View Full Version : Trailer brakes dragging only when hooked up to truck....Please help

My old breaking system would only operate under heavy breaking so I rebuilt it. Now they seem to over work. With the trailer unhooked and the tires jacked up each one spins freely when applying pressure to the surge break they all apply pressure and then release when pressure if removed from surge break (this would indicate to me all is working) My issue is when I hook up my boat and trailer it to the bay (about 20 miles) my trailer breaks are smoking hot. Any suggestions on where to start to resolve this would be great. Also my trailer when hooked up to my truck is very close to being level, and my hubs are not over tighten. Thank you,

Breaking system is UFP now part of Dexter dual axle disk breaks.
