  1. Using a pair of needle-nose pliers, remove the shoe return springs.
  2.  
  3. Slide the shoe strut with spring form the brake adjustment.
  4.  
  5. Slide the front shoe and remove the adjuster. Disconnect the tension spring and remove the front shoe.
  6.  
  7. Slide the rear shoe out, then remove the tension spring from the shoe.
    1. Disconnect the parking brake cable from the parking brake shoe lever.
    2.  
    3. Using a suitable spring tool, remove the hold-down spring cups, springs and pins.
    4.  

  8.  
  9. Inspect all disassembled parts for wear, rust or damage.
  10.  
  11. Using a scale, measure the thickness of the brake shoe lining. Standard thickness is 0.079 inch (2.0mm) and minimum thickness is 0.039 inch (1.0mm). If the lining thickness is at the minimum thickness or less, or if there is uneven wear of the shoes, replace the brake shoes.
  12.  
  13. Using a vernier caliper, measure the inside diameter of the disc. Standard inside diameter is 6.69 inch (170.0mm) and maximum inside diameter is 6.73 inch (171.0mm). Replace the brake disc if the inside diameter is at the maximum value or more. Replace the disc or grind it with a lathe if the disc is scored or worn unevenly.
  14.  
  15. To inspect the parking brake lining or disc for correct contact, apply chalk to the inside of the disc. Grind down the brake shoe lining to fit. If the contact between the disc and brake shoe lining is incorrect, repair it using a brake shoe grinder or replace the shoe assemblies.
  16.  
  17. Measure the distance between the parking brake shoe and lever. Using a feeler gage, measure the clearance. Standard is 0.0138 inch (0.35mm). If the clearance is not within specifications, replace the shim, with one of the correct size. Check your local parts wholesaler or dealer for the correct shim. Shims usually come in these sizes:

    0.012 inch (0.3mm)
     
    0.024 inch (0.6mm)
     
    0.035 inch (0.9mm)
     

  18.  
  19. If replacing the shim is necessary, removed the parking brake lever and install the correct size shim. Install the parking brake shoe lever with a new c-washer. Remeasure the clearance.
  20.  
  21. Lubricate all shoe sliding surfaces of the backing plate and the threads and head of the adjuster with a high temperature Lithium grease or equivalent.
  22.  
  23. Connect the parking brake cable to the to the rear shoe lever. Install the shoe hold down springs, cups and pins.
  24.  
  25. Slide the rear shoe in between the hold down spring cup and the backing plate.
  26.  


CAUTION
Do not allow the brake shoe rubbing surface to come in contact with the grease on the backing plate.

  1. Hook the one end of the tension spring to the rear shoe and connect the front shoe to the other end of the spring. Install the adjuster between the front and rear shoes. Slide the front shoe in between the hold-down spring cup and the backing plate.
  2.  
  3. Install the strut so that the spring end is forward.
  4.  
  5. Install the front and then the rear return springs using the removal tool.
  6.  
  7. Before installing the disc, lightly polish the disc and shoe surfaces with a fine grit emery cloth. Position the rotor disc onto the axle hub so that the hole on the rear axle shaft is aligned with the service hole on the disc.
