Bendix Brakes won't air up

[Al]

Mike,
I can hear and feel air coming out of the bottom of the air
dryer. I see a piece that I can take off that has three bolts on it
and also has electrical lead to it. So I am going to take it off
and see if I can see something that might have been stuck. What do
you think? I can put a picture of the unit on the site if that
helps. It says Pure Air Plus and the filter on the top says Haldex
and so does the piece on the bottom.
