Feed back on the hot wheel problem: I have had the entire undercarriage, rims wheels, axles, brakes bearings checked. All ok, the problem appears to be with the electrical brake system either the controller, receiver or the ESC system. So both van and tug are off to a specialist centre where they can pin point the cause.
Thank you to all for the great suggestions.
My money would be on the ESC - The ALKO ESC fitted to my previous AVIDA was always faulty and activated savagely every time going left to the extent of stalling the Patrol - went back to manufacturer five times they couldn't fix it. We now have DEXTER ESC - chalk and cheese with no deactivating on dirt roads or to reverse.
ESC good idea, but they need to be installed by competent persons that are qualified technicians - not jungle bunnies in caravan manufacturers.

Hi Check if bearing cones are spinning in the drum.

Make sure the magnet is free and not sticking,one of my brake shoes got hotter than the other,from new.
It has taken a while to come back to this page, and probably way out of date or memory of those who replied in 2021. But in late September, after spending many dollars on mechanics etc, I found the fault through a process of elimination.
I disconnected every thing, the ESC, the electric brakes, to the connection of the offending wheel, to prove it was not mechanical. Went for a drive all good, reconnected electric brake, all good. I found it was the ESC, for some reason it was sending a mild signal to that one wheel brake, which just allowed the brake to apply minimal force. I unplugged the connection under the van, cleaned all the connections, and hey presto problem solved..
I did contact AL-KO for advise earlier in the piece which was a total waist of time, after 9 phone calls over 12 days, a women answers the phone, and says she is transferring you to their tech department, who, never answer the phone, leaving a message does nothing either.

Glad you got it sorted eventually mate, and thanks for letting us know.

Well done Klaus...It is well worth making a habit of touching the centre of each caravan / trailer wheel from time to time when pulled up for a rest break to test hub temps. Though always when the plan is to do so ensure no heavy braking is done while pulling up or the hubs may be hot from braking which defeats the purpose.
Making a habit of this may well save an expensive and inconvenient wheel bearing failure....

The magnet wasn't working properly from new.
