• Covers all B9-generation Audi rear caliper configurations - both standard and red painted caliper variants on the A4/A5 are listed as compatible.

• Not compatible with carbon ceramic rotors; designed for iron/metal rotors only.
• No electronic wear sensor or hardware included.

Features

• Performance Ceramic compound eliminates rear brake squeal and dramatically reduces wheel dust - the ideal upgrade for B9-generation Audi owners who want the cleanest, quietest rear brake experience available while improving stopping power over OEM replacement pads.
• Ultra-low dust output keeps alloy wheels significantly cleaner between washes - a particularly valued benefit on Audi's large, open-spoke wheel designs where rear brake dust accumulates visibly.
• Linear friction profile maximizes ABS and stability system effectiveness - smooth, progressive rear deceleration that works seamlessly with Audi Drive Select and quattro AWD systems.
• Improved stopping power over OEM replacement pads with stable, consistent friction output from cold - no warm-up required for confident daily driving.
• Extremely gentle on rear rotors with extended pad and rotor service life.
• Backed by Hawk's limited lifetime warranty against manufacturing defects.

Product Description

The Hawk HB866Z.652 Performance Ceramic rear brake pads fit the OEM rear caliper across the Audi B9 platform - covering the 2017-2020 A4/A4 allroad, 2018-2020 A5/A5 Sportback, S4, S5/S5 Sportback, 2017-2021 RS5/RS5 Sportback, 2018-2020 Q5/SQ5, and the C8-generation A6 Quattro/allroad and A7 Sportback (2019-2020). A 2018 Q7 and 2013 first-generation SQ5 Prestige are also listed. For B9 Audi owners who daily-drive these platforms and want the cleanest, quietest possible rear brake upgrade, the Performance Ceramic compound delivers the best combination of refinement and performance available in a street pad on this chassis.

The ceramic compound's ultra-low dust output is a standout benefit on the B9 platform, where Audi's distinctive open-spoke wheel designs make rear brake dust highly visible between washes. The linear friction profile works seamlessly with Audi's quattro AWD system, ABS, and ESC for smooth, controlled rear deceleration in all driving conditions. These pads are designed for street use only and are not suitable for sustained track driving. A proper bed-in procedure is recommended after installation.
