FAQ
Frequently Asked Questions
In function, yes, they refer to the same secondary braking system in a car. 'Handbrake' (UK) focuses on manual operation by hand. 'Emergency brake' (US) focuses on its use in a crisis, though it's used identically for parking.
Primarily to secure a parked vehicle, especially on an incline. It can also be used if the main hydraulic braking system fails, though this requires specific skill to avoid losing control.
They are synonyms in American English, though 'parking brake' describes its routine use, while 'emergency brake' describes its backup safety function. In the UK, 'parking brake' is a more formal/technical term for the 'handbrake'.
It can slow the car, but it typically only brakes the rear wheels. Using it suddenly at high speed can cause the wheels to lock and the car to skid dangerously. It is not designed for rapid deceleration like the main foot brake.
