• Reduced braking efficiency due to worn rotor surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.846 inches before installation. Clean the hub surface to prevent runout and ensure proper rotor seating. Use proper torque specifications for the 5 lug/stud bolts with a 0.642 inch diameter. Since this rotor does not include bearings or ABS tone rings, verify compatibility with your vehicle’s existing components. The floating disc mounting requires careful alignment during installation to maintain optimal rotor performance.
