How old are your brake hoses ? These can collapse internally severely restricting fluid flow whist looking perfectly OK and serviceable on the outer surface of the hose. I would certainly consider stripping the master cylinder and replacing all the rubbers with new and at the same time checking the bore for any surface corrosion scoring etc. A rotating stone hone is available for cleaning up the bore - the bore can also be S/S sleeved or failing that, new master cylinders are available.
Note that the early 1948 to 1962 master cylinder had a 7/8" bore whereas the 1962 onwards had a 13/16" bore.
