"Always do a brake check first".....you can always get it moving.....but
trying to stop a 5000# m715 even at rolling speed the Flintstones way is
impossible.

wade, this is not directed at just you, but.........
people who have and drive large deadly things like old military trucks
really should get the manuals and read them. most of these trucks are
really easy to work on but you need some mechanical skill. i have this
really bad feeling that a lot of people just get their trucks and drive
them without ever checking the systems or doing routine maintenance. now
as some of you already know but many are vague on, this is how it works.
the main master cyl has a vent line going to the cover. remove the line,
then remove the fill plug to check/add fluid. this master cyl pushes
fluid to the booster where it does two things. it pushes behind the
piston of the second master cyl so that the brakes will apply with no
air. it also pushes a small piston that is part of a air pressure
regulator. this controlled air pressure is applied to the large piston
chamber that has a rod that runs forward and also pushes on the piston
of the second master cyl providing 'power brakes' there is a bleeder on
this unit and one at each wheel. pay attention to what kind of fluid
your truck has in it. take a sample and try to mix it with water, if it
mixes easily it is dot 3, if it does not mix it is silicone. the best
thing to do when you get your vehicle is to flush out the system and
replace the fluid. this way you know what is in there. remember this is
a single circuit system. any one failure will produce no brakes.
