Why is it necessary to use the handbrake for parking only?
- The parking brake cannot be used as an emergency brake.
- Because its handle or lever is not convenient to operate.
- Because its life span is short and shouldn’t be wasted on regular braking.
- Correct answer: Because the parking brake doesn’t work on all the wheels and it doesn’t have much power.
Why this is the answer
The correct answer in the official bank: Because the parking brake doesn’t work on all the wheels and it doesn’t have much power.
The parking brake usually works on only some of the wheels, typically the rear ones, and its braking force is much weaker than the foot brake. That makes it suitable for holding a stationary vehicle, not for stopping a moving one. It can still serve as an emergency backup if the foot brake fails, but normal braking should always be done with the foot brake.
