I adjusted the brakes on my Cobra trailer according to the directions

Cobra.
On the first test drive, the right brake drum got very hot in a few miles
(about
240 deg F); the left brake drum got up to about 125 deg F.

Neither drum seems to be dragging when I jack up the wheel and spin it. I
backed
off the right drum about 8-10 clicks, which reduced the temperature to
175
deg f
(but it was shorter drive). The brake handle still comes up to the
correct
position.

I'll back off the hot drum another 8 clicks, and see if it still gets
hot,
but I'm
wondering if I'm missing something here. Does anyone know why it's
getting
so hot
if it isn't dragging?

Just a couple of thoughts.
Are the wheel bearings adjusted correctly and greased?
On the brake rod linkage, is the 1mm gap there with the brake off?
