It is typically installed on the brake caliper and uses a sensor to measure the thickness of the brake pads. When the pads reach a certain level of wear, the sensor will send a signal to the vehicle's dashboard to alert the driver that it is time to replace the brake pads. This helps to ensure that the vehicle's brakes are always in good working condition and prevents potential accidents due to worn-out brake pads. The Bowa Brake Pad Wear Sensor - A059024 is a reliable and essential component for maintaining the safety and performance of a vehicle's braking system.
