让那些心理阴暗的人发抖去吧。如同那篇让乙醛脱氢酶突变基因携带者们（喝酒立刻脸红的中国人）远离酒，我的文章可以让那些在高速路上碰到汽车突然死火或突然加速的人明白了刹车与真空的关系，便可救命。很多人在高速路上发动机突然死火，前边又赶上了突然减速，慌张张踩刹车、松开、再踩、再松开，把真空放掉后车子再也刹不住了，

This is not correct.
真空is functioned to release break, not to apply break. If you have a soft break, such as air in the system, you have to pump a few times to apply break.
