Lon,
I have rebuilt my own brakes (MC and all WC) and have had EXACTLY the same
spit up problem. You are pushing down on the break pedal way to hard. It is
a very very very soft push down and with luck this will then let bubbles up
from the MC. Keep the cap off and keep the reserve almost FULL. It took me
some time to get the air out of the MC but once it was out it all seems to
work. Is the truck on a VERY LEVEL SURFACE - it should be. However if I do
not drive the truck for a week or so I need to pump up the break to get
pressure back into the system. I never asked the list if this was an issue.

Subject: [oletrucks] 1950 1/2 ton brakes question
I worked on my brakes yesterday and could not get them to hold pressure. I
would pump the brake and get good peddle, then I would let off for 2 or 3
seconds and it would go right to the floor. We bled all the lines and they
seem fine. My question is this; when I remove the fill cap on the master
cylinder and push the peddle down, fluid comes shooting up from the cylinder
into the reservoir. Is this normal or do I have a bad master cylinder? Did
I not bleed it right or am I missing a trick that only ole' time truckers
know? Any help would be great!
Thanks,
Lon
