Will power steering and power brakes function normally if the engine stalls?

Power steering and power brakes rely on the engine to operate normally, as they typically utilize hydraulic systems powered by the engine's pump. If the engine stalls, these systems will lose their source of hydraulic power, leading to reduced functionality. In the case of power brakes, while you may still be able to apply the brakes, the assist that makes it easier to stop will be diminished, requiring significantly more effort to bring the vehicle to a halt. Similarly, power steering would become much heavier and harder to steer without the engine's assistance.

Therefore, the statement regarding power steering and power brakes functioning normally if the engine stalls is not accurate. The correct understanding is that stalling the engine significantly impairs these systems' effectiveness. Hence, while it may seem intuitive to think that there could be some residual function, the truth is that both power steering and power brakes are engineered to rely on engine performance for optimal operation.
