  Q: How to replace the brake drum on GMC Sierra 1500 Classic?

  A: Before starting the Brake Drum replacement you will need the j 22364-01 drum to Brake Shoe clearance gage and j 42450-a wheel hub resurfacing kit. Begin by taking the wheel set and tire off then disengage the Brake Drum retainer when appropriate. Put tiny drops of penetrating oil directly on the parts between the wheel studs, axle shaft hub, and Brake Drum before dismounting the drum. When the Brake Drum does not budge, unscrew the rubber plug from the backing plate followed by inserting a screwdriver against the adjuster lever. Push the adjuster lever away from the adjuster and use a second screwdriver to gently lift the adjuster up until it rests in position. Remove the Brake Drum afterwards. Det bear the parts where the rear Brake Drum connects with the brake axel flange using the wheel hub resurfacing kit (J 42450-A). Measure the Brake Drum clearance with j22364-01 before setting the brake shoes position to install the rear drum and wheel then tire in the sequence.
