Replacing the front brake pads of a VAZ 2107 with your own hands

The life and health of the driver and passengers depend on the condition of the braking system. Owners of “sevens” often independently monitor the condition and replace the brake pads of the car. This is a simple operation that does not require special tools or high qualifications. It is enough to have basic plumbing skills and know how to change brake pads on a VAZ 2107 .

↑ Front brake design of VAZ 2107

1 — fitting for bleeding the front brake drive; 2 — connecting tube of working cylinders; 3 — brake pad wear indicator wire; 4 — wheel cylinder piston; 5 — wheel cylinder clamp; 6 — brake pad lining; 7 - sealing ring; 8 — dust cap; 9 — pins for securing the pads; 10 — bolt securing the caliper to the bracket; 11 — steering knuckle; 12 — caliper mounting bracket; 13 — caliper; 14 — protective casing; 15 — cotter pin; 16 — pad pressure spring; 17 — brake pads; 18 — wheel cylinder; 19 — brake disc.

• Having disconnected the wires of the 3 front pad wear indicators from the plug connections of the wires, remove the cotter pins 15, and then the pins 9 with the springs, remove the springs 16 and the brake pads 17. Mark the pads so that during reassembly you can install them in their original places.
• Having straightened the locking plates, unscrew the two bolts 10 that secure the caliper to the bracket, and remove the caliper.

NOTE! It is possible to remove the front brake (without brake disc) complete with brake pads. In this case, it is enough to disconnect the plug connections of the brake pad wear indicator wires, disconnect the caliper hose and unscrew the caliper mounting bolts 10.

↑ Installation of front brakes

Installation of the front brake caliper is carried out in the reverse order of removal.

After installation, restore the brake fluid level in the reservoir and bleed the system to remove air.

What is needed to replace brake pads

To change the brake pads of a VAZ 2107, you will need the following tools and accessories:

• jack;
• wheel wrench;
• set of wrenches;
• hammer;
• bit or thin screwdriver;
• metal brush;
• rag (rags);
• a powerful flat-head screwdriver or pry bar;
• pliers;
• screwdriver;
• WD-40;
• new pads.

Important: VAZ 2107 pads must be changed only as a set: both left and right at the same time.

The front brakes of the “seven” are disc type, the rear brakes are drum. Accordingly, the design of the pads and the procedure for replacing them are different.

↑ Front brake caliper parts

1 - piston; 2 — dust cap; 3 - sealing ring; 4 — caliper with cylinders; 5 — connecting tube of wheel cylinders; 6 — air release fitting; 7 — pad pressure springs; 8 — brake pad mounting pins; 9 — cotter pins; 10 — springs; 11 — lining wear indicator wire; 12 — brake pads.

Recommendations

If for some reason you do not want to install new ones, then you can swap the inner pad with the outer one. Thanks to this, their wear will be uniform, and they will brake with uniform force.

Front brake pads are replaced when the friction lining thickness is 1.5 cm or less. With such wear, you will be bothered by squeaks and squeaks when you press the brake, and the quality of braking will be worse.

Remember, a properly functioning braking system is the key to safe driving.

Before you start removing it, it is recommended to buy a repair kit for the front calipers. It includes: “gulls”, guide fingers, and their springs. This is necessary so that during the replacement process the pressure springs may “fly out” in an unknown direction, the fingers will not want to lick out of their seats, they will have to be cut off, the guide springs and “gulls” may lose their elasticity.

Before installing the fingers, it is recommended to lubricate them with a thin layer of lubricant (lithol) so that they fit freely into the holes. If the new pad does not want to “climb” into place, you need to try to recess the piston of the brake cylinder even more or lightly tap it with a hammer, driving it in. Knock only on the steel part of the block, without catching the feredo. It will fit in with tension, but after several tens of kilometers it will rub in and take its position.

Before leaving, be sure to press the brake pedal several times to bleed the brakes. During the replacement process, we compressed the cylinder pistons; now they need to be returned to their original position so that they press the pads against the brake discs. Don't be alarmed, the pedal may fall to the floor the first two times. After the brake fluid fills the cylinders, it will regain its former elasticity.

↑ Disassembly and assembly of the front brake

• Disconnect tube 5 and remove dust caps 2 from the cylinders.
• Then, pumping a stream of compressed air through the brake fluid inlet, push the pistons 1 out of the cylinders on the caliper 4 and remove the O-rings 3 from the cylinders.

Assemble the front brake in the reverse order of disassembly. Lubricate the sealing rings, pistons and cylinder mirror with brake fluid during assembly.

After installation, restore the brake fluid level and bleed the hydraulic drive system.

Preparing for maintenance

The best place to perform operations of this kind on a VAZ 2107 is a garage box equipped for these purposes. The work is performed with the following tools:

• medium weight hammer;
• flat head screwdriver;
• drifts of the appropriate diameter;
• pliers.

A visual inspection of the discs is carried out to identify deep scratches and significant wear. In the first version, the part is polished on a special machine, and in the second it is simply changed. The condition of the brake disc should not raise any doubts among the driver.

Helpful advice : increased wear of parts is possible due to jamming of the pistons. When inspecting the brake mechanism, it is recommended to carefully check the cylinder boots. If damage is detected and the moving parts of the caliper are jammed, their immediate replacement is required.

Poor condition of discs and worn brake pads can cause an accident.

