What is the consequence on the braking system if the vehicle's engine is switched off and it is equipped with a brake booster?

Question

DentroTest · Accepted Answer

The brake booster is an active safety element that multiplies the force the driver applies to the pedal, making braking easier. This device works by using the vacuum generated by the running engine. If the engine is switched off: The brake booster stops working: The total braking capacity is not lost (the hydraulic system is still connected), but the assistance is lost. Direct consequence: The pedal feels much stiffer and you will have to apply much more physical pressure with your foot to bring the car to a stop. The other options are incorrect because the wheels do not lock up for lack of assistance (on the contrary, it is harder to lock them without enough force) and the handbrake is an independent mechanical system.
