I did notice the fluid leaking when I got home, it must have been a very small leak, but it must have flung off the inner wheel barrel during driving, so small, but enough to drop the brake fluid in the master cylinder over a 2-3 day period including the drive to Daytona (3 hours). After I tightened it up and did a bleed, I can't recall if an unusual amount of bubbles came out or not. The only symptom I really noticed was a firm pedal on application, but it would slowly sink down if I kept pressing it hard after I came to a stop. Reading the various Cayman threads had me convinced it was all in my head
