Disc brake pad wear sensors are an electronic safety component built into the brake pad assembly on sensor-equipped vehicles. When the brake pad wears down to the minimum safe thickness, the sensor wire makes contact with the rotor surface, completing an electrical circuit that illuminates the brake wear warning light on the dashboard. The sensor provides an early warning before the pad friction material is fully consumed, preventing metal-on-metal contact between the pad backing plate and the rotor.
