They assume that the car owner already has a basic concept of brake components. Brakes work by pressing together two pads that rest on either side of a rotating metal disk in your wheel mechanism. Each wheel is equipped with two brake pads that close up when you press on the brake pedal of your car. These pads will, of course, wear down over time. You will know that you need brake repair when you begin hearing a metal scraping sound when pressing on the brake pedal.
