Power Stop - Front Genuine Geomet Coated Rotor Product Line

The Power Stop - Front Genuine Geomet Coated Rotor line focuses on providing rotors with a factory-style Geomet coating that enhances corrosion resistance without compromising braking performance. This coating extends rotor life by protecting against rust and environmental damage, making it suitable for vehicles like the Ford Bronco and F-150 that may encounter varied driving conditions.

Technical Specifications and Features

This vented disc brake rotor features an overall height of 65.00 mm and an outside diameter of 297.00 mm (11.70 inches), ensuring compatibility with specified Ford models. The rotor’s nominal thickness is 26.10 mm, with a discard thickness of 24.40 mm, indicating when replacement is necessary to maintain safe braking. The five-lug hole pattern with a 139.70 mm bolt circle diameter matches the factory mounting specifications for secure installation. The Geomet coating provides a rust-resistant surface, reducing corrosion and extending rotor service life.

Applications and Problem Solving

• Replacement rotor for worn or warped front disc brakes on Ford Bronco and F-150
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust-related rotor degradation in humid or salty environments
• Improves heat dissipation to reduce brake fade during heavy use
• Restores braking performance to factory specifications

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24.40 mm before installation. Clean the rotor surface to remove any protective coating residue before mounting. Verify the five-lug hole pattern and 139.70 mm bolt circle diameter match your vehicle’s hub assembly. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.
