Yep, I thought (was hoping) that was the problem, but I measured the bore size of my previous master, and it was 1 1/8", which I believe is the correct size. I then called Cardone for the bore size of the master that I currently have installed, and they said that it's 1 1/8".

I'm going to start isolating parts of the system today, starting with plugging the master, and seeing if the pedal stiffens up, that way I'll know if it's the booster/master, or something else, and I'll move around the system in that fashion, hopefully until I figure out the problem. If anyone has any suggestions, I'd be happy to hear them - I'm getting desperate! It's getting nice out, and I need my T/A to stop as well as it starts!
