Detailed Product Description

This Power Stop rear rotor is a vented disc type, designed to enhance heat dissipation during braking, which helps maintain consistent stopping power and reduces the risk of brake fade. The rotor features a Geomet coating, a rust-resistant finish that extends the rotor's lifespan by protecting it from corrosion and environmental damage. With a nominal thickness of 0.94 inches (24.00 mm) and a discard thickness of 0.87 inches (22.00 mm), this rotor meets precise specifications to ensure safe and effective braking performance. The overall height measures 3.20 inches (81.00 mm), and the outside diameter is 12.10 inches (308.00 mm), matching the exact fitment requirements for the rear brakes of Ford Bronco and Ranger vehicles. The rotor mounts with a 5.50-inch (139.70 mm) bolt hole circle diameter and includes 6 stud/lug holes for secure installation.

About the Power Stop - Rear Genuine Geomet Coated Rotor Line

The Power Stop - Rear Genuine Geomet Coated Rotor product line focuses on providing rotors with a factory-style Geomet coating that offers enhanced rust resistance compared to standard rotors. This coating helps maintain rotor integrity and appearance over time, especially in environments prone to moisture and road salt exposure. The line emphasizes durability and consistent braking performance, making it suitable for rear brake applications on compatible Ford models.

Common Applications and Issues Addressed

• Replacement for worn or warped rear rotors on Ford Bronco and Ranger
• Corrosion prevention in humid or salty environments
• Improved heat dissipation to reduce brake fade during heavy use
• Restoring proper rotor thickness for safe braking performance
• Addressing vibration or noise caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor is installed on the rear axle of compatible Ford Bronco or Ranger models according to manufacturer specifications. Verify the rotor thickness before installation to confirm it is above the discard thickness of 0.87 inches (22.00 mm). Clean the mounting surface and hub to remove rust or debris for proper rotor seating. Use the correct torque specifications on the 6 lug studs to secure the rotor firmly. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The Geomet coating provides additional protection against rust and corrosion, contributing to the rotor's longevity. While specific warranty details are not provided here, Power Stop products typically come with a limited warranty covering defects in materials and workmanship.
