Brakes may be broadly described as using friction, pumping, or electromagnetics. One brake may use several principles: for example, a pump may pass fluid through an orifice to create friction:

1.     Frictional Brake

2.     Pumping Brake

3.     Electromagnetic Brake

4.     Hydraulic Brake

5.     Air Brake

6.     Anti-Braking System(ABS)