Step-by-step replacement of rear pads on a VAZ 2107

You can replace the rear drum pads using the algorithm below.

1. Raise the rear of the car using a jack and remove the wheel.
2. Remove the drum.
3. Disconnect the lower spring. To do this, you need to pry it off with a screwdriver.
4. Using pliers, rotate the cotter pins until they align with the slots located on the washer.
5. Turn the cotter pin on the other side as well.
6. Straighten and remove the cotter pin that secures the handbrake lever.
7. Remove the upper spring using a screwdriver.
8. The above actions will cause the pads to fall down. After this, you need to disconnect the lever from them.
9. Inspect the springs. If necessary, purchase a repair kit for the VAZ 2107 drum brake and replace the failed elements.
10. Reassemble everything in the reverse order of removal.

The safety of the VAZ 2107 car depends on the braking system. Therefore, if any difficulties or questions arise when replacing the pads, it is recommended to watch the corresponding thematic video. This will help you avoid maintenance errors.

When product replacement is required

Both the front and rear wheels are characterized by the use of 4 brake pads to ensure effective braking. These products differ only in design, although the principle of operation is similar.

The rear pads of the VAZ 2107 are presented in the form of an arched steel structure, on the outer part of which a friction layer is applied. It is due to the friction of this layer against the inside of the drum that the car stops. If you do not replace the brake elements in a timely manner, this will be fraught with the development of unpredictable consequences, because the most important thing for any car is the serviceability of the braking system.

It is necessary to change the rear brake pads on a VAZ-2107 when the friction lining wears down to a thickness of less than 1.5 mm. It will not be possible to determine this fact without removing the wheel and dismantling the drum. But this is one of the main ways to determine whether the brake system is faulty. There is a second option, which is more convenient and does not require dismantling the rear wheel.

To do this, you need to listen for signs of squeaking of the rear wheels, as well as grinding and lack of braking effect, but this can lead to damage to the drum itself. You can squeeze the handbrake while standing on a slope and check that it is working properly. Of course, the cable on the handbrake may become loose, but if you tighten it and still have no effect, then it’s time to start replacing the pads.

If the rear brakes are not functioning, then it is time to change the pads. It is recommended to change them as a set on both rear wheels, since they are often worn out at the same time. What is the process of replacing rear brake pads on a VAZ-2107 will be determined further.

At the beginning of the work, it should be noted that the handbrake must initially be lowered to its lowest position. This will allow you to dismantle the brake drum and thereby get to the worn parts. To begin replacing the brake pads of a VAZ 2107, it is necessary to remove the rear wheel:

• There is a drum behind the wheel, which also needs to be removed. There are no problems with this, so we move on.
• After removing the drum, it is necessary to inspect the worn pads. If the thickness of the friction lining exceeds 1.5 mm, then there is no need to replace the products. Before carrying out further work, it is necessary to clean the mechanism from dirt and dust. To do this, you can use a brush or cloth.
• If the products need to be replaced, then you need to take a screwdriver and then remove first the upper, then the lower connecting springs. If you can’t dismantle it with a screwdriver, then you should use pliers. The photo below shows the springs that should be removed.

• Next, you need to remove the clamps, which consist of a rod, a washer and a spring. These washers must be rotated 90 degrees to remove them through the slots. This is what the washers that hold the pads look like.

• Similar procedures are carried out with the second block.
• After removing the springs and clamps, the pads are removed independently.
• The parking brake locking pin is straightened. The photo below shows the location of the locking pin. Now you need to unscrew the parking brake lever. This can be done using pliers. After this, the washer is removed, then the lever.

• During the dismantling process, you will have a question, what to do with the parking brake tip? It must be disconnected from the product and then left hanging.
• If necessary, it is recommended to replace all parking brake parts that were removed from the old product with new ones.

The rear brake pads on the VAZ 2107 should be installed in the reverse order of removal. Before installation, remember to bring the brake cylinder pistons as close as possible. Despite their simple design, installing them is much more difficult than the front ones. But having completed the procedure once, all subsequent repairs will be much easier for you.

The cost of new pads starts from 800 rubles per set, but it is important to purchase high-quality products, and not Chinese “consumer goods”. Not only the service life of the products, but also the braking of the car will depend on this. This completes the replacement procedure; if you have any questions, be sure to ask them.

Replacing front pads

It’s very easy to remove the front pads on the “classic” yourself thanks to the design of the two-piston caliper:

• Clean the caliper from dirt with a wire brush.
• Using narrow-nose pliers, remove the cotter pins of the pad guide pins.
• Knock the pins out.
• Using a flat-head screwdriver, press the caliper pistons so that they go as far into the caliper body as possible.
• Remove the pads and replace them with new ones.
• Install and tighten the pins.

We install new ones

Before installing new pads, it is necessary to release the parking brake cable, as it may not allow the drum to fit onto the new pads. Assembly occurs in reverse order. The springs can cause difficulties, but if you act slowly, everything should work out. This is where the file mentioned earlier comes in very handy. Thanks to the pointed shank, you can easily hook the spring loops into the mounting holes.

During the assembly process, it may turn out that, despite the parking brake cable being completely released and the working brake cylinder being fully compressed, it is not possible to put the drum on the newly installed pads. The reason for this phenomenon may be the thickness of the linings, which often slightly exceeds the permissible limit. In this case, it is recommended to change them one at a time - first replace the more worn one with a new one, after a while we replace the second one.
