Thanks so much for the excellent advice, as always, John.
I now know why the symptoms I described confused you (and me) so much.
Turns out, the park brake was jammed. I had disengaged it of course, but, as I was about to remove the hub, it occurred to me that I'd better check. Yep, the shoes were hard fast against the drum.
What I don't quite understand is why the other rear wheel was able to turn freely if the park brake was seized. Doesn't the park brake prevent the prop shaft from turning, thus braking both rear wheels?
Anyway, it is good to have been able to withdraw and check the half shafts and adjust the rear brakes in the process.
Now to overhaul the park brake.
Thanks once again, oh mighty Lord Rover. :)
