Proper pads are a guarantee not only for your safety, but also for the safety of other road users. Excessive wear on these components increases the risk of losing control of the vehicle and causing an accident. In order not to become a victim of your own negligence, it is necessary to systematically check the condition of the pads and change them in time. By the way, for this it is not at all necessary to contact a car service.

In this article we will look at how to independently replace the front and rear brake pads of the VAZ-2110. But first, let's look at the signs of their malfunction, diagnostic methods and choosing the right model.

Design and principle of operation of the front wheel brakes

The front wheels of the "tens" have a disc design. It is based on:

• brake disc;
• caliper;
• working brake cylinder with piston;
• two pads;
• fasteners.

When we press the brake pedal, the fluid acts on the piston of the working cylinder and moves the caliper. The pads placed inside it are pressed against the brake disc, causing the hub to stop rotating.

How do you know it's time to change your front pads

Each detail of any mechanism has its resource, after which it must be changed. The front pads of the VAZ-2110 are no exception. Their resource, according to the car manufacturer, is 10 thousand kilometers. But this is only under the condition of their normal operation. Often they fail much earlier. They can report their failure:

• a warning light on the dashboard;
• decrease in braking efficiency and "wobble" of the steering wheel;
• creaking, grinding, crunching when braking.

Someone will probably be surprised, but the front brake pads of the VAZ-2110 have a wear sensor in their design. When they are erased more than the norm, a signal lamp in the form of a wheel lights up on the dashboard. This is the first indication that it's time to change the pads.

If you notice during braking that the car starts to lose control and during this, extraneous sounds are heard from the front wheels, this is also a reason to diagnose the brake mechanism.

How to check pads

Checking pads is to determine the thickness of their pads. To do this, of course, you will need to dismantle the wheel and disassemble the caliper or drum. Measurements are made with a caliper or a regular ruler. The thickness of the overlays must be at least 1.5 mm. If the result of your measurements is close to this value, hurry up to replace the pads.

Which brake pads for VAZ-2110 to choose

Only the right choice of parts of the brake system will allow you to feel confident on the road. And don't skimp here. As for the manufacturer, as usual, preference should be given to the original. Front brake pads VAZ-2110 go under catalog numbers 2110-3501080, 2110-3501080-82 or 2110-3501089. Such parts are inexpensive - about 300 rubles. You can choose pads and well-known global manufacturers of auto parts. They will cost more (up to 1000 rubles), but their quality is noticeably better.

In no case should you buy cheap analogues from Asia. Not only do they wear out twice as fast, but their construction is quite fragile.

Important: pads, both front and rear, are changed only in pairs and always on both wheels of the axle! That is why branded parts are sold exclusively in a set of four.

Required tools and tools

So, if you have already purchased replacement parts, make sure that you have the necessary tools and tools at hand. Among them:

• jack;
• balloon wrench;
• liquid against rust;
• 20cc medical syringe;
• keys for 13 and 17;
• flathead screwdriver;
• pliers;
• hammer and chisel;
• pipe (gas) wrench.

Changing the front pads

Replacing the front brake pads on the VAZ-2110 is as follows:

1. We put the car on a flat area. Fixing the rear wheels.
2. Turn off the wheel bolts, jack up the body and dismantle the wheel. We turn the steering wheel in the direction of the disassembled wheel until it stops.
3. Inspecting the brake mechanism for mechanical damage.
4. Determine the amount of brake fluid in the reservoir. If it is full, we select the liquid (30-50 ml) with a syringe.
5. Knock down the retaining ring from the lower caliper mounting bolt. To do this, use a skein and a chisel.
6. Using the 13 key, unscrew the lower caliper bolt. Hold the guide pin with a key at 17. If necessary, use an anti-rust liquid.
7. Remove the bolt and remove the caliper with the cylinder.
8. Open the caliper and remove the VAZ-2110 brake pads from it.
9. A wear sensor is installed on the rear (inner) pad. Using pliers, we bite off the wire going to it. After that, disconnect the sensor connector.
10. Install new pads in the caliper. Be careful and don't get confused. Inside there is a block on which the sensor is installed.
11. If the cylinder piston interferes with installation, "drown" its projections with a pipe wrench.
12. After installing the pads, connect the sensor to the wiring harness.
13. Assembly in reverse order.
14. Following this algorithm, we replace the pads on the other wheel.

After completing the work, do not forget to add brake fluid to the reservoir. Also check if the lamp on the dashboard is on.

Rear brake design

The brakes of the rear wheels of the "tens" have a drum design. Includes:

• working brake cylinder;
• two pads;
• parking brake actuator;
• fasteners.

The principle of operation of the rear brake is as follows. When you press the pedal, the brake fluid acts on the pistons of the working cylinder. They move out and spread the pads to the sides. Their pads rest against the working surface of the drum, causing it to stop rotating.

The handbrake is actuated by a cable and rod. We pull the handle, the cable acts on the traction, it spreads the pads.

What you need to replace the rear pads

First you need to purchase the pads themselves. When choosing them, follow the advice given above. Domestic auto parts manufacturers sell VAZ-2110 rear brake pads under original numbers 21080-3502090, 21080-3502090-00, 21080-3502090-55, 21080-3502090-90, 2108-3502090, 2108-3502090-80. It will not be superfluous to purchase a set of springs: tightening and guides.

From the tools you will need:

• jack;
• balloon wrench;
• hammer;
• wood spacer;
• wrench 8;
• two wrenches for 13;
• liquid against rust;
• long nose pliers.

Before you change the brake pads on the VAZ-2110, do not be too lazy to release the manual cablebrakes. Without this, given that they do not have wear, you are unlikely to be able to install them in the drum. The cable is loosened in the inspection hole with two open-end wrenches at 13.

Change the rear pads on the "top ten"

The process for replacing the rear pads is as follows:

1. We put the car on a flat area, immobilize the front wheels. We turn off the bolts of the desired wheel.
2. Jack up the body, unscrew the bolts completely, dismantle the wheel.
3. Using an 8 wrench, unscrew the guide pins on the brake drum (2 pcs.).
4. Using a hammer and a spacer, knock the drum off the hub. If it does not give in in any way, we treat the place where it “sits” on the protrusion of the hub with an anti-rust liquid.
5. Use long pliers to remove the guides (small) springs from both pads.
6. Using the same tool, stretch and remove first the upper return spring, then the lower one.
7. Install new pads and mount the mechanism in reverse order.

Be sure to adjust the parking brake!

As you can see, replacing brake pads on a VAZ-2110 is a very simple process and will not take you much time. Change them in time, and your car will always be obedient to you.
