Thank you for sharing that you are human, too. As a newbie who sometimes gets quite ham-handed with the work on my Sprite, it is comforting to know that even the more experienced folks on this forum are subject to human error as well. Sometimes when I post something that has gone awry, I often wonder "I'll bet these folks are just going to be shaking their heads behind their computers". It hasn't happened, though, and for that I'm definitely grateful to everyone who has chimed in each time I've bumped into a problem, which happens often!

Coming back to the Master Cylinder - got it reinstalled. I use DOT5 which does tend to foam a bit. Likewise there is the ever present issue of the hose being higher than the MC. So, I bleed it by holding it higher than the hose, bleeding through the MC, Spread it over a few days and must say there were satisfying bubbles each time. It is now re-installed and, I don't think I have never had as hard a pedal.
