Hi Dan,
On the early rear brakes, there are 2 steel pistons in the hydraulic wheel
cylinder, with a point of the lever between them. If all is free, when you
pull the lever with the brake cable, it spreads these 2 pistons and applies
the brakes on the rear wheels mechanically. Really works well if all is
free and the correct sequence of adjusting is adhered to. The biggest
problem is the steel pistons in the aluminum casting wheel cylinder, sorta
corrode permanently to each other. Not usually worth rebuilding, just get
new ones. Costs more to sleeve them than new ones do.
Morris Minors had this setup for their entire 25 year production run.
