Product Details and Specifications

This disc brake rotor features a plain disc finish paired with a zinc silver hat finish that provides rust resistance, helping to maintain rotor integrity over time. The directional slotted and drilled surface enhances water and debris evacuation, which is critical for maintaining braking performance in wet or harsh environments. With six bolt holes and a bolt circle diameter of 135 mm, this rotor ensures a secure fit on compatible Ford and Lincoln models. The rotor’s nominal thickness of 20 mm and discard thickness of 18.5 mm provide clear service limits for maintenance.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Ford Bronco and Lincoln Navigator
• Improves heat dissipation to reduce brake fade during heavy towing or off-road use
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Restores braking performance on Ford Expedition and F-150 models with original equipment rotor wear
• Protects against rust and corrosion in humid or salty environments

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern and center hole diameter match your vehicle’s specifications. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Follow manufacturer torque specifications for lug nuts and bolts to avoid rotor warping.

Quality Assurance
