The Girodisc system is a direct
replacement for the OE disc with the addition of our provided caliper
spacers. Our rotor is slightly larger than the OEM rotor at 380mm versus
365mm providing greater braking force and cooling capacity.
The central hat section of our
rotor is made from strictly U.S. sourced 6061-T6 aircraft specification
aluminum. The disc is made from our own proprietary cast iron, poured in
the USA and machined from start to finish in house at Girodisc. The rotor
utilizes 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 8 or 10 high strength alloy steel drive pins,
manufactured by Girodisc in the USA to our own specifications and cadmium
plated for a 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 washers 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.
Once the Girodisc system is in
place, simply replace the cast iron rotor when needed.
