  1. Remove the hub cap (if used) and loosen the lug nuts. Release the parking brake.
  2.  
  3. Block the front wheels, raise the rear of the truck, and support it with jackstands.
  4.  
  5. Remove the rear wheels.
  6.  
  7. Unfasten the brake drum retaining screws, if used. Not all models have them.
  8.  
  9. Tap the drum lightly with a mallet in order to free it.
  10.  
  11. If the drum cannot be removed easily, try one or both of the following steps:
    1. Thread two 8 x 1.25mm bolts into the threaded holes two turns at a time to lift the drum off the hub.
    2.  
    3. Insert a screwdriver into the hole in the backing plate and hold the automatic adjusting lever away from the adjusting bolt. Using another flat-bladed tool, relieve the brake shoe tension by turning the adjusting bolt clockwise. If the drum still will not come off, use a puller, but first make sure that the parking brake is fully released.

  1. Clean the drum.
