About the Power Stop - Front Genuine Geomet Coated Rotor Line

This Power Stop product line features rotors with a genuine Geomet coating, which provides enhanced rust resistance compared to standard rotors. The coating helps protect the rotor surface from corrosion, extending the service life and maintaining consistent braking performance. The vented rotor design improves heat dissipation, reducing the risk of brake fade during heavy use. The AR8540EVC rotor is part of this line, tailored for front axle applications on specific Ford E-150 series vehicles.

Product Specifications and Features

The AR8540EVC rotor is a vented disc brake rotor with a nominal thickness of 1.02 inches (26.00 mm) and a discard thickness of 0.96 inches (24.40 mm), ensuring safe replacement intervals. Its overall height measures 5.30 inches (133.40 mm), and the outside diameter is 11.70 inches (298.00 mm). The rotor includes five mounting bolt holes arranged on a 5.50-inch (139.70 mm) bolt circle diameter, matching the factory specifications for the compatible Ford models. The Geomet coating provides a rust-resistant surface, which is especially beneficial for vehicles exposed to moisture and road salt.

Applications and Problem Solving

• Replacement rotor for worn or warped front disc brakes on Ford E-150 and related models
• 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 rusting in humid or salty environments

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.96 inches (24.40 mm) before installation. Clean the hub surface and mounting points to prevent rotor runout. Use proper torque specifications for the five mounting bolts on the 5.50-inch bolt circle diameter. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Verify compatibility with Ford E-150, E-150 Club Wagon, E-150 Econoline, and E-150 Econoline Club Wagon models before installation.
