Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are application-specific rotors built around two core factors: coating pattern and rotor metallurgy. The GCX line uses Centric’s RS200 finish on non-mating surfaces to help resist rust and corrosion, while the high carbon formulation is selected to align with the OEM metallurgical profile for the vehicle application. Part number 320.33038H follows that approach for rear brake service on the listed Audi and Volkswagen platforms.

Common Repair Uses

• Rear brake rotor replacement for rusted or worn Audi A6 and Volkswagen Passat rotors
• Correction of brake pulsation caused by rotor wear or thickness variation
• Service replacement for rear rotors with corrosion on non-mating surfaces
• Restoration of smooth rear braking performance on select Audi 100 and A6 models
• Replacement for rotors that have reached discard thickness

Installation Notes

Verify rotor dimensions, hub fit, and rear axle application before installation. Clean the hub mounting surface thoroughly to reduce runout concerns, and inspect pads, calipers, and hardware condition during brake service. Confirm the vehicle’s brake configuration and model-year match the fitment list, especially on 1998-2001 Audi A6 and 2000-2001 Volkswagen Passat applications with listed notes.

Quality Assurance

Centric designs the GCX rotor line to match OE performance targets while using corrosion-resistant coating coverage on non-mating surfaces. The application-specific metallurgy and coating pattern are intended to support consistent fit and finish across the listed Audi and Volkswagen rear brake applications.
