The Brembo brake pad wear sensor tracks pad thickness and signals when replacement is due for BMW 535i GT (2011–2017), 545i (2004–2005) and 550i GT (2010–2015) rear applications. Made to OE specifications to match original performance, it features high-quality wiring and connectors that resist heat and harsh weather, and Brembo recommends replacing the sensor with every brake pad replacement.
