The Brembo OE brake pad wear sensor for 2009–2010 BMW Z4 rear brakes monitors pad thickness and alerts the driver when pads reach minimal safe thickness. Made to original-equipment specifications for direct-fit replacement, it restores the factory warning function. High-quality wiring and connectors resist heat and harsh weather, and Brembo recommends replacing the sensor with every pad change.
