Installation Notes and Tips

Confirm rotor diameter, bolt pattern, and center bore before installation. Clean the hub mounting surface thoroughly to reduce runout and help the new rotor seat evenly. When replacing front brake rotors on Chevrolet Silverado 1500, GMC Sierra 1500, or Cadillac Escalade models, inspect pads and calipers at the same time to verify even wear and proper braking contact.
