INSPECTION



  1. Remove the brake drum.
  2.  
  3. Using a ruler, measure the shoe lining thickness. Be sure the shoes are not worn unevenly.
  4.  
  5. When replacing brake shoes, always check the surface of the brake drums for scoring or wear. The brake drums should resurfaced or machined if badly scored.
  6.  

REMOVAL & INSTALLATION



See Figure 1


CAUTION
Brake shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

If you are not thoroughly familiar with the procedures involved in brake replacement, disassemble and assemble one side at a time, leaving the other wheel intact, as a reference. This will reduce the risk of assembling brakes incorrectly. Special brake tools are available to make this repair easier.

  1. Raise the vehicle and remove the rear wheels.
  2.  
  3. Release the parking brake and remove the brake drum.
  4.  
  5. Place a heavy rubber band or clamp around the wheel cylinder to prevent the piston from coming out.
  6.  
  7. Remove the return springs, adjuster assembly, hold-down springs, and brake shoes.
  8.  
  9. Disconnect the parking brake cable from the toggle lever.
  10.  

To install:
  1. Clean the backing plate and check the wheel cylinder for leaks.
  2.  
  3. The brake drums must be machined if scored or out of round.
  4.  
  5. Reconnect the parking brake cable.
  6.  
  7. Hook the return springs into the new shoes. The return spring ends 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 lithium 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.
  8.  
  9. Install the adjuster assembly (rotate nut until adjuster rod is at its shortest point) between brake shoes. Place one shoe in the adjuster and piston slots and pry the other shoe into position. Install hold-down springs and reconnect the return springs.
  10.  
  11. Install the drums and wheels. Adjust the brakes and bleed the hydraulic system, if necessary.
  12.  
  13. Make sure the shoes do not drag when the parking brake is applied and then is released.
  14.  

ADJUSTMENT



  1. Raise and support the rear of the vehicle on jackstands.
  2.  
  3. Remove the rubber cover from the backing plate.
  4.  
  5. Insert a brake adjusting tool through the hole in the brake backing plate. Turn the toothed adjusting nut to spread the brake shoes, making contact with the brake drum.
  6.  

When adjusting the brake shoes, turn the wheel until considerable drag is felt.

  1. When considerable drag is felt, back off the adjusting nut a few notches, so the correct clearance is maintained between the brake drum and the brake shoes. Make sure the wheel rotates freely.
  2.
