  Q: What tools are required to service and repair brake drums, and what steps should be followed for refinishing on Buick Regal?

  A: Service and repair of brake drums need the J 41013 Rotor/Drum Flange Resurfacing Kit with J 42450-A Hub Cleaning Kit. You should refinish brake drums only if you see signs of extreme rusting, damage spots, broken areas, intense discoloration from heat or if the brake drum wears past standard specification levels or runs out of line more than permitted. Check the brake drum surface for damage and measure its size when you take off all wheel components. Use the J 41013 to wipe off drum corrosion before setting up the brake drum on the lathe as prescribed by the manufacturer. Make sure vibration dampening hardware stays fixed during installation. Test the brake drum mounting accuracy by running the lathe and applying the cutting tool to touch the friction surface. When the witness mark passes three-quarters around the surface or more the setup position is right. Use the lathe tools just as the manufacturer specifies while measuring the drum thickness at every stage of work. The brake drum must get replaced when its diameter becomes more than the authorized limit during the refinishing process. Follow guideline speed settings to make a non-directional surface and use 120 grit aluminum oxide sandpaper when you have the finishing tool or sand fabric surface with 150 grit aluminum oxide sandpaper and a low-tech block. Use broken alcohol or brake cleaner to wipe friction areas after applying the final touch and eliminate the brake lathe. For extreme cases apply J 42450-A to remove corrosion from the wheel bearing flange and stop brake system pulsation.
