Disc brakes
Physics
Disc brakes are mainly used in passenger cars though have recently been used on trucks. The disc brake of a car or truck serves to reduce its speed, and to stop and hold it in place when parked. On front wheels, the brake disc is mounted on the wheel hub, and a ductile iron calliper is attached to the steering knuckle flange using a bracket. The pads of a disk brake system are easily removed from the grooves of the staple. The staple has two working aluminium brake cylinders located on either side of the brake disc.
