2. Inspect the brake pads for wear. Use a steel ruler to check the thickness of the gasket, including the base plate, as specified in the Specifications.
3. If any brake pad is worn below the minimum thickness, replace all rear pads along with new anti-rattle springs.
4. Notice how the anti-rattle spring is placed, then knock out the pins using a fine punch (photo).
5. Remove the anti-chatter spring.
6. Push the brake pads slightly to create a small gap, then remove them from the caliper along with the intermediate plates (photo). If they are pinched, use pliers or grippers to remove them.
7. Clean dust and dirt from the caliper and intermediate plates, being careful not to inhale it. Clean the rust off the brake disc rib.
8. Press both pistons fully into their cylinders using a piece of wood or a hammer handle.
9. Check that the grooves on the pistons are turned down approximately 23°from the horizontal position. Remove old insulation (pic. 9.3) and clean the sliding sleeves. Put some grease on the bushings and install new seals on the center grooves (photo). If necessary, turn the pistons to their correct position.
10. Coat with a small amount of lubricant the upper and lower edges of the shields on the new brake pads.
11. Insert new brake pads and intermediate plates into the caliper and check that they move freely.
12. Place the anti-rattle spring on the shoes. Press the ends of the spring into the caliper.
13. Replace the brake pads on the remaining rear wheel using the procedure given in steps 4-12.
14. Depress the brake pedal several times to set the brake pads to their normal position.
15. Install the rear wheels and lower the vehicle to the ground.
