Your Audi S4 brake pads won't last forever. The S4 brake pads are a component of your disc braking system, and they are actually designed to wear down through normal use. Audi S4 brake pads consist of a thick frictional lining that is either riveted or glued onto a metal backing plate.

The lining of the S4 brake pads may be made with either metallic substances such as bronze or copper, or organic substances such as high-temperature resins and fillers. Audi S4 brake pad lining is similar to sandpaper in texture, and is used to generate the friction necessary to stop your car.

When you step on your brakes, the brake calipers that support your S4 brake pads press the pads against a rotating disc called a rotor. The friction that occurs between the pads and the rotors serves to stop the rotational motion safely and quickly. Most modern cars use organic Audi S4 brake pads because they are less damaging to the rotors. However, S4 brake pads made with organic material must be changed more often than those with metallic lining. Audi S4 brake pads with metallic lining provide greater stopping power and do not wear away as quickly as “soft” S4 brake pads, but the rotors must be changed more frequently. The choice of which type of Audi S4 brake pads you use should depend on your driving circumstances. No matter which S4 brake pads you choose, it is important to change them when the lining becomes less than a quarter of an inch thick. Excessive driving with worn Audi S4 brake pads will damage your rotors, and eventually your calipers.You’ll find a wide selection of S4 brake pads in our convenient online catalogue.
