REMOVAL & INSTALLATION
- Raise the vehicle and support it on jackstands. Remove the wheels.
- Release the parking brake. Disconnect the cross rod from the lever of the brake cylinder. Remove the brake drum. Place a heavy rubber band around the cylinder to prevent the piston from coming out.
- Remove the return springs and shoes.
- Clean the backing plate and check the wheel cylinder for leaks. To remove the wheel cylinder, remove the brake line, dust cover, securing nuts or plates and adjusting shims. Clearance between the cylinder and the piston should not exceed 0.015mm.
- The drums must be machined if scored or out of round more than 0.05mm. The drum inside diameter should not be machined beyond 229.5mm. Minimum safe lining thickness is 1.5mm.
- Hook the return springs into the new shoes. The springs should be between the shoes and the backing plate. The longer return spring must be adjacent to the wheel cylinder. A very thin film of grease may be applied to the pivot points at the ends of the brake shoes. Grease the shoe locating buttons on the backing plate, also. Be careful not to get grease on the linings or drums.
- Place one shoe in the adjuster and piston slots, and pry the other shoe into position.
- Replace the drums and wheels. Adjust the brakes. Bleed the hydraulic system of air if the brake lines were disconnected.
- Reconnect the handbrake, making sure that it does not cause the shoes to drag when it is released.
