Brembo rear brake pad wear sensor for various BMW 1‑ and 3‑Series and M3 applications covering model years around 2008–2013. The electronic sensor monitors pad thickness and issues a dashboard warning when pads reach minimal safe thickness, helping drivers avoid unexpected brake wear. Made to OE specifications for original-like performance; wiring and connectors resist high heat and harsh weather. Brembo recommends replacing sensors with every pad replacement.
