• Q: How to Service and Repair Brake Discs on 2001 Buick Century?

  A: Routine brake system service does not demand refinishing brake rotors until identified cases of excessive corrosion, pitting, cracks, heat spots, excessive bluing discoloration, scoring beyond maximum allowable specifications, lateral runout, or thickness variation beyond specifications exist. Check every rotor for these conditions to determine if refinishing is possible while maintaining a thickness above the minimum standards. The Hub Cleaning Kit (J 42450-A) should be utilized to eliminate corrosion from brake rotor hubs prior to mounting the rotor onto a brake lathe based on manufacturer guidance while maintaining secure vibration dampening attachments. When the lathe operates allow the cutting tools to touch the rotor friction areas to check the witness mark; when the mark reaches three-quarters of rotor circumference the rotor is correctly installed. Use the rotor refinishing instructions provided by the lathe manufacturer while checking the rotor thickness during each cutting procedure. A rotor must get replaced when its thickness reaches the established minimum limits. The procedure to obtain a non-directional finish requires sticking to specified speed parameters while utilizing 120 grit aluminum oxide sandpaper through a non-directional finishing tool or 150 grit aluminum oxide sandpaper with a sanding block in its absence. The brake cleaning solution of equivalent quality to denatured alcohol should be used to clean all friction surfaces after finish application. The brake rotor should be taken off the lathe before cleaning any corrosion from the wheel bearing flange using the Rotor/Drum Flange Resurfacing Kit (J 41013). This step prevents brake system pulsation and increased lateral runout.
