The Sebro Porsche Disc Brake Pad Wear Sensor (part number 99761275500) is a component used in Porsche vehicles to monitor the wear of the brake pads. This sensor is designed to detect when the brake pads are getting low and need to be replaced. It works by measuring the distance between the brake pad and the brake rotor, and when the pads reach a certain level of wear, the sensor will send a signal to the vehicle's dashboard warning system. This allows the driver to be alerted and take necessary action to replace the brake pads before they become too worn. The Sebro Porsche Disc Brake Pad Wear Sensor is a crucial component for maintaining safe and efficient braking performance in Porsche vehicles.
