What might be the consequence of excessive brake use?
- Overcooling of the brakes and increase of braking efficiency.
- Correct answer: Overheating of the brakes and decrease of braking efficiency.
- Excessive use of the brakes should cause no concern.
- The power of the engine might be decreased and it might even stop working.
Why this is the answer
The correct answer in the official bank: Overheating of the brakes and decrease of braking efficiency.
Braking turns the vehicle's motion into heat, and frequent or prolonged braking heats the brakes faster than they can cool. Overheated brakes lose their grip, a problem known as brake fade, so stopping distances grow. On long downhill stretches, shift to a lower gear and use engine braking instead of riding the brake pedal. Brake use does not affect engine power.
