On every car I have owned if the power brakes do not have a vacuum source such as engine not running or broken hose the brakes action is greatly reduced but I have been always able to stop the car at a greatly increased effort. The same effect as the engine not turning the power steering pump. I do not consider myself a super man but have been always able to stop car as long as hydraulic system is operational system. The manuals usually state that the brake effort will increase when the vacuum reserve is depleted
