We recommend replacement of the brake drums in axle sets for added safety and reliability

  3. Block the front wheels, raise the rear of the car, and support it with jackstands.

  5. Remove the brake drum. Tap the drum lightly with a rubber mallet in order to free it. If the drum cannot be removed easily, insert a tool into the backing plate hole and hold the automatic adjusting lever away from the adjusting bolt. Using another 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 released.
