Brembo 19-20 Audi A8 Quattro/2019 e-tron Quattro/17-20 Q7 Rear Premium UV Coated OE Equivalent Rotor

Brembo 09.D424.11 Prime Rear Rotor Built for Audi's Heaviest Platforms

The Brembo 09.D424.11 is a Prime series vented rear rotor engineered as an OE-equivalent replacement for a broad range of Audi's performance and luxury platforms, including the A6 Quattro, A7 Sportback, A8 Quattro, e-tron, e-tron Sportback, Q7, and Q8. At 350mm in diameter and 28mm thick, the 09.D424.11 is built from high carbon cast iron and protected with a solvent-free UV coating that shields all surfaces, including the braking faces, from corrosion during storage and break-in. The internally vented construction ensures consistent heat dissipation during repeated heavy stops, critical for the heavier curb weights of Audi's SUV and full-size luxury platforms. Brembo is the OE brake supplier for Audi, and the 09.D424.11 meets or exceeds every original equipment specification for a direct, no-modification installation. Sold individually, two rotors are required for a complete rear axle replacement.

Frequently Asked Questions

The 09.D424.11 fits the Audi A6 Quattro and A6 allroad (2019-2024), A7 Sportback (2019-2024), A8 Quattro (2019-2024), e-tron and e-tron Sportback (2019-2023), Q7 (2017-2024), Q8 (2019-2024), and Q8 e-tron (2024). Fitment requires the PR number 2EH brake package. Always verify your brake PR code using your vehicle's window sticker or by contacting an Audi dealer with your VIN.

PR codes are Audi's factory option codes that identify specific equipment packages, including brake configurations. The PR number 2EH identifies the specific rear brake package that uses the 09.D424.11 rotor. Your vehicle's PR codes are listed on the label inside the spare tire well or in your vehicle's documentation. You can also have a dealer look up your vehicle's PR codes using your VIN.

Yes. Brembo strongly recommends replacing both rear rotors as a matched pair to maintain balanced braking force and prevent the vehicle from pulling during braking. The 09.D424.11 is sold individually, so two units are required for a complete rear axle replacement.

Yes. Brembo recommends replacing pads and rotors at the same time for optimal braking performance and rotor life. Installing worn pads on new rotors transfers pad material unevenly onto the new rotor surface, causing pedal pulsation and premature wear. Brembo's NAO/Ceramic and Low-Met pad formulations are specifically engineered to work with Brembo Prime rotors.

Brembo Prime rotors are OE-equivalent quality replacement parts that meet or exceed original equipment specifications in dimensions, material, and performance. They are produced by Brembo using the same quality standards as the brake components supplied directly to Audi during vehicle production. The Prime designation means this is a direct replacement, not an upgrade performance variant.

No. The solvent-free UV coating on the braking surfaces burns off cleanly during the first few brake applications. The coating on the hat, vanes, and non-braking surfaces remains to provide long-term corrosion protection. No cleaning or preparation of the braking surface is required before installation.

Vehicles like the Audi Q7, Q8, and A8 Quattro have significant curb weights often exceeding 5,000 lbs. During repeated or heavy braking events, rear rotors on these vehicles can generate substantial heat. The internally vented construction of the 09.D424.11 creates airflow through the rotor disc during rotation, dissipating heat more effectively than a solid rotor and reducing the risk of brake fade, thermal cracking, and rotor warping over time.

Brembo backs their Prime rotors with a 2-year warranty against defects in materials and workmanship. Brembo is the OE brake supplier for Audi and stands behind the quality of their replacement components across their full product line.

Installation Instructions

1. Safely lift the vehicle and support on jack stands. Remove the rear wheel.
2. Remove the brake caliper mounting bolts and hang the caliper without straining the brake hose. If equipped with an electronic parking brake, retract the rear piston using an appropriate tool before removing the caliper.
3. Remove the brake caliper bracket mounting bolts and set aside.
4. Remove the rotor fixing screw and slide the old rotor off the hub.
5. Clean the hub face thoroughly to remove rust and debris for flat rotor seating.
6. Install the new Brembo 09.D424.11 rotor and secure with the fixing screw from the included kit.
7. Reinstall the caliper bracket and caliper, torquing all hardware to specification per the Audi workshop manual.
8. Reset the electronic parking brake actuator if applicable following the manufacturer's procedure.
9. Pump the brake pedal to seat the pads before moving the vehicle.
10. Reinstall the wheel and torque lug bolts to specification. Perform a bedding procedure before returning to normal driving.
