What is the function of the vehicle’s auxiliary (parking/hand) brake?
- Correct answer: To secure the vehicle from moving or going downhill..
- To assist the driver during a “hill start” only.
- Its use prevents wear of the service brakes (foot brake)?
- To enhance the braking force of the vehicle’s brakes.
Why this is the answer
The correct answer in the official bank: To secure the vehicle from moving or going downhill..
The auxiliary, or parking, brake is meant to hold the vehicle in place when it is parked or standing, so it does not move or roll downhill. It does not replace the foot brake, which does the normal stopping while driving. It also does not add braking force, and it is not used in daily driving to save wear on the service brakes.
