        Thanks for all the informed replies. I very much appreciate the =
advice.  I did source hydraulic assembly grease form British Parts =
Northwest and will attempt to rebuild the master, and if that fails to =
repair the problem, I=E2=80=99ll source a new one.  This is kind of one =
of those =E2=80=9CThe journey is more important the destination=E2=80=9D =
projects while I=E2=80=99m sticking around the house
        The master cylinder that I had totally fail had been re-sleeved =
as part of the original rebuild process.  We are fortunate to have an =
array of options in repairing our old Triumph cars. In watching =
automobile restoration shows, Im amazed at the lengths and expense that =
restorers have to go to get replacement parts.  In most cases we are =
only a phone call (mouse click) away from a part.
        After the m/c rebuild is finished I'll have caught up with the =
necessary maintenance on my cars and will move on to unnecessary =
maintenance.
        Thanks again all for the help and suggestions. Stay safe.
        Best,
