Attention! Be sure to replace all the pads on one axle of the vehicle, even if one pad has reached the wear limit.
1. Raise the rear of the car and secure it on stands. Remove the rear wheels.
2. Remove the spring clips (indicated by arrows), the fastening pins that hold the brake pads in place.
3. Remove the spring that prevents 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 shoe.
6. If the pads are fit for further use, clean them using a wire brush and rag.
7. Before installing the pads, check that the guide bushings move freely 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. Make sure that the piston is not warped and that the piston and dust boot surfaces 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 it from the tank.
9. Install the brake pads into the caliper.
