• Squealing or noise from worn rear pads
• Reduced braking response from thin friction material
• Brake warning light service tied to pad wear sensors
• Routine rear brake maintenance on OE-style applications

Confirm the rear sensor requirement before ordering: BPS-73021 is listed for several A4, A5, S4, S5, and RS5 applications, while BPS-74004 is listed for Q5, SQ5, and A7 Sportback applications. Verify rotor condition, caliper hardware condition, and pad shape against the vehicle before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
