About the Power Stop - Front Genuine Geomet Coated Rotor Line

This product is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which focuses on delivering rotors with factory-level quality and corrosion resistance. The Geomet coating applied to these rotors provides enhanced protection against rust without compromising braking performance. This line is designed to meet or exceed OEM specifications, making it a suitable replacement for front disc brake rotors on compatible vehicles like the Hummer H3 and H3T.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Hummer H3 and H3T
• Addresses brake noise caused by rust or uneven rotor surfaces
• Improves braking consistency by reducing heat-related fade
• Prevents premature rotor corrosion in humid or salty environments
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 26.50 mm to maintain safety standards. Use proper torque specifications for the 6 lug bolts on the 139.70 mm bolt circle diameter. It is recommended to replace brake pads simultaneously to optimize braking efficiency and rotor lifespan.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet strict quality control standards and are coated with Geomet for corrosion resistance. While specific warranty details for part number AR8769EVC should be confirmed with the manufacturer, Power Stop typically offers limited warranties covering defects in materials and workmanship.
