Quick Summary

A parking brake, also known as an emergency brake or hand brake, is a mechanical system used to stop a vehicle. It is typically operated by a hand lever or pedal and applies force to the rear brake shoes via a flexible cable. This system is crucial for preventing accidents, especially if the primary foot brake fails. In cars with automatic transmissions, a pawl engages when the gearshift is in the "park" position, further preventing the drive shaft and rear wheels from turning. The parking brake is a vital safety feature, ensuring the vehicle remains stationary when parked.123
