  Q: How to service and repair the brake drum using the J41013 Rotor/Drum Flange Resurfacing Kit on GMC Safari?

  A: Clean rust from the brake drum flange using J41013 Rotor/Drum Flange Resurfacing Kit J41013. Restore the brake drum only when scoring is severe plus you spot brake pulsation or corrosion beyond the braking surface depth. There is no need to honor the drum since it requires replacement if the largest measurement exceeds the refinish limit using a micrometer. Make a non-directional braking surface on the finished part with regular aluminum oxide sandpaper at 120 grit. Use brake parts cleaner GM P/N 12377981 (12377981) or an equivalent to cleanse the braking surfaces before further repairs. Tighten wheel nuts with equal force to the correct specifications to stop brake vibrations which damage rotors.
