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.

An inexpensive brake spring removal tool, available at most auto parts stores, will make this procedure much easier.

  1. Jack the vehicle up and safely support it so that the wheels to be worked on are off the ground.
  2.  
  3. Turn the adjuster screw's star wheel, so that the brake shoes are retracted from the brake drum.
  4.  
  5. Remove the wheels and brake drums to give access to the brake shoes.
  6.  
  7. Install wheel cylinder clamps to retain the wheel cylinder pistons in place and prevent leakage of brake fluid while replacing the shoes.
  8.  
  9. Remove the return springs with a brake spring remover tool.
  10.  
  11. Remove the adjuster cable, cable guide, adjuster lever and adjuster springs.
  12.  
  13. Remove the hold-down washers and springs, then remove the brake shoes.
  14.  

To install:
  1. Clean the backing plate with a brush or cloth. Place a dab of Lubriplate® on each spot where the brake shoes rub on the backing plate.
  2.  

Always replace brake linings in axle sets. Never replace the linings on one side or on only one wheel.

  1. Thoroughly clean the backing plate.
  2.  
  3. Apply a thin coat of multi-purpose chassis lube to the mounting pads on the backing plate.
  4.  
  5. Transfer the parking brake actuating lever to the new secondary shoe.
  6.  
  7. Position the brake shoes on the backing plate and install the hold-down springs. Don't forget to engage the parking brake lever with the cable.
  8.  
  9. Install the parking brake actuating bar and spring between the parking brake lever and primary shoe.
  10.  
  11. Install the self-adjusting cable, cable guide and upper return springs.
  12.  
  13. Thoroughly clean the adjuster screw assembly and lightly lubricate the threads with lithium based grease.
  14.  
  15. Install the adjuster screw assembly.
  16.  
  17. Install the self-adjusting cam and lower spring. A big pair of locking pliers is good for this job.
  18.  
  19. Check the surface of the brake shoes for any grease that may have gotten on them.
  20.  
  21. Install the drum and reach through the adjusting opening in the back plate with a brake adjusting tool. Turn the star wheel outward so that the brakes lock the drum, then, holding the adjusting cam with a thin screwdriver, turn the star wheel back so that the drum is free and no drag is felt.
  22.  
  23. Once the wheels are on and the vehicle is down, Back it up several times, applying the brakes to actuate the self-adjusters.
