Girodisc Brake Rotors

Girodisc Brake Rotors
Girodisc RotorsTwo piece Girodisc rotors reduce unsprung and overall vehicle weight compared to one piece rotors. Girodisc rotors also have the benefit of increased ventilation and cooling while retaining it's original dimensions. This is accomplished because of the two-piece disc construction with the use of the central 6061-T6 aircraft specification aluminum “hat” section of the disc.
The disc is made from cast iron. It is a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc. The rotor and hat have a floating mount system, which utilizes high strength alloy steel drive pins, manufactured by Girodisc to their own specifications and cadmium plated for long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by grade 12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring clips on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.
