Parking Brake Shoes

Print

Adjustment



Under normal circumstances, the only time adjustment is required is when the shoes are replaced, removed for access to other parts, or when one or both rotors are replaced.

Adjustment can be made with a standard brake gauge (rotor removed) or with adjusting tool (rotor installed). Adjustment is performed with the complete brake assembly installed on the backing plate.

Rotor Installed
  1. Ensure that the parking brake is fully released. There should be a bit of slack in the cable. Loosen the adjuster if necessary.
  2.  
  3. Raise the rear of the vehicle.
  4.  
  5. Remove the rubber plugs from the adjuster slots.
  6.  
  7. Check that the wheels rotate freely. If not, determine the cause. If the shoes are too tightly adjusted, skip the next step.
  8.  
  9. Insert the adjusting tool into the slot and engage the teeth of the adjusting star wheel. Move the tool handle up, which will expand the brake shoes. Rotate the wheel while doing this until a slight drag can be felt.
  10.  
  11. Insert a thin slothead screwdriver into the adjuster slot and push the adjuster lever away from the star wheel. Back off the adjuster star wheel until brake drag is eliminated.

  13. Install the adjuster slot plug.
  14.  
  15. Repeat the procedure at other wheel. Be sure adjustment is equal at both wheels.
  16.  
  17. Lower the vehicle.
  18.  
  19. Check brake operation before driving.

Rotor Removed
  1. Ensure that the parking brake is fully released. There should be a bit of slack in the cable. Loosen the adjuster if necessary.
  2.  
  3. Raise the rear of the vehicle and remove the wheel, caliper and rotor.
  4.  
  5. Measure the drum diameter with the gauge and lock it into position.
  6.  
  7. Turn the gauge around and check the shoe diameter diagonally across at the top of one shoe and bottom of the opposite shoe (widest point). The gauge should be a light drag fit over the shoes.
  8.  
  9. If the gauge is not a light drag fit over the shoes, turn the star wheel by hand to move the shoes in or out so that the correct clearance can be achieved.
  10.  
  11. Install rotor and caliper.
  12.  
  13. Install the wheel.
  14.  
  15. Lower the vehicle.
  16.  
  17. Check brake operation before driving.

Inspection



As a general rule, riveted brake shoes should be replaced when worn to within 0.78 mm (1/32 in.) of the rivet heads. Bonded lining should be replaced when worn to a thickness of 1.6 mm (1/16 in.).

Examine the lining contact pattern to determine if the shoes are bent or the drum is tapered. The lining should exhibit contact across its entire width. Shoes exhibiting contact only on one side should be replaced and the drum checked for runout or taper.

Inspect the adjuster screw assembly. Replace the assembly if the star wheel or threads are damaged, or the components are severely rusted or corroded.

Discard the brake springs and retainer components if worn, distorted or collapsed. Also replace the springs if a brake drag condition had occurred. Overheating will distort and weaken the springs.

Inspect the brake shoe contact pads on the support plate, replace the support plate if any of the pads are worn or rusted through. Also replace the plate if it is bent or distorted.
