Brake Shoes

Adjustment



The rear drum brakes are equipped with a self-adjusting mechanism. 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 drums are replaced. Adjustment can be made with a standard brake gauge or with adjusting tool. Adjustment is performed with the complete brake assembly installed on the backing plate.

With A Brake Gauge
  1. Before servicing the vehicle, please familiarize yourself with safety procedures.
  2.  
  3. Be sure parking brakes are fully released.
  4.  
  5. Raise rear of vehicle and remove wheels and brake drums.
  6.  
  7. Verify that left and right automatic adjuster levers and cables are properly connected.
  8.  
  9. Insert brake gauge in drum. Expand gauge until gauge inner legs contact drum braking surface. Then lock gauge in position.
  10.  
  11. Reverse gauge and install it on brake shoes. Position gauge legs at shoe centers as shown. If gauge does not fit (too loose/too tight), adjust shoes.
  12.  
  13. Pull shoe adjuster lever away from adjuster screw star wheel.
  14.  
  15. Turn adjuster screw star wheel (by hand) to expand or retract brake shoes. Continue adjustment until gauge outside legs are light drag-fit on shoes.
  16.  
  17. Install brake drums and wheels and lower vehicle.
  18.  
  19. Drive vehicle and make one forward stop followed by one reverse stop. Repeat procedure 8-10 times to operate automatic adjusters and equalize adjustment.
    NOTE
    Bring vehicle to complete standstill at each stop. Incomplete, rolling stops will not activate automatic adjusters.

With An Adjusting Tool
  1. Before servicing the vehicle, please familiarize yourself with safety procedures.
  2.  
  3. Be sure parking brake lever is fully released.
  4.  
  5. Raise vehicle so rear wheels can be rotated freely.
  6.  
  7. Remove plug from each access hole in brake support plates.
  8.  
  9. Loosen parking brake cable adjustment nut until there is slack in front cable.
  10.  
  11. Insert adjusting tool through support plate access hole and engage tool in teeth of adjusting screw star wheel.
  12.  
  13. Rotate adjuster screw star wheel (move tool handle upward) until slight drag can be felt when wheel is rotated.
  14.  
  15. Push and hold adjuster lever away from star wheel with thin screwdriver.
  16.  
  17. Back off adjuster screw star wheel until brake drag is eliminated.
  18.  
  19. Repeat adjustment at opposite wheel. Be sure adjustment is equal at both wheels.
  20.  
  21. Install support plate access hole plugs.
  22.  
  23. Adjust parking brake cable and lower vehicle.
  24.  
  25. Drive vehicle and make one forward stop followed by one reverse stop. Repeat procedure 8-10 times to operate automatic adjusters and equalize adjustment.
    NOTE
    Bring vehicle to complete standstill at each stop. Incomplete, rolling stops will not activate automatic adjusters.

Inspection



  1. Brake shoes must be replaced as a set and preferably on both wheels at the same time.
  2.  
  3. Measure the thickness of both linings and compare to the minimum acceptable limit given in the specifications chart. Make your measurement at the thinnest point, if one is noted. Replace both shoes on both wheels if any one lining is below the limit. State safety inspection limits may differ from these limits and would naturally take precedence if greater (thicker) than the factory values.
  4.  
  5. Replace the linings if they are scored, contaminated with brake fluid or oil or otherwise damaged. Check drum as well. The perfect brake job would involve new linings and a resurfaced drum to ensure maximum braking effectiveness and maximum component service life.
  6.  
  7. Signs of fluid leakage must be investigated. Check the wheel bearing seals if oil is noted. Check the wheel cylinder if brake fluid is found on the brake plate or linings.
  8.  
  9. Examine the lining contact pattern to determine if the shoes are bent or the drum 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.
  10.

CAUTION
Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.
