REMOVAL & INSTALLATION




CAUTION
Brake shoes 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.

1971-86 Models

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

  1. Raise and support the rear end on jackstands.
  2.  
  3. Back off the adjusters all the way.
  4.  
  5. Remove the drums.
  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 removed tool.
  10.  
  11. Remove the adjuster cable, cable guide, adjuster lever and adjuster springs.
  12.  
  13. Remove the holddown clips or springs and remove the brake shoes.
  14.  
  15. Check the wheel cylinders for leakage. Pull back the dust covers. If there is fluid present behind the dust cover the wheel cylinder must be rebuilt or replaced.
  16.  
  17. Clean the backing plate with a brush or cloth. Place a dab of molybdenum disulfide grease on each spot where the shoes rub the backing plate.
  18.  

Always replace brake lining in axle sets. Never replace linings on one side.

  1. Install the parking brake cable and lever on the secondary shoe. Secure the lever with a washer and new U-clip.
  2.  
  3. Install the guide and self-adjuster cable on the anchor pin.
  4.  
  5. Install the shoes, one at a time, on the backing plate and secure them with the holddown springs, pins and retainers.
  6.  
  7. Install the cross-strut and spring.
  8.  
  9. Install the star wheel adjuster, spring and lever.
  10.  
  11. Install the return springs.
  12.  
  13. Make sure that the brake shoe surfaces are clean and free from any contamination.
  14.  
  15. Perform the initial brake shoe adjustment, outlined at the beginning of this section.
  16.  
  17. Install the drums and wheels, lower the truck and check brake operation. Drive the Jeep in a series of alternating forward and reverse stops. Usually 10-15 full stops in reverse are sufficient.
