Question 8174
In a vehicle, should the engine be used as a brake?
- Yes, to avoid overusing the brakes and prevent them from overheating, especially on steep downhill grades.
- No, because it wears out the clutch.
- It is not advisable because it uses more fuel.
Show answer and explanation
Correct answer: Yes, to avoid overusing the brakes and prevent them from overheating, especially on steep downhill grades.
Yes. Using a gear that lets the engine hold the vehicle back keeps you from overusing the service brake, which heats up and becomes less effective with continuous use, especially on steep downhill grades. Also, with a gear engaged and your foot off the accelerator, you use no fuel.
