Common Applications and Issues Addressed

• Replacement for worn or warped rear rotors on Ford Explorer, Mustang, and Lincoln Aviator
• Improves braking consistency by reducing rotor overheating
• Prevents rust-related rotor degradation in humid or salty environments
• Restores proper rotor thickness to maintain safe braking distances
• Addresses noise and vibration caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is within discard limits before mounting. Use proper torque specifications for the 5 lug bolts on the 4.50-inch bolt circle diameter to avoid warping. It is recommended to replace brake pads simultaneously to ensure even wear and optimal braking performance.
