Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Edge and Lincoln MKX
• Addresses brake fade caused by overheating through vented design
• Resolves uneven brake pad wear due to smooth rotor surface
• Corrects vibration or pulsation issues during braking
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 0.630 inches (16 mm). Clean the rotor surface to remove any protective coating or debris before mounting. Verify the rotor aligns properly with the five lug holes on the 4.5 inch (114.3 mm) bolt circle diameter. Since this rotor does not include bearings or an ABS tone ring, reuse existing components if applicable. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.
