401 rear drums

[innellan House]

I am providing a follow up to the question I posed in 2014. The problem was sorted some years ago when the penny dropped that a previous owner had inadvertently swapped the rear backplates (the backplates are LH and RH designated). If the are mounted incorrectly, the trailing shoe cannot make contact with the drum, and the handbrake cannot be adjusted to maximum effect. I thank Mr Geoff Dowdle for the light bulb moment.
