Help keep rear braking smooth and hold off rust with the PowerStop brake rotor EBR658EVC, a PowerStop Evolution Coated rotor finished in Genuine GEOMET rust-preventative coating. It is a direct bolt-on rear rotor for the 1998-2004 Audi A6 Quattro and the 2001-2005 Audi Allroad Quattro. See the Buyer's Guide tab for engine-specific details.
PowerStop fully coats this rotor with Genuine GEOMET, applying a thin layer of Genuine GEOMET 360 coating. The coating is designed to protect against rust and corrosion without influencing the vehicle's braking performance. The rotor is built to original equipment specifications for fitment, weight, vane count, and performance.
- Genuine GEOMET 360 coating: applied for anti-corrosion protection on the fully coated rotor.
- Bolt-on installation: direct original equipment fit and function, with no modifications necessary.
- Tight tolerances: manufactured to strict tolerances for disc thickness variation (DTV) and runout, designed for smooth, quiet performance.
- OE-matched design: weight and vane count match the original equipment design, and each rotor is 100% dynamic mill balanced.
As a disc brake rotor, it provides the friction surface that the rear brake pads clamp against to slow the vehicle. A pulsating brake pedal, vibration when stopping, deep scoring, or grinding noises are signs a rotor may need replacing. It is sold individually. Replacing both rear rotors together as a matched pair is recommended for even, balanced braking, and new pads are commonly installed at the same time.
