In a vehicle, should the engine be used as a brake?

Correct answer

Yes, to avoid excessive use of the brakes and prevent them from overheating, especially on steep descents.

It is advisable to use the engine as a brake in a vehicle, especially on long descents. Engine braking involves changing down so that the engine helps maintain or reduce the vehicle's speed. This technique is important because it prevents excessive use of the service brakes, which may overheat if used excessively. Brake overheating, known as fading, reduces their effectiveness and can be dangerous. To use engine braking correctly, avoid pressing the clutch pedal, as this would deactivate its effect. When changing down to lower gears, the engine slows the vehicle, providing an additional means of control.
