2000 Chevrolet Venture Brake Disc Parts Questions & Experts Answers

• Q: Under What Conditions Should Brake Discs Be Refinished on 2000 Chevrolet Venture?

  A: The process of repairing brake rotors requires refinishing only when three conditions appear: severe wear on the rotor braking surface, instability from excessive thickness variation or lateral runout or deep rotor surface corrosion. Start the procedure by removing rust and foreign debris from the rotor-flange interface using the hub cleaning kit (J 42450-A) because omitting this cleaning task will create increased lateral runout which leads to brake pulsation. The brake rotor needs replacement when a micrometer shows the thinnest point exceeds minimum thickness but cleaning the Wheel Bearing and hub and using the hub cleaning kit (J 42450-A) produces acceptable results. Before completing rotor refinishing steps, machinists must use rotor resurfacing kit (J 41013) to totally remove rust from the brake rotor flange. They must then follow lathe manufacturer instructions for rotor refinishing that achieve optimal surface finish for preventing poor braking outcomes. The next step requires a 120-grit aluminum oxide sandpaper to produce a non-directional surface on the brake rotor along with the utilization of any available non-directional finisher. Brake parts cleaner gm p/n 12377981 or its equivalent should be used to clean the braking surfaces before wheel nuts get tightened to their appropriate torque specification for preventing brake pulsation and rotor damage.
