• Q: Under What Conditions Should Brake Discs Be Serviced and What Tools Are Needed for Refinishing on 2000 Buick Century?

  A: Professional refinishing of brake rotors requires particular conditions when the rotor brake surface shows major wear from scoring or if brake pulsation occurs due to excessive lateral runout or thickness variation and if corrosion extends beyond the rotor surface. A service technician requires the Hub Cleaning Kit (J42450-A) and the Rotor Resurfacing Kit (J41013) when performing this process. Cleaning of mating surfaces between rotor and flange requires the Hub Cleaning Kit (J42450-A) to remove rust and foreign materials because omitting this step will both increase lateral runout and produce brake pulsation. The brake rotor needs replacement with a new one if the micrometer readings at its thinnest point exceed the minimum specification. The Rotor Resurfacing Kit (J41013) helps clean brake rotor flange rust before you complete rotor refinishing according to lathe manufacturer guidelines. Conduct non-directional surface preparation through the usage of 120-grit aluminum oxide sandpaper together with a non-directional rotor finisher if available. Braking surfaces must be cleaned using GM P/N 12377981 or its equivalent brake parts cleaner after which wheel nuts must be evenly tightened to the proper torque specification to stop brake pulsation along with rotor damage.
