Audi A4 brake rotors are part of the smooth and efficient disc brake system, working with other brake components to bring your vehicle to stop when you apply the brakes. Made of cast iron, A4 brake rotors provide the contact surface upon which the brake pads produce the friction that slows and stops the motion of the wheels. Most vehicles are equipped with Audi A4 brake rotors that use a series of cooling fins between the contact surfaces on each side, designed to dissipate the heat produced by the friction of the braking process.

Efficient heat management is crucial to the brake performance, avoiding the potential for dangerous overheating in the A4 brake rotors that can cause them to warp or glaze, interfering with their ability to work with the brake pads to stop the vehicle. Brake fade can become a problem if the Audi A4 brake rotors are allowed to build excessive heat, causing temporary brake failure.

A variety of custom A4 brake rotors are made to alleviate these hazardous situations, providing better braking performance in any vehicle, but especially beneficial in high performance vehicles or those that see heavy use. Some of these custom Audi A4 brake rotors are drilled with a series of small holes to provide better heat dissipation, and others are equipped with shallow channels to shed both water and used brake pad material more efficiently. Some custom A4 brake rotors use both methods to maximize the safety and performance of the brake system.
