A common misconception about brakes is that the brakes are squeezed against a drum or a disc, and the pressure of the tightening action slows down the vehicle. This is, in fact, a part of the reason to slow down a vehicle. Loads are devices that reduce the speed of a moving machine component by absorbing energy. The energy thus absorbed is converted into heat and released into the atmosphere or absorbed in another medium. Clutches are the devices used to couple or uncouple two rotating machine components as and when desired.
