Are you sure the ball races and bearings are okay?
We had this happen to a club trailer a couple of years
ago (not a Cobra but the same Alko hub that Cobra uses).
The wheels didn't quite fall off but they didn't half
graunch and on closer inspection the ball races were
shot and some of the balls were square, all the grease
having boiled/burnt off. The brake shoes also needed
replacing.

Let me put it this way, I definetly didn't leave the
house with the
hand brake on. Where I have to hook up at the house
I must pull the
trailer about 5' to my truck. So I know it rolled
free. At some
point on the freeway (about 15 miles from home) traffic
slowed to
about 10 mph and some guy pulled up next and gave me
the finger point
at the trailer and some other gestures. There was somke
comming from
the right wheel and tire, the brake drums were so hot
it melted my
plastic hub caps. The brake handle was in the up position
at this
time. I'm very consious about the brake handle when
hooking up and in
transit, I'm assuming that upon leaving my driveway
and making a
u-turn down the street it might have pulled the break
away cable and
set the hand brake and pulling up in front of the house
I should have
checked it again.
I (thanks to the guy that I oue at least a 12 pack
of beer or more)
caught the problem before it destroyed the bearings,
races and
spindles. The tire was hotter than hell and if I had
of had a tire
catch on fire I'd have been calling Costello on Monday
(got a fire
extingusher now)

Anybody know where to source Cobra trailer brake shoes,
return springs
& grease seals.

We didn't drive with the hand brake on, did we?
