Attention! Be sure to replace all the pads on one axle of the car, even if one pad has reached the wear limit.
1. Raise the rear of the car and secure it on stands. Remove rear wheels.
2. Remove the spring clips (indicated by arrows), fixing pins holding the brake pads.
3. Remove the spring preventing the pads from vibrating.
4. Using pliers, remove the inner and outer brake pads from the caliper.
5. Measure the lining thickness of each brake pad.
6. If the pads are serviceable, clean them using a wire brush and a rag.
7. Before installing the pads, check that the guide bushings move easily in the caliper and that the rubber protective boots are not damaged.
8. If new brake pads are to be installed, press the piston into the caliper with a wooden rod or hammer handle. At the same time, make sure that the piston is not warped, and the surfaces of the piston and anther are not damaged. When the piston is pushed in, the brake fluid is forced out of the brake cylinder into the expansion tank, so constantly monitor the fluid level in the tank, and if necessary, pump out a small amount of fluid from the tank.
9. Install the brake pads into the caliper.
10. Reinstall the spring to prevent vibration of the pads. Install the pad retaining pins by passing them through the hole in the caliper, brake pad and center of the anti-vibration spring. Secure the pins with spring clips.
11. Depress the brake pedal several times until the brake pads press against the brake disc. Check the brake fluid level in the reservoir. Check that the inner lug of the pad is correctly aligned with one of the grooves in the caliper piston.
12. Repeat the above steps on the second wheel.
13. Install wheels and lower vehicle.
14. Check the brake fluid level.
