What do you find strange about the brake design? They are, on this one, a perfectly standard 1940s Girling design.
In my experience, I have never had serious* problems with the brakes on any of the Landrovers I have owned over the last fifty years.
I suggest that a lot of the problems stem from unfamiliarity by suppliers, mechanics and owners with drum brakes and the assumptions that are implicit in these brakes and with the changing standards with threads and fittings over the years since these were first made.

*Serious = where the solution is not fairly obvious or not easy to apply.
