Fig. Fig. 1: For initial brake shoe adjustment, hold the adjuster away from the star wheel

If the brake assemblies have been disassembled, an initial adjustment must be made before the drum is installed. It may also be necessary to back off the adjustment to remove the drums.

When the brake parts have been installed in their correct position, adjust the adjusting screw assemblies to a point where approximately 3 / 8 in. (9.5mm) of threads are exposed between the star wheel and the star wheel nut.

  1. Raise and safely support the vehicle on jackstands.
  3. Remove the access slot cover and, using a brake adjusting tool or screwdriver, rotate the star wheel until the wheel is locked and cannot be turned in the clockwise direction.
  5. Back off the star wheel until the wheel rotates freely. To back off the star wheel on the brake, insert a thin screwdriver in the adjusting screw slot to hold the automatic adjusting lever away from the star wheel. Do not attempt to back off on the adjusting screw without holding the adjusting lever away from the star wheel as the adjuster will be damaged.


Free-play is not adjustable; however it can be measured for compliance. The free-play should be 1 / 16 - 1 / 4 in. (1.6-6.4mm). If free-play does not meet this specification, check for and replace the worn or damaged parts.
