Q: How to Inspect and Maintain Brake Drums and shoe on Chevrolet Astro and GMC Safari?
A: Loosen lug nuts, raise the rear of the vehicle, and support on jackstands. Block the front wheels, release the parking brake, and remove the wheel. Inspect the drum for cracks, scratches, or hard spots. If present, have the drum machined. After inspection, place the brake drum on the axle flange. Mount the wheel, tighten lug nuts, lower the vehicle, and adjust the brakes with forward and reverse stops for proper pedal action.
