Disc Brake

A smooth-sided steel disc, usually attached to the wheel hub. Braking is effected by hydraulically operated pistons housed in a surrounding calliper. When the brakes are applied the pads pinch the disc, causing the disc and therefore the wheel to slow down. A build-up of heat on the disc reduces braking efficiency and many discs today are either cross-drilled or ventilated to help cooling.
