Audi vehicles are equipped with some of the most sophisticated braking systems on the market. At the heart of these systems are the brake pads. Audi brake pads are made from a high-performance ceramic compound that is designed to withstand extreme temperatures. When the brakes are applied, the pads press against the rotors, causing friction that slows the vehicle down. The Audi braking system also includes sensors that monitor pad wear and trigger a warning light when it is time to replace them. In addition, Audi brakes are equipped with a wear indicator that will make a loud squealing noise when the pads need to be replaced. By keeping an Audi's brake pads in good condition, drivers can ensure that their vehicle will stop safely in any situation. Warning Signs of Brake Pad Wear and Tear Audi brake pads are design ... read more
