Product Details

PowerStop’s Euro-Stop sensor line focuses on direct-fit brake wear monitoring components for European vehicles. SW-0312 is engineered for front axle applications and is intended to replace a worn electronic brake pad wear sensor during brake service, helping maintain proper warning-system operation on vehicles equipped with wear monitoring.

This part cross-references Centric Parts 116.33012 and Raybestos Brakes EWS155 for the same application.

What It Helps Address

• Brake wear warning light remaining on after pad service
• Damaged or worn front brake pad wear sensor
• Loss of brake wear monitoring signal
• Sensor replacement during front brake pad and rotor service
• Fitment-specific replacement needs on Audi A6, A6 Quattro, S6, S7, RS7, and related models

Installation Notes

Install on the front brake position only. Verify rotor size and brake package before ordering, since listed fitment applies to vehicles with 400mm rotors and excludes ceramic composite brake applications where noted. Confirm connector style, terminal layout, and harness routing against the original sensor before installation.
