Brembo Prime Ceramic Front Brake Pad Set for Audi A8 Quattro, S6, S7 Sportback, S8, SQ7, and SQ8 (2019–2024)

Brembo's P85170N Prime Ceramic set is a front disc brake pad set for the Audi A8 Quattro, S6, S7 Sportback, S8, SQ7, and SQ8. It uses Brembo's Prime Ceramic friction compound, which Brembo develops with a specific focus on cutting noise and vibration, so stops stay quiet and the pedal feels smooth in daily driving. The compound is also made for reduced friction wear and low dust emission, which keeps wheels cleaner and means less routine maintenance. Brembo positions Prime Ceramic as its OE-equivalent pad, intended for drivers who want factory-level fit on their car. This set cross-references Audi numbers 4M0698151BB, 4M0698151BL, 4N0698151K, and 4N0698151L. Brake pads clamp the rotor when you press the pedal, and they are a wear item that must be replaced before the friction material is gone and the backing plate starts cutting into the rotor.

This Brembo brake pad set carries a 24-month or 24,000-mile warranty.

These large Audi front calipers came in several versions, and Audi identifies them by PR code, so the code on your build sticker is the most reliable way to match this pad. On the C8 S6 and S7 Sportback and the D5 S8, this set covers PR codes 1LB with red calipers and 1LW with black calipers. On the 4M SQ7 and SQ8 it matches 1ZC red and 1ZD black calipers. On the D5 A8 Quattro it covers two applications: the L 60 TFSI with PR code 1LK and black calipers, and the L Plug-In Hybrid with PR code 1LV and unpainted calipers. If your car carries a different front brake PR code, it uses a different pad. Paint color alone is not enough, since red and black calipers share the same pad on several of these models.

Installation & Tuning Notes

Plan to replace the pad wear sensors and the retaining spring set along with this set, since these parts are needed to remove and reinstall the pads properly. The S6, S7 Sportback, S8, SQ7, SQ8, and A8 Quattro L Plug-In Hybrid take one wear sensor, 4M0-615-121-AC. The A8 Quattro L 60 TFSI uses 4M0-615-121-AB: two sensors on cars built up to 07/08/2019 and one on cars built from 07/08/2019. Every application also takes one brake pad retaining spring set, 4N0-698-231.

Common Questions

Will these pads fit my red or black calipers?
On the S6, S7 Sportback, S8, SQ7, and SQ8, this set fits both red and black caliper versions within the PR codes covered. On the A8 Quattro it fits the 1LK black caliper on the L 60 TFSI and the 1LV unpainted caliper on the L Plug-In Hybrid.

What signs point to worn front pads on these Audis?
Look for pulsation, grinding, squeaking, glazed rotors, hot spots on the rotor face, or a noticeable lip on the rotor's outer edge. Check pad thickness during oil changes or routine service against Audi's minimum spec.

Does Brembo make these pads in-house?
Brembo controls every stage of its pad production, from research and development and testing to making the friction compound and mechanical processing, under ISO 9001 and IATF 16949 quality systems.
