Technical Details and Compatibility

This disc brake rotor is designed with a vented construction featuring straight vanes, which enhances airflow and cooling during braking. The floating disc mounting style allows for slight movement to accommodate thermal expansion and reduce stress on the rotor. With a nominal thickness of 0.787 inches and a discard thickness of 0.709 inches, this rotor provides a clear service life indicator for maintenance. The rotor’s dimensions, including a 9.949-inch outside diameter and 4 lug holes spaced on a 4.252-inch bolt circle, ensure proper fitment on compatible Ford and Mercury vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Improving heat dissipation to prevent brake fade during extended use
• Restoring smooth braking performance on Ford Contour, Mercury Cougar, and Mercury Mystique
• Eliminating noise and vibration caused by damaged or uneven rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of rust or debris before installation. Verify the rotor thickness is above the discard thickness specification of 0.709 inches. Use proper torque specifications for the 4 lug nuts on the 4.252-inch bolt circle to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, confirm compatibility with your vehicle’s braking system. It is recommended to replace brake pads simultaneously for optimal braking performance.
