How to Remove the Rear Drums on a 1988 GMC 2500 Truck

The rear brakes on a 1988 GMC 2500 pickup are drum brakes, which consist of brake pads, brake cylinders and the drums themselves. Over time, the lining of the drum can wear down, causing vibrations when braking and eventually brake failure. To fix the problem, you will need to remove the rear drums from the axle and replace them, or take them to a professional to be relined.

Instructions

1

Lift the rear of the truck using the jack and place jack stands underneath the axle. Lower the truck onto the stands so that the rear wheels are off the ground. Remove the lug nuts with the tire iron and take the rear wheels off the axle.

2

Spray the wheel studs and the perimeter of the brake drum with the spray penetrating oil.

3

Locate the adjusting bolt on the backside of the brake drum. Loosen the nut using an open-end wrench. Slide the brake drum off the axle shaft using both hands.
