The brakes are self-adjusting and require no periodic adjustment. If the pedal is low and there are no apparent hydraulic problems, the rear drum brake linings are excessively worn or the automatic adjusters may be defective.

The brakes are adjusted (the automatic adjusters are actuated) after drum removal or lining replacement. First, pump the pedal through its full stroke and with firm pressure repeatedly until the adjusters bring the linings out to fit the drum (the pedal comes up to a normal level). Then, adjust the parking brake cable as described later in this section. Finally, drive the car and stop normally several times to allow the adjusters to reach their final position.

When the rear brake drums must be removed, it may be necessary to loosen the rear brake shoes to pull the drum off of the brake assembly.

LOOSENING REAR BRAKE SHOES
  1. Loosen the rear wheel lug nuts.
  2.  
  3. Raise and safely support the rear of the vehicle with jackstands.
  4.  
  5. Remove the rear wheels.
  6.  
  7. Make sure that the parking brake is fully released.
  8.  
  9. Using a small prytool, remove the adjusting hole plug from the back of the drum brake backing plate.
  10.  
  11. Insert a flat bladed prytool or brake adjuster tool (C-3784 or equivalent) into the adjusting hole to engage the teeth of the drum brake shoe adjuster piston.
  12.  
  13. On the right side rear drum assembly, turn the adjusting cylinder down to loosen the brake shoes. On the left side of the vehicle, turn the cylinder up to loosen the shoes.
  14.  
  15. Continue to loosen the cylinder until the drum slides off of the assembly (the axle hub nut must be removed first).
  16.  

ADJUSTING REAR BRAKE SHOES

All though the rear brakes are self-adjusting, perform this procedure after servicing the rear brake assemblies to speed up the adjusting time.

  1. Loosen the rear wheel lug nuts.
  2.  
  3. Raise and safely support the rear of the vehicle with jackstands.
  4.  
  5. Remove the rear wheels.
  6.  
  7. Make sure that the parking brake is fully released.
  8.  
  9. Using a small prytool, remove the adjusting hole plug from the back of the drum brake backing plate.
  10.  
  11. Insert a flat bladed prytool or brake adjuster tool (C-3784 or equivalent) into the adjusting hole to engage the teeth of the drum brake shoe adjuster piston.
  12.  
  13. Tighten the adjuster cylinder until a slight drag is felt when the brake drum is rotated.
  14.  
  15. Insert a thin prytool into the brake adjusting hole along with the first tool. Using this second tool, push the adjusting lever out of engagement with the adjusting cylinder. Care should be taken so as not to bend the adjusting lever or distort the lever spring. While holding the adjusting lever out, back off the adjuster cylinder to ensure free wheeling with no brake shore drag.
  16.  
  17. Repeat the procedure on the other rear wheel.
  18.  
  19. Install the access hole rubber plugs back into the backing plate.
  20.  
  21. Adjust the parking brake after the wheel brake adjustment. Refer to the parking brake procedure later in this section.
  22.  

It is important to follow the above sequence to avoid the possibility of the parking brake system causing brake drag. This could occur if the parking brakes are adjusted before the service brakes.

Fig. Fig. 4: Use a small prytool to remove the access plug from the back of the backing plate

Premier vehicles may need periodic adjusting of the brake shoes, if the brake pedal is low.

  1. Raise the rear of vehicle and remove the rear wheels.
  2.  
  3. Remove access plate from the backing plate.
  4.  
  5. Working through access plug hole, tighten adjuster screw with brake tool or equivalent until drum is at moderate drag condition.
  6.  
  7. Hold adjuster lever away from the adjuster screw with a thin blade tool. Back off adjuster screw until rear wheels spin freely without noticeable brake shoe-to-rear brake drum drag.
  8.  
  9. Install access plug into backing plate, install wheel and lower the vehicle. Road test the the vehicle for proper operation.
