• Vented disc brake rotor design for improved heat dissipation
• Rust-resistant Geomet coating to reduce corrosion
• Nominal thickness of 0.94 inches (24.00 mm) with discard thickness at 0.89 inches (22.50 mm)
• Overall height of 1.79 inches (45.50 mm) and outside diameter of 13.78 inches (350.00 mm)
• Mounting bolt hole circle diameter of 135.00 mm (5.31 inches) with 6 stud/lug holes

Detailed Product Description

This Power Stop rotor is part of the Power Stop - Rear Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating for enhanced corrosion resistance. The vented rotor design helps maintain optimal braking temperatures by allowing air to flow between the rotor surfaces, reducing the risk of brake fade during heavy use. With a nominal thickness of 0.94 inches and a discard thickness of 0.89 inches, this rotor meets strict specifications to ensure safe and effective braking performance. The rotor’s dimensions, including a 13.78-inch outside diameter and 1.79-inch overall height, are tailored to fit the rear brake assemblies of Ford F-150 and F-150 Lightning trucks.

Applications and Problem Solving

• Replacement for worn or warped rear disc brake rotors on Ford F-150 and F-150 Lightning
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore braking efficiency lost due to rotor corrosion or pitting
• Improves heat dissipation to reduce brake fade during towing or heavy loads
• Prevents premature rotor wear with rust-resistant Geomet coating

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the mounting bolt hole circle diameter of 135.00 mm and 6 lug holes match your vehicle’s specifications. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check rotor thickness before installation to confirm it is above the discard thickness of 0.89 inches (22.50 mm). Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance

Power Stop rotors undergo rigorous quality control to meet OEM standards for fit, form, and function. The Geomet coating provides long-lasting corrosion resistance, extending rotor life. While specific warranty details are not provided, Power Stop products are manufactured to deliver consistent braking performance and durability for Ford F-150 and F-150 Lightning rear brake applications.
