Product Line Details: Power Stop - Rear Genuine Geomet Coated Rotor

This rotor is part of the Power Stop - Rear Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating enhances rust resistance compared to standard rotors, helping maintain braking efficiency and rotor integrity over time. The solid rotor design supports consistent braking performance for rear axle applications on compatible Ford and Lincoln vehicles.

Technical Specifications and Compatibility

The AR85181EVC rotor features a solid disc design with a nominal thickness of 11.00 mm and a discard thickness of 9.00 mm, ensuring it meets OEM standards for thickness and durability. The rotor’s outside diameter is 302.00 mm (11.90 inches), and it has an overall height of 40.80 mm (1.60 inches). It includes five lug holes arranged on a 108.00 mm bolt circle diameter, matching the mounting requirements of the specified vehicles. The Geomet coating provides a rust-resistant surface, which is critical for maintaining rotor longevity in various driving conditions.

Applications and Problem Solving

• Replacement for worn or warped rear rotors on Ford Bronco Sport and Lincoln Corsair
• Restores braking performance on Ford Escape and Ford Focus rear disc brakes
• Addresses rotor corrosion issues with a rust-resistant Geomet coating
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Ensures proper rotor thickness for safe braking and extended component life

Installation Notes and Tips

When installing the AR85181EVC rotor, ensure the mounting surface is clean and free of debris to promote proper rotor seating. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 9.00 mm. Use the correct torque specifications for the five lug nuts on the 108.00 mm bolt circle diameter to avoid rotor warping. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance.
