Common Brake Issues This Rotor Addresses

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, center hole diameter, and front left position before installation. Inspect pads, caliper condition, and hub mating surfaces at the same time to help ensure proper rotor seating and even braking performance. Because this rotor does not include bearings or an ABS tone ring, reuse or replace those components separately as required by the vehicle.
