Bendix Brakes won't air up

[Al]

Ok we got about an hour or so heading towards Charlotte and it
started blowing air from the bottom of the dryer again. We tried
repeating the process you gave to us before and got a different
result this time.

Last time, we had not air comping out of the two holes that we
disconnected the line on. This time we get hot air from the dryer
and then it switches to the bottom again. I guess the air is hot
because of the driving. Anyway, no it will not pump up the system.
Should I let it cool off and retry?

I also leveled the bird like it was before so we had no air in the
system and this did not help.

Now we are Gastonia, NC which is closer to Charlotte where we have a
couple of members recommending a service center.
