Chris,
I missed seeing you at Cordele.

As Matt said, the previous owner of his trailer left the hand brake
on, and parked outside in the North Carolina rain and humidity for a
long time, the brakes seized. Backing off the star adjusters will
hopefully work. If not, you might end up having to take a torch to
the drum to try and break the grip that the rust has on the shoes.
Big hammer and a torch. Maybe. Get professional help!

Before seeing that trailer end up with locked brakes, I didn't set my
hand brake. After seeing the trouble the previous owner went through
and the expense of finally getting it fixed, I NEVER set my hand brake
for more than a few hours. Now, I just use the hand brake when
maneuvering the trailer on a slight slope for a few inches as I
connect it to the car. When I have the trailer where I want it, I'll
chock it and tie it down. But I'm not setting the hand brake!

Good luck!
