Rear Brake Wear Sensor for BMW F22, F30, F32, F82 34356792292

Brake pad wear sensors are used to monitor the thickness of your vehicle's brake pad friction lining. When the minimum safe thickness is reached the pad wear sensor comes into contact with the brake rotor and opens the circuit which in turn triggers a warning on your instrument cluster notifying you that it is time to service your brakes. Whether or not the pad wear sensor has been triggered it is highly recommended to replace the pad wear sensor when replacing brake pads. They tend to become fragile with age and can easily break when removed from old brake pads causing false warnings after completing the service.
