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 called the parking brake for a reason: you should use it when you park your car. Many people think you only need to use your parking brake (also called the emergency brake) when parking on a hill or if your car has a manual transmission.his is incorrect; whether your car is a manual or automatic, the terrain is hilly or flat, you should use your parking brake every time you park. A car is held in âparkâ by a device inside the transmission called a parking pawl. The parking pawl can break or become dislodged and the car will roll away.
