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

This rotor is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which features rotors coated with a Geomet rust-resistant finish. This coating helps protect the rotor surface from corrosion and rust, extending the service life and maintaining braking efficiency. The vented design enhances heat dissipation, reducing the risk of brake fade during extended use.

Technical Specifications and Features

The AR85204EVC rotor is a vented disc type, which allows air to flow between the rotor surfaces to cool the brakes more effectively. It has a nominal thickness of 1.27 inches (32.20 mm) and a discard thickness of 1.20 inches (30.50 mm), ensuring safe replacement intervals. The rotor measures 13.58 inches (345.00 mm) in outside diameter and has an overall height of 2.24 inches (56.80 mm). It mounts using a 5-lug pattern with a bolt hole circle diameter of 4.50 inches (114.30 mm), matching factory specifications for the Ford Explorer and Lincoln Aviator front brakes.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Ford Explorer and Lincoln Aviator
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore proper braking performance and pedal feel
• Prevents rust and corrosion-related rotor damage with Geomet coating
• Improves heat management to reduce brake fade during heavy use

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 1.20 inches (30.50 mm). Clean the rotor surface to remove any protective coating residue before mounting. Verify the 5-lug bolt pattern and 4.50-inch bolt hole circle diameter match the vehicle hub. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The Geomet coating provides enhanced corrosion resistance to extend rotor life. While specific warranty details are not provided here, Power Stop products typically come with a limited warranty against defects in materials and workmanship.
