Hella Brake Pad Wear Sensor P8713

A brake wear sensor is an essential component of a car's braking system. It is designed to monitor the condition of the brake pads and provide early warning to the driver when they are worn out or in need of replacement. The sensor is usually attached to one of the brake pads or brake shoes, and it works by measuring the thickness of the brake lining.

When the brake pads become thinning due to wear and tear, the brake wear sensor sends a signal to the car's onboard computer system. This triggers a warning light on the dashboard, alerting the driver that the brake pads need attention. Through this sensor, drivers are able to recognize the potential safety risks of worn-out brake pads and take prompt action to have them replaced, ensuring optimal braking performance and reducing the likelihood of brake failure.
