  4.  
  5. Loosen the retracting spring clamp bolt on non self-adjusting brakes. On self-adjusters, remove the adjusting spring and lever at the bottom.
  6.  
  7. Using a brake spring tool, remove the return springs. On self-adjusters, also remove the adjusting cable, shoe guide plate, and the cable guide.

  11. Remove the parking brake shoe strut along with the spring on non self-adjusters only.
  12.  
  13. Grip the brake shoes at the top near the wheel cylinder, spread the shoes apart and draw the shoes, adjusting mechanism, and spring away from the backing plate. On self-adjusters, simply remove the brake shoes, as there should be no spring tension left. If the shoes are hard to remove, check for an obstructing part.
  14.  
  15. Remove the rear shoe and the parking brake shoe lever from the parking brake cable.
  16.  
  17. Remove the shoe lever form the shoe by removing the horseshoe clip form the pin.

To install non self-adjusting brakes:
  1. Assemble the rear shoe to the parking brake shoe lever, install a new clip.
  2.  

Coat all contact pints for the shoes and the parking brake mechanism with grease.


CAUTION
Do not get grease on the linings or the inside of the brake drum.

  1. Assemble the adjusting mechanism between the shoes and install the adjusting spring. The adjuster with left hand threads goes on the left wheel, right hand threads on the right wheel. Install the shoes onto the wheel cylinder and backing plate.
  2.  
  3. Install the holddown pins and springs.
  4.  
  5. Install the parking brake strut arm and make the necessary connection of the emergency brake cable.

To install self-adjusting brakes:
  1. Assemble the parking brake shoe lever and brake shoe.
  2.  
  3. Connect the parking brake shoe lever to the parking brake cable.
  4.  
  5. Apply a thin coat of grease to the backing plate and shoe contacting surfaces, and anchor pin and shoe end surfaces. Install the brake shoes, shorter lining shoe on the front, and the hold down springs and pins.
  6.  
  7. Install the spring onto the front of the parking brake shoe strut, and install the strut between the brake shoes.

  10.  
  11. Apply a thin coat of grease to the cable guide sliding surface, and fit the cable guide to the rear shoe. Install the return spring to the rear shoe with a brake tool.
  12.  
  13. Install the adjusting screw set, right hand threads on the right wheel. Apply a coat of grease to the threads, washer, and slots.
  14.  

Make sure that the threaded portion faces the front.

  1. Install the brake shoe retracting spring at the bottom, longer hook to the rear shoe.
  2.  
  3. Hook the adjusting lever to the adjusting cable spring. Insert the lever slot onto the pivot pin, and hook the adjusting lever spring onto the end of the lever.
  4.  
  5. With the parts assembled, test the auto-adjust mechanism. Insert a screw driver between the anchor pin and the rear shoe end, and move the shoe away from the pin. The adjuster should turn the adjusting screw set to expand slightly.
  6.  
  7. If the adjuster is OK, measure the maximum diameter of the brake drum, and adjust the shoes via the adjusting screw to be 0.012-0.6mm smaller to diameter.
  8.  
  9. Install the brake drum.
