Product Details

Centric GCX Elemental Protection Disc Brake Rotors are engineered to match original equipment braking characteristics while adding protection against surface rust on exposed areas. The GCX FC design uses coating patterns matched to brake pad friction type and metallurgical formulations selected to align with OEM-style rotor requirements. For Audi rear brake service, this rotor supports a clean fit on vehicles such as the Audi A4 Quattro rear, Audi A5 rear, and Audi Q5 rear where the 300mm solid rotor specification is required. If you are replacing worn rear brake rotors on an Audi A4, Audi A5, or Audi Q5, part number 320.33127F provides a direct-fit solution built around the listed dimensions and mounting pattern.

What It Helps Address

• Brake pulsation from worn or uneven rear rotors
• Rust buildup on exposed rotor surfaces
• Reduced braking consistency from rotor wear
• Noise caused by damaged or heat-affected rotor surfaces
• Fitment issues when replacing a 300mm rear disc rotor on select Audi models

Installation Notes and Tips

Verify rear axle fitment by matching the 300mm rotor size, 5-lug 112mm bolt circle, 68mm center hole, and solid rotor design before installation. Confirm the vehicle’s brake configuration against the fitment list, since some Audi models use different front and rear brake sizes. Clean the hub mounting surface before installing the new rotor to help reduce runout concerns and ensure proper seating.
