• Q: How to Service and Repair Brake Discs on 2000 Chevrolet Express 3500?

  A: To clean the brake rotors, and repair, one should start using the Hub Cleaning Kit (J 42450-A) to clean the rust and any foreign items from the mating surface of rotor and flange as there is a high likelihood of obtaining increased lateral runout and break pulsation failure to do so. Next,check the smallest dimension of the brake rotor when using a micrometer; The replacement of its rotor is not allowed; if its size is not within the minimum thickness, the rotor should not be refinished. Instead, it should be replaced. If refinishing is required due to severe scoring, brake pulsation or corrosion below the braking surface, use the Rotor Resurfacing Kit (J 41013) like step by step to clean the rust off the rotor brake flange before you proceed to the machining process according to the break lathe manufacturer's operational instructions on it. After machining, you should produce a non-directional braking surface using a 120-grit aluminium oxide sandpaper and a non directional rotor finisher if applicable. Lastly, clean the braking surfaces with either an GM P/N 12377981 (or equivalent) brake parts cleaner, and consider that, improper wheel nut tightening can cause brake pulsation and rotor damage, so ensure to follow even tighten the wheel nuts using the proper torque specification.
