Brembo front brake pad wear sensor for Audi A4/A4 Quattro (2009–2011), A5/A5 Quattro (2008–2011) and S4/S5 (2010–2011) applications. It monitors pad thickness electronically and sends a dashboard alert when pads reach minimal thickness, helping keep braking reliable. Built to OE specifications to mirror the original sensor's performance; wiring and connectors are designed to resist high heat and adverse weather. Brembo recommends replacing the sensor with each pad replacement.
