  1. If the drum cannot be removed easily, 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.
