Attention. Be sure to replace all the pads on one axle of the car, even if one pad has reached the wear limit. If the pads are to be reinstalled, they must be marked before removal.
Raise the front of the car and secure it on stands. Remove the front wheels.
Brakes
Remove the R-bracket from the guide pin and drive the pin out of the caliper (see fig. 9.1, 9.2).
Unscrew the nut and remove the brake hose from the suspension bracket (see fig. 9.3).
Tilt the piston housing up and secure it in this position.
Remove the brake pads (see fig. 9.4).
Clean dust and dirt from the caliper and piston.
If new brake pads will be installed, press the piston into the caliper. This can be done with a wooden rod or a hammer handle. In this case, especially make sure that the piston is not warped and that the surfaces of the piston and boot are not damaged.
Attention. When the piston is pushed in, the brake fluid is forced out of the brake cylinder into the expansion tank. Therefore, it is necessary to monitor the level of liquid in the tank, and if necessary, pump out a small amount of liquid from the tank.
When installing old brake pads, put them in their original places.
Insert the inner and outer brake pads into the caliper.
Lower the caliper down and secure with the pin and R-bracket.
Connect the brake hose to the bracket.
Repeat the operation on the opposite wheel.
Check the brake fluid level in the reservoir. The level must not exceed the mark "max". Depress the brake pedal several times to press the pads against the disc and recheck the brake fluid level in the reservoir.
Install wheels and lower vehicle.
After installing new brake pads, they should run in. On the first 200 km of run it is not recommended to make the maximum braking.
Brakes
Using pliers and a screwdriver, remove the mounting spring from the caliper (see fig. 9.5).
Remove the guide pin plugs. Unscrew the guide pins with an Allen key. Remove the piston housing from the shoe holder and hang it on a wire from the suspension strut (see fig. 9.6-9.9).
Remove the pads from the piston housing or pad holder. Normally the outer pad stays in the pad holder and the inner pad stays in the piston housing (see fig. 9.10, 9.11).
Clean dust and dirt from the caliper and piston. If new brake pads are to be fitted, press the piston into the piston housing.
Attention. When the piston is pushed in, the brake fluid is forced out of the brake cylinder into the expansion tank. Therefore, it is necessary to monitor the level of liquid in the tank, and if necessary, pump out a small amount of liquid from the tank.
When installing previously removed pads, install them in their original places. Install the outer brake shoe into the holder. Install the inner shoe with the mounting bracket into the piston and fix it. Place the piston body on the holder and insert the guide pins. Tighten the guide pins to the required torque. Repeat the operation on the opposite wheel. Check the brake fluid level in the reservoir. The level must not exceed the mark "max". Depress the brake pedal several times to press the pads against the disc and recheck the brake fluid level in the reservoir.
Install wheels and lower vehicle.
