Audi Disc Brake Pad Wear Sensor - Hella 4H0615121E

Product Information

Disc Brake Pad Wear Sensors, or Brake Pad Sensor, as they're commonly called, are used as an instrument to alert the driver when the brake pads of the vehicle are at a low level and are in need of replacement. Operation of the sensor is simple where it is wired to the brake control module with 12v and when the brake pad becomes low enough, the sensor will ultimately surface and make contact with the rotor which in turn grounds the sensor and completes the circuit which triggers the light in your instrument cluster. The Brake Pad Wear Sensor is recommended to be replaced at the time of brake pad replacement.
