Common Brake Issues This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking performance from a worn braking surface
• Noise related to rotor scoring or uneven wear
• Service needs after pad replacement on a worn rotor
• Brake system maintenance on select Ford and Mercury vehicles

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub fitment before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect brake pads, calipers, and hardware condition during service. After installation, follow the vehicle manufacturer’s brake bedding procedure to help establish even pad transfer on the new rotor.
