A moving vehicle has a large amount of kinetic energy, the brakes have to absorb and dissipate this energy in order for the vehicle to stop. How do the brakes do this? Each time you stop, your brakes convert the kinetic energy to heat generated by the friction between the pads and the disc. Through the process of dimple drilling and slotting the rotors not only are the rotors lighter in weight, but they cool down much quicker, in turn, will have less fade and brake fluid heating. The unique slots in the rotors help dissipate the gases released from the brake pads during braking.
This "degassing" or "out-gassing" will keep the pads in contact with the rotor resulting in less brake fade and glazing after repeated stops. Dimple drilling of the rotors allows air to flow over a larger area of the rotor, cooling the rotor material and the pad from the extreme heat generated by high-speed panic stops; a brake component's worst enemy. Heavy brake users report reduced rotor warping, increased pad, and rotor life, superior braking performance, faster stops with less fade and improved wet-weather braking.
