  • Brake wear warning light stays on after pad service
  • Damaged or broken rear sensor wire
  • Worn sensor triggered by brake pad replacement
  • Intermittent brake pad wear indicator signal
  • Rear brake service on BMW models with electronic wear monitoring

Installation Notes

Verify the vehicle’s production date, rear brake configuration, and rotor/brake package before ordering. Several BMW applications in this listing use date-specific fitment, including 2007 328i, 2010 125i, 2010 128i, and 2008-2010 135i rear applications. Inspect the sensor routing and connector condition during brake service, and replace any damaged sensor wire before clearing the warning indicator.

Quality Assurance

Dynamic Friction Sensor Wire parts are cataloged by application to match the rear brake wear sensor requirements shown in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
