I have 3 of these trucks running and a lot of parts from a couple that have been parted. Already put a glad hand on it with the capped vent.. just haven't driven for test ride yet. I'm sure it will work now especially when you figure how tight the seal was on the system with the all new glad hands components.
Thanks again,
Mike
Deuces do not have the special set up allowing remote application of brakes, so the info just relates to 5 ton and larger...don't know about the A3, too new for my brain bank. For the slow release on the deuce, I would expect collapsed rubber hoses, or a lazy airpak... be sure to put the OHT in the air pak twice a year...keeps the rust from the wet air from binding it up...
