Explain the term “service brakes”:
- Correct answer: A braking system that acts on all the wheels of a vehicle and allows slowing the vehicle down or stopping it in all road conditions.
- An auxiliary (parking/hand) brake system, designed to prevent accidents, which only acts on the wheels of the rear axle.
- A braking system that only slows the vehicle down during very steep descents, but is not used for stopping.
- A braking system that is working at times of danger only and brakes the vehicle until making a complete stop.
Why this is the answer
The correct answer in the official bank: A braking system that acts on all the wheels of a vehicle and allows slowing the vehicle down or stopping it in all road conditions.
Service brakes are the vehicle's main braking system. They act on all the wheels and allow both slowing down and stopping in all road conditions. The parking brake is a separate system. A system that acts only at times of danger does not fit the definition, because service brakes are used on every drive.
