Backing up a cobra trailer uphill. Is it safe ?

I have a steep driveway where I want to park my Cobra trailer.
Is it safe to backup the trailer up the incline ?
This means that the run-up brake will be completely compressed.
Can this be done without any damage to the mechanisme ?
Is my understanding correct that there is some kind of free-running mode on the brakes when pushing backwards ?

The brakes will open as the wheels start turning backwards, although the rod is completely compressed. No problem.

The answer should be self-evident since you're dealing with German Engineering, buddy!

No problem with the brakes if they are properly adjusted but I've encountered two situations where a trailer hitch popped off the ball damaging the rear of the tow vehicle when backing up a steep driveway.

It seems that some ball hitches don't like a large positive angle (trailer angling upwards with respect to the car) when combined with backing loads.

This led one owner to use an electric winch inside his garage to pull the trailer in without risking his car.

Wondering about the handbook. It calls for 290Km torque value. This translates to 213 FT LBS. Is this correct or does it translate to 65TT LBS? My brake stays applied when I back up and I am going to take the brakes apart and figure out why. Thanks

I can believe it, it's about what other axle nuts holding a cartridge bearing calls for.
Ranges go from ~140 ftlbs to over 200 ftlbs torque.
If they were an "old style" taper roller bearing, it's a lot less (more like 30 ftlbs).
