Brake Wear Sensors are key safety components that allow worry-free driving without the need for constant visual inspection of your brake pad material. An illuminated brake lining dash light is a warning of thin brake pad material. Pads should be replaced as soon as possible, and the sensor is a required replacement once the brake lining dash has come on.
