In cars, the parking brake, also called hand brake, emergency brake, or e-brake, is a latching brake usually used to keep the vehicle stationary. It is sometimes also used to prevent a vehicle from rolling when the operator needs both feet to operate the clutch and throttle pedals.
The parking brake is connected to the rear brakes, which do not exert as much force in braking as the front brakes and will do little to stop a vehicle moving at high speeds. Most modern applications of the parking brake is to ensure that a parked vehicle stays in place, especially on hills and other declines.
