There is more to it than this. You get a negative pressure in the
fluid reservoir. Air will get in. The reason US Mil vehicles use DOT5
is because that if water gets in, it doesn't mix and it stays
separate from the fluid. In the case of DOT3/4/5.1 you have
correspondingly higher boiling points of the fluid. Water is absorbed
into the fluid and small amounts aren't a problem.
Big difference between military vehicles and most vehicles is that
the military vehicles tend to sit in the weather for long periods of
time between maintenance schedules.
