I've missed a few of the email responses as well as the original but
here is a little note.
A fellow member of the Delaware Valley Triumphs has had a 2-year brake
problem with his system. After bleeding pedal would be hard and then a
day later, soft with no lose of fluid.. EVERYTHING on the entire brake
system was replaced new! Finally, after 2 years of going crazythe
master cylinder was again replaced with a new unit. Finally the brake
system worked properly. It seems after talking to his favorite parts
supplier(who will remain annonymous) There was a run of bad master
cylinders and he originally had purchased a bad brand new master
cylinder.
Good luck,
