ks | 1st, let me say that I don't know a lot about air brakes. With that being said, I bought a 1980 Hobbs flatbed trailer that is in very good shape, including the brakes. It made the 350 mile delivery with no problems. The guy dropped it off about a month ago, and now I'm wanting to use it. I hooked it up to the truck and I can't get nothing to move on the brakes. I've switched the glad hands ( I think you call them that) back and forth. I've opened both bleeder valves on the tanks on the trailer and nothing but air. I've tried to back up and drive forward to release them and nothing. I can't hear any air leaks on either the truck or trailer.
Thanks for any advise you can give me.
p.s. its 42 degrees out today, but it was below freezing last night.
