When it comes to Audi S4 brakes, safety is the number one priority. There are different types of brake systems used on vehicles, including disc brakes, drum brakes and anti-lock (ABS) brake components, but your S4 brakes are most likely a disc braking system that may or may not include an ABS system. The parts of your Audi S4 brakes include hydraulic components such as the master cylinder, brake calipers, brake hose, brake lines, and a brake fluid reservoir.

There are also frictional components to your S4 brakes, which include the brake pads, rotors, and various springs and rods. Your car is likely to have front and rear Audi S4 brakes, all working on the same general principles.

A series of brake lines and hoses connects your brake pedal to the master cylinder, and the cylinder to the brake calipers. Your S4 brakes work through friction. When you apply pressure to the brake pedal, the pressure is conveyed through the hydraulic brake fluid and the force acts to move the pistons of your brake calipers. The calipers hold the brake pads against the spinning rotors, and the resultant friction stops the rotating motion of your wheels to bring your car to a halt. It is essential that all the parts of your Audi S4 brakes are in good working order. Leaking brake fluid will cause a loss of braking power, while worn brake pads will lead to slower, less reliable stopping and resultant compounded damage to your rotors and calipers.
