Centric 320.33101H Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Overview

Centric GCX Elemental Protection Disc Brake Rotor 320.33101H is a rear vented rotor built for OE-style braking performance and corrosion resistance. It is engineered for select Audi A6 and Audi A6 Quattro applications, including 2005-2011 rear fitments, with a fully coated finish for exposed surfaces and a smooth friction surface.

The GCX Elemental Protection line uses application-specific coating patterns and Centric’s high-carbon metallurgy to match OEM-style rotor requirements. For Audi A6 Quattro rear brake rotor replacement, 320.33101H is built to deliver consistent fitment, stable braking feel, and long-term protection against rust on non-mating surfaces.

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are built around application-specific coating patterns and metallurgy selection. This GCX FC-style full coating approach protects non-mating surfaces from rust and corrosion while preserving the friction surface needed for braking performance. The rotor uses a high-carbon alloy profile matched to OEM requirements for the listed Audi rear applications.

Fitment

• Fits 2009-2011 Audi A6 Quattro, rear. Notes: Vented rear disc; including armored.
• Fits 2005-2008 Audi A6 Quattro, rear.
• Fits 2006 Audi A6, rear.
• Fits 2005 Audi A6, rear.

What This Rotor Helps Address

• Rear brake rotor rust on exposed surfaces
• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from rotor wear
• Corrosion-related appearance issues on the hat and non-mating areas
• OE replacement needs for Audi A6 Quattro rear brake service

Installation Notes and Tips

Verify rotor diameter, center bore, bolt circle, and vented rear configuration before installation. Clean the hub mounting surface thoroughly to help prevent runout from debris or corrosion. Follow the vehicle manufacturer’s service procedure for pad bedding and torque specifications after installing 320.33101H.

Quality Assurance

Centric designs GCX rotors to match OE performance targets and uses coated non-mating surfaces to improve rust and corrosion protection over the service life of the rotor. This part cross-references Audi OE part number 4F0615601F for the same application.
