Product Line Details: Power Stop - Rear Genuine Geomet High Carbon Coated Rotor

This rotor is part of the Power Stop - Rear Genuine Geomet High Carbon Coated Rotor line, which focuses on providing rotors with a high carbon cast iron composition and a Geomet rust-resistant coating. This combination improves rotor durability and resistance to corrosion, making it suitable for rear brake applications on select Audi models. The solid rotor design supports consistent braking performance under normal driving conditions.

Technical Description and Specifications

The EBR658EVC rotor is manufactured from high carbon cast iron, which enhances thermal conductivity and reduces the risk of warping under heat stress. The Geomet coating applied to the rotor surface offers protection against rust and corrosion, helping maintain rotor integrity over time. With a solid rotor type, it features a 10.00 inch outside diameter and a nominal thickness of 0.39 inch, ensuring compatibility with the rear braking system of Audi A6 Quattro and Allroad Quattro vehicles. The mounting bolt hole circle diameter measures 112.00 mm with 5 lug holes, matching factory specifications for secure installation.

Common Applications and Problem Solving

• Replacement for worn or warped rear rotors on Audi A6 Quattro and Allroad Quattro
• Addresses brake pulsation caused by uneven rotor thickness
• Prevents rust-related rotor degradation in humid or wet environments
• Restores braking efficiency and pedal feel for rear disc brakes
• Suitable for routine maintenance or brake system upgrades

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the mounting bolt hole circle diameter and lug hole quantity match the vehicle specifications. It is recommended to replace brake pads simultaneously to optimize braking performance. Torque all mounting bolts to manufacturer specifications and inspect the brake system for proper operation after installation.
