Brembo Rear Ceramic Brake Pad Set for Audi A4, A5, Q5, S4, S5, SQ5, and allroad (2008–2017)

For the rear axle, Brembo P85099N is a Prime Ceramic disc brake pad set that replaces the worn rear pads on the Audi A4, A5, Q5, S4, S5, SQ5, and allroad from 2008–2017. The pads use an NAO ceramic friction compound. Brembo tuned this compound for low noise and vibration, reduced friction wear, and low dust, which keeps wheels cleaner and cuts down on maintenance. Brembo positions Prime Ceramic as its OE-equivalent pad for drivers who want factory-style fit and feel. Each set comes with the rear pads, brake pad retaining clips, and new hardware, so you can reassemble the caliper with fresh parts. The set is made in China.

This number covers rear brakes only, so it does not replace the front pads on these cars. The set crosses to a long run of Audi rear pad numbers in the 8K0698451 and 8K0098601 families, including 8K0698451A, 8K0698451F, 8K0098601E, and 8K0698601A. That makes it simple to compare against the number on your old pads. Brembo controls every stage of its pad production, from research and development and testing to compounding the friction material and mechanical processing. Brake pads clamp the rotor to slow the car. If a pad wears past its minimum thickness, it can score the rotor and add cost to the job.
