Help, one brake not letting go

[sinjin]

The trailer is a dual axle 2009 28' International. It was parked for a couple of months and this past week we changed out the Tires and Wheels (mich 225/75/R 16 MS/2 and Sendel wheels*). First trial today and the driver's side front tire on the trailer got hot. Really, really hot.

Just took off the wheel, and the hub spins freely if the TV is off. When the TV is on it appears like the trailer brake immediately engages (hub no spinny), sometimes. Turn off/turn on, spins or not

Any suggestions/ideas for further trouble-shooting? We are supposed to leave for 2 months a week from tomorrow.

*Thanks for all the threads on wheels and tires all. Kept me up for days reading thru all that.

Check it with a volt meter at the wires that go to the magnet. There should be no voltage there unless the brake controller is telling it to put on the brakes. I do not know why only one brake is locking up, if there is voltage there they all should lock up. Also have you pulled the brake drum and checked for broken springs?

i saw this happen on a car trailer. it turned out to be a bad ground wire. i my case, it was somewhere in the umbilical cord.

Thanks. After adjusting all the brakes, it seems to have gone away???
