I've looked in the trailer section but with no luck . I'm am having a issue with the push release valve for the breaks.
When I hook up the trailer ,push in the release valve with all air lines connected red to red blue to blue, glad hand valves opened, the truck in drive the breaks stay locked, but if helper #2 holds /pushes the release valve the trailer wheels will roll free and helper # 2 can get out from in between the danger. The truck only had to move a couple inches. So I am reaching out and asking if this release valve can be rebuilt or does it have to be replaced and if so how or where is my question.
Thanks
