Late Minor 8" (Lockheed); Wolseley 1500 9" (Lockheed); and Riley 1.5 9" (Girling).
I'm planning to drive Fenchurch for a bit on the standard brakes, then try out the others and see which I prefer. Both types are theoretically an easy bolt-on upgrade, you don't need to remove the pressure retention valve from the master cylinder or fit a remote fluid reservoir, and they have the correct stud spacing for standard Minor wheels. In theory the Rileys should have the most resistance to fading, but the Wolseleys ought to give a lighter pedal because the wheel cylinders have larger bores.
Relined (exchange) shoes for the Wolseleys and the Rileys are roughly the same price, but they're both more expensive than a new set of standard Minor shoes.

Interestingly the friction material on the Wolseley shoes looks very different to that on the Rileys (not just the colour but the texture is different too).
New Old Stock or rebuilt Riley wheel cylinders seem to be very expensive compared to new Minor ones. New Wolseley cylinders aren't terribly cheap either, but the Wolseley backplates can apparently be modified to accept Minor cylinders instead.
