CAUTION
Brake shoes may 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.

A brake spring removal tool and a brake adjusting gauge are required for this procedure.

  1. Raise and support the vehicle safely with jackstands.
  2.  
  3. If the brakes have never been serviced before, the drums will be held on the wheel studs with spring nuts. Remove the spring nuts and discard.
  4.  
  5. Turn the adjustment starwheel so that the brake shoes are retracted from the brake drum and remove the brake drum.
  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 U-clip and washer securing the adjuster cable to the parking brake lever.
  10.  
  11. Remove the adjuster cable, cable guide, adjuster lever and adjuster springs. Remove the return springs with a brake spring remover tool.
  12.  
  13. Remove the hold-down retainers and springs, then remove the brake shoes.
  14.  

To install:
  1. Clean the backing plate with a brush or cloth. Place a dab of Lubriplate® on each spot where the brake shoes rub on the backing plate.
  2.  

Always replace brake linings in axle sets. Never replace linings on one side or just on one wheel.

  1. Thoroughly clean and lubricate the adjuster cable guides, adjuster screw and pivot, parking brake lever and lever pivot pin with multi-purpose grease.
  2.  
  3. Apply a thin coat of multi-purpose chassis lube to the mounting pads on the backing plate.
  4.  
  5. Transfer the parking brake actuating lever to the new secondary shoe.
  6.  
  7. Position the brake shoes on the backing plate, then install the hold-down springs and retainers. Don't forget to engage the parking brake lever with the cable.
  8.  
  9. Install the parking brake actuating bar and spring between the parking brake lever and primary shoe.
  10.  
  11. Install the self-adjusting cable, cable guide and upper return springs.
  12.  
  13. Thoroughly clean the starwheel and lightly lubricate the threads with lithium based grease.
  14.  
  15. Install the starwheel.
  16.  
  17. Install the self-adjusting cam and lower spring. A big pair of locking pliers is good for this job.
  18.  
  19. Check the surface of the brake shoes for any grease that may have gotten on them. If dirty, lightly clean with a piece of sandpaper.
  20.  
  21. Adjust the brakes, install the brake drum and wheel. Lower the vehicle and test drive.
  22.  

ADJUSTMENT



These brakes are equipped with self-adjusters and no manual adjustment is necessary, except when brake linings are replaced. After replacing the brake shoes, perform the following adjustment procedure:

  1. Insert the brake gauge in the drum and fully expand until the gauge inner legs contact the drum braking surface. Then lock the gauge in position.
  2.  
  3. Reverse the gauge and install it on the brake shoes. Position the gauge legs at the shoe centers. If the gauge does not have a light drag fit, adjust the shoes.
  4.  
  5. Pull the starwheel away from the automatic adjuster lever. Turn the starwheel by hand to expand or retract the shoes and recheck with the brake gauge.
  6.  
  7. Install the brake drums, lower vehicle and make final adjustment.
  8.  
  9. Final adjustments on drum brakes take advantage of the systems self-adjustment mechanism. Drive the vehicle and make one forward stop followed by on reverse stop. Repeat the procedure 8-10 times to equalize adjustment between the two sides. Bring the vehicle to a complete stop each time. Rolling stops will not activate the self-adjuster mechanism
