Warnings!
- Be sure to replace all pads on the same vehicle axle, even if only one is worn. If old brake pads are installed again, they must be marked before removal.
- Work with the brake mechanisms of each wheel in turn, if necessary, the assembled brake mechanism on the other wheel will act as the original.
- Remember that brake pad wear generates abrasion dust, which contains asbestos, which is harmful to health.
Remove the cap from the reservoir of the brake system and drain approximately 1 liter of brake fluid.
Loosen the front wheel bolts, raise the front of the vehicle, secure it on stands and remove the front wheels.

Front disc brake and steering knuckle: 1 - bolt and nut; 2 – rotary fist; 3 - nut; 4 – a protective casing of a forward brake; 5 - front wheel hub assembly; 6 - brake disc; 7 - hub nuts; 8 - external brake shoe; 9 - support; 10 - bolt and nut; 11 - caliper mounting bolts; 12 – a hollow bolt of fastening of a brake hose; 13 - bushing; 14 - rubber cap; 15 - fitting for air removal; 16 - guide pin; 17 - dust cover; 18 - piston seal; 19 - piston; 20 - dustproof seal; 21 - latch
Remove the two caliper mounting bolts (pic. 10.2).
Rotate the caliper up away from the brake disc. Support the caliper with your hands or secure it with twine or wire to the suspension strut so that it does not hang from the brake hose.
Use a screwdriver to remove the fixing brackets and remove the outer brake pad. Remove the sound deadening pad from the back of the brake pad.
Remove the inner brake pad by lifting it out of the caliper and remove the sound deadening pad.
Inspect the caliper boot by carefully unscrewing the edges of the boot and check for fluid leaks. If a leak is found, remove the caliper for overhaul or replacement.
Use a C-clamp to press the piston into the caliper as far as it will go.

Install soundproofing pads on new brake pads (pic. 10.3).
Correctly position the inner brake shoe and snap it onto the piston.
Insert the outer brake shoe and snap it into the caliper.
Lower the caliper into place.
Screw in the caliper mounting bolts and tighten them to the required torque.
Depress the brake pedal several times to set the brake pads with a certain clearance in relation to the brake disc, then fill the reservoir with brake fluid.
Install wheels and lower vehicle. Tighten the wheel nuts to the required torque.
Avoid hard braking as far as possible for the first few hundred kilometers of the vehicle until the new pads are completely worn in.
