  Q: How to replace the brake drum on GMC Savana 3500?

  A:

  In order to replace the Brake Drum, it is first necessary to install the pin into the park brake lever, then to raise as well as support appropriately the vehicle. Remove the tire and wheel assembly, which has to be labeled relating to the drum to the hub. If possible, take out the Brake Drum retaining clips, and then remove the Brake Drum. If the drum is hard to remove, you then take off the access hole plug from the backing plate, slide a flat- bladed tool from the outside into the backing plate access hole through; use your other flat-bladed tool to loosen the self adjuster screw. After reinstalling the access hole plug to avoid contamination, spread some penetrating oil around the center hole of the Brake Drum and remove the Brake Drum. For installation, move the relationship mark and install Brake Drum on axle and then install the rear Brake Drum retainers if available. Disengage the pin from the park brake lever, askill on the tire and wheel assembly and readjust the rear brakes. Lower the car and with the engine turned off, slowly press the brake pedal about 2/3 of travel distance and slowly release it. Wait 15seconds, and repeat this process until a firm brake pedal is achieved, ensuring proper seating of the wheel cylinders and Brake Shoes.

  Q: How to service and repair the brake drum on GMC Savana 3500?

  A:

  In order to service and repair the brake drum, using the J 41013 Rotor/Drum Flange Resurfacing Kit (J 41013) is ideal to clean rust off the brake drum flange. Only refinish brake drum when there is heavy scoring of the braking surface or brake pulsation as a result of out-of-round quality or deeper corrosion. Take the largest diameter measurement of the brake drum using a micrometer; If it exceeds an upper limit for refinish diameter, change the brake drum as opposed to refinish. After machining, make a non directional braking surface using 120 grit aluminum oxide sand paper. At last, clean the braking surfaces with GM P/N 12377981 or similar braking parts washdown. Make sure wheel nuts are tightly fastened to the appropriate torque specification so that no damage can occur to the brake and rotors due to the pulsation in the brake.
