If our car is equipped with a brake booster, what will happen if the engine is stopped and the ignition is off?
Mechanics (different vehicle systems)
Explanation
The **brake booster** is a system that helps reduce the effort needed to press the brake pedal. It works when the engine is running, using the vacuum pressure generated by the engine to assist in braking.
- If the engine is **off** and the ignition is **off**, the brake booster cannot function because there is no vacuum available to assist in braking.
- In this situation, the driver will have to **apply more pressure on the brake pedal** to stop the vehicle, as they will not have the assistance of the brake booster.
Therefore, it is important to be aware that without the brake booster, the physical effort required to brake will be greater.
