Warning! Always replace all pads on one axle of the vehicle, even if one pad has reached the wear limit. If the pads are to be reinstalled, mark them before removal.
1. Raise the rear of the car and secure it on stands. Remove the rear wheels.
2. Mark the location of the anti-bounce spring, then use a steel rod or screwdriver to push out the lower and upper brake shoe mounting pins from the outside.
3. Remove the anti-rattle spring.
4. Using a special tool or pliers, remove the outer brake pad from the caliper.
5. Using pliers, remove the inner brake pad from the caliper.
6. Clean the caliper from dust and dirt.
7. Measure the thickness of the brake pads.
8. If the pads are fit for further use, clean them using a wire brush and rag.
9. If new brake pads are to be installed, press the piston into the caliper with the handle of a hammer. Make sure that the piston is not warped and that the surfaces of the piston and dust boot are not damaged. When the piston is pushed in, the brake fluid is forced out of the brake cylinder into the expansion tank. Therefore, constantly monitor the fluid level in the tank, and if necessary, pump out a small amount of it from the tank.
10. Check that the notches in the piston are at an angle of 23° to the horizontal line. If necessary, turn the piston to the required position.
11. Install new brake pads into the caliper. Check that the pads move freely in the caliper.
12. Install the anti-bounce spring on the pads, then insert the brake pad mounting pins from the inside while simultaneously pressing the anti-bounce spring.
13. Press the brake pedal several times to press the brake pads against the brake disc.
14. Repeat the above steps on the second wheel.
15. Install the wheels and lower the vehicle.
16. Check the brake fluid level.
