Compatible Vehicles and Applications

• Ford F-150 (various model years)
• Ford Expedition
• Lincoln Navigator

This rotor is designed for use in standard braking systems on these vehicles, providing replacement for worn or damaged rotors to restore braking performance and safety.

Common Issues Addressed by This Rotor

• Brake pulsation or vibration due to warped rotors
• Reduced braking efficiency from worn rotor thickness
• Noise or squealing caused by uneven rotor surfaces
• Overheating and brake fade from damaged rotors
• Corrosion or surface damage affecting pad contact

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.559 inches. Replace rotors when thickness reaches the discard limit of 0.472 inches. Clean the rotor surface to remove any protective coatings or contaminants before mounting. Verify the rotor aligns properly with the 5-lug bolt pattern and center hole diameter of 3.445 inches. Since this rotor does not include an ABS tone ring, confirm compatibility with the vehicle’s ABS system. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.
