protrusions to the size of the old block.
No, does not correspond - there are significant differences - it is necessary to select other pads. Do not try to make the right pads out of the wrong ones, because of this, the brakes may jam or work poorly.

We insert new pads and put on the caliper. We treat the threads with copper grease to prevent corrosion.

We assemble the caliper, as we disassembled, put on the wheel.

Important! Before you go on a trip - after replacing the pads you need brakes. Press the pedal all the way. Pull up and slow down. And so repeat a couple of times. Everything is fine? Repeat braking at higher speed. Make sure there is no grinding or other discomfort.

What causes brakes to stick?

  1. Worn or dirty brake caliper piston. It is necessary to monitor the condition of the piston mirror and the integrity of the anthers and cuffs.
  2. Distorted brake pad. Check the correct installation and fit of the part.
  3. Wear, contamination, corrosion of caliper guides. lubricate and change the anthers or the guides themselves.
