The Brembo OE brake pad wear sensor for 2001–2006 BMW M3 models monitors pad thickness and signals when pads reach minimal material. Made to original equipment specifications to match factory signal behavior, it should be replaced with every brake pad service according to Brembo. The sensor includes robust wiring and weather-resistant connectors that resist high heat and harsh road exposure to keep the warning circuit functioning reliably.
