One thing that has not been suggested is an old mechanic's trick (I'm
the old mechanic in this instance).
Use a pair of vice grips to gently pinch off one of the brake flex
hoses. (be careful to just squeeze the hose sufficiently to block the
flow.) Pump the brake pedal (not to vigorously) until you have a solid
pedal then have an assistant release the vice grips. If you do this on
each of the 3 brake hoses you will be able to determine which of the
wheel cylinders LF RF or rear is the cause of the problem. In my
experience it is unlikely that the master cylinder is the cause.

Thank you to everyone for their advice.
I will try applying the handbrake and slackening off front cylinders
next
time.
If that's not successful, I think a master cylinder rebuild is on the
cards.
Did anyone ever try applying some plumbers tape around the bleed screw
threads, to prevent air intake when the screw is slackened for bleeding?
Thanks again.
