3. Remove the rear brake drums.
BRAKE SYSTEM, REPAIR WORK, Rear brake drum.
4. To remove the brake shoe clamps, squeeze them together and turn them. Remove 2 clamps and 2 locking pins.
5. Release the parking brake cable from the lever.
6. Release the brake pads from the piston stop grooves.
7. Rotate the brake shoe assembly around the wheel cylinder and hub and remove it.
CAUTION: Be careful not to damage the wheel cylinder boots with the brake shoe edges.
8. Wrap elastic band around the wheel cylinder to hold the pistons in place.
9. Release and remove the tension springs, having previously noted their location. Put aside the clearance adjuster and the shoe expansion bar.
10. Clean the brake shield and brake drum with brake cleaner.
CAUTION: Do not use mineral-based fluids. Their use may cause damage to rubber components.
11. Remove all rust with a wire brush. Be careful not to damage the wheel cylinder boots.
CAUTION: Do not use compressed air to clean the brakes. Particles of brake friction material may be harmful if inhaled.
12. Inspect the brake components for wear and damage.
13. Inspect the wheel cylinder boots, paying attention to traces of brake fluid leakage and their abnormal moisture. If a significant amount of brake fluid is detected, lift the seals and check for leaks. Replace the wheel cylinder and brake pads with new ones if the linings are contaminated with brake fluid.
14. Make sure that the pistons can move freely in the wheel cylinder.
15. Check the threaded surface of the clearance adjuster, nut and parking brake actuator, paying attention to wear. If necessary, replace worn parts.
16. Check the condition of the tension springs and replace them with new ones if necessary.
17. Make sure the clearance adjuster is completely released.
