MJ Dunn, I asked because we have moved from offering you free advice to costing you money.
I do however think you are headed in the right direction.

Replaced the master cylinder and everything works fine. It was a good experience for me. Thanks for all your help.

Take the old master cylinder apart. It should be assembled like this. The "valve seat" has to be installed first into the empty housing. If assembled in incorrect order the piston will not be allowed to return properly to it's stop and the fluid will not return to the master cylinder reservoir.
