Morgan have a legacy of poor handbrakes when rear discs are involved. Even relatively new Plus Fours required careful handbrake cable routing to work effectively although I believe there have been recent upgrades to improve. This issue is not new of course, Jensen offered all round disc brakes (one of the first) on their CV8 in the early 60's but handbrake action was rubbish despite or maybe because of a dedicated mechanically operated caliper. Strangely our F54 Mini with humble single piston floating rear calipers has massive hill hold capabilities. I attribute this to the electric handbrakes powerful geared motor pulling cable equivalent to Gorilla with six foot pole
I have often typed that the early Lotus Elan was the first car I lusted after, though it too had rear discs and tiny handbrake pads, from a dull memory I think Jag were much the same, if you want a handbrake design that works with a disc brake set-up, then Porsche ever used a disc/drum set-up where the disc runs around the outside of the drum, a bit like a top hat, shoes living inside the drum as the norm, calliper acting on the disc... Simples...??
