  Q: What should you consider before refinishing brake drums on Chevrolet Lumina?

  A: Proceed with brake drum refinement only when the main complaints do not include brake noise sounds or sealant damage issues. You need to refinish brake drums when deep corrosion exceeds the braking surface and causes pulsation while braking. Check the drum brake diameter using a micrometer then replace it with a new part if the largest measurement goes above the maximum modification size. Drum refinishing on brake lathe demands J 41013 Resurfacing Kit to remove rust from the brake drum flange before you follow brake lathe manufacturer instructions to achieve the ideal non-directional braking surface for proper brake operations. Sand the brake surface with non-directional 120 grit aluminum oxide sandpaper after machining and clean it with GM P/N 12377981 or brake parts cleaner substitute. Proper wheel nut tightening with equal amounts of torque protects the braking system from pulsation and keeps rotors intact.
