Big brainstorm on auto repair
Disk brakes work by squeezing two pads together on both sides of a rotating metal disk. Each wheel of your car is equipped with two of these brake pads that close together when you press on the brake pedal. 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. You could choose to ignore the sound, but the pads will wear completely away and only metal against metal will be left to stop your car.
