The Cobra brakes have the traditional "star wheel" which automatically

backing up hills with a surge hitch. Surprisingly, the trailer shop
tech said there was no hole in the back plate for manually adjusting
the brakes.

My 17 year old Cobra axle does not have self-adjusting brakes (they are
manual adjust only), and the brakes released automatically if the
trailer was backed up. This feature - automatic release - is why Cobra
trailers have a wheel chock mounted on each fender: you are supposed to
chock the back of each wheel when you are using only the parking brake,
otherwise the trailer can turn in the wind.

My 3 year old Cobra axles has exactly the same braking system: no
automatic brake adjust (manual adjust only), and releases the brakes
when backing up.

I suspect all Cobras have the manual adjustment opening, but the trailer
tech missed it on your trailer.
