brake problem

[JSeery]

"Only way I can bleed all air out, is to unbolt from back plates, whilst still attached to hoses, G clamp across ends of cylinders to prevent pistons popping out, and 'manipulating' them into such a position as to get all air out."

Brian, that is not a usable part or bleeding process. I know you were just attempting to get it bleed, but over time you don't want to be disassembling the whole brake system every time in needs to be bleed. You need good quality wheel cylinders, but no idea where they would come from in England!
