Brake Shoes

INSPECTION



Remove the drum and inspect the lining thickness of both brake shoes. The rear brake shoes should be replaced if the lining is less than 0.039 in. (1mm) thick above the rivet (so that the lining is thicker than the metal shoe backing in most cases) in order to prevent the rivet from scoring the drum. On bonded shoes the same specification should be used and the thickness of the bonded lining should be 0.039 in. (1mm) thick above the metal shoe backing plate. As with all brake service, keep in mind that local regulations take precedence over these specifications. Always check with your local authorities to be sure you are in compliance with local laws.

Brake shoes should always be replaced in sets.

REMOVAL & INSTALLATION



  1. Raise and support the rear of the vehicle safely on jackstands.
  2.  
  3. Remove the rear wheel and tire assemblies.
  4.  
  5. Matchmark and remove the brake drums.
  6.  

Always work on one side at a time. This will allow for visual comparison if you run into removal or installation problems.

  1. Remove the shoe return springs and actuator link, then remove the shoe guide from the stud at the top of the backing plate.
  2.  

Special brake spring tools are available from most auto supply stores, which will ease the removal and installation of the return and hold-down springs.

  1. Remove the shoe hold-down springs and pins.
  2.  
  3. Remove the actuator lever, pivot and return spring.
  4.  
  5. Remove the parking brake strut and strut spring, then remove the parking brake lever from the shoe (it may be easier to wait until the shoe is being removed to separate the lever).
  6.  
  7. Remove the brake shoes as well as the adjuster screw and spring assembly.
  8.  
  9. Clean and inspect all of the brake parts. Replace parts as needed.
  10.  
  11. Check the wheel cylinders for seal condition and leaking.
  12.  
  13. Inspect the axle seal for leakage and replace, if necessary.
  14.  

To install:
  1. Inspect the replacement shoes for nicks or burrs, lightly lubricate the backing plate contact points, the brake cable, the levers and adjusting screws with a white lithium brake grease. Do not get any grease on the braking surface, or stopping performance will be effected.
  2.  
  3. Install the star wheel in between the two brake shoes. The star wheel should be nearest to the secondary shoe when correctly installed.
  4.  
  5. Install the adjusting screw assembly and spring to both shoes, then position the shoes to the backing plate.
  6.  
  7. Install the parking brake lever to the secondary shoe.
  8.
