2001 Chevrolet Lumina Parts Questions & Experts Answers

• Q: Under What Conditions Should Brake Discs Be Refinished on 2001 Chevrolet Lumina?

  A: The process of refinishing brake rotors needs to be executed following specific criteria including severe scoring along with brake pulsation due to excessive lateral runout or thickness variation and corrosion which surpasses the rotor surface depth. The mating surface of the rotor and flange needs cleaning through the hub cleaning kit (J 42450-A) after brake rotor separation from the Wheel Bearing flange to prevent lateral runout increase which results in brake pulsation. Through the use of hub cleaning kit (J 42450-A) users should clean both Wheel Bearing and hub surfaces. A micrometer should measure the brake rotor thinness to establish whether you need a new rotor instead of resurfacing it. Before refinished rotor processing follow the lathe manufacturer instructions with rotor resurfacing kit (J 41013) to remove all rust completely from the brake rotor flange then deliver a top-quality surface finish for optimal braking outcomes. The next operation should involve developing a non-directional brake surface through sandpaper use of 120-grit aluminum oxide and application of a non-directional rotor finisher if available. To finish the procedure apply gm p/n 12377981 brake parts cleaner or an equivalent product to clean the braking surfaces while tightening wheel nuts to exact torque values to avoid pulsation and rotor damage.
