Floating brake disks provide benefits in overall braking performance in several ways. First, floating rotors allow for an aluminum center hub. Being light weight and unsprung, the aluminum center hub is accelerated, and decelerated more quickly than a standard steel disk contributing to the overall performance of the vehicle. Second, because the steel portion of the disk is separated from the center hub, it is allowed to expand and retract more uniformly than a single piece disk. This results in a higher tolerance to abuse and high temperatures.
