Explanation
Drivers should test their brakes regularly and particularly before setting out on a journey. However, if when driving they hear a scraping noise when they press the brake, the most likely reason is that the brake linings or pads are worn. In this case, brakes wont work as well as they should and the driver should have them replaced by a competent person immediately.
