I need a education on trailer brakes
This older Great Dane trailer I bought has super grabby brakes. All adjusted right. No leaking oil seals, newer looking shoes. I changed the glad hands out to 1/2 inch quick couplers. Nothing I haven’t done in the past. This trailer had a goofy valve on the blue side. Like a check valve release valve or something. This trailer grabs quick and releases fine. I’m not sure what is up I’ve never seen one like this. Does the air valve on the trailer air supply have a spring in it that pushes back against application pressure or something.
