The Audi brake rotors are primary components in the brake system, the surface upon which the brake pads are pressed to create the friction that slows and stops the motion of the vehicle wheels. The brake pads are squeezed against the Audi rotors by the caliper when the brake pedal is depressed inside the vehicle, and are released from the surface when the pedal is let back up, allowing the vehicle to move. Audi brake rotors are generally made of cast iron, and are used on most vehicles in production today, although some still are equipped with drum brakes in the back wheels. There are several variations of Audi brake rotors depending upon the type of vehicle and its use. The most common type of Audi brake rotors, standard in most models, are the ventilated rotors that are cast with fins in the center joining the two contact surfaces to aid in cooling. There are high performance Audi rotors that are drilled with a number of small holes in the surface for better cooling and to enable more efficient shedding of water from the surface. Slotted Audi brake rotors are also high performance parts that use shallow channels in the surface for better shedding of used brake material from the pads.
