emergency brake = parking brake = handbrake
An emergency brake, also known as a handbrake, parking brake, or e-brake, is a safety mechanism in vehicles designed to keep them stationary when not in use or in emergency situations. It works independently of the vehicle's regular hydraulic braking system.
The primary purpose of an emergency brake is to prevent a vehicle from moving when parked, especially on a slope, by locking the wheels in place. Additionally, it can be used as a backup braking system in situations where the main brakes fail.
