When I bled the system the second time I did both the pedal and pressure. I no doubt introduced air into the system when I removed the reservoir. When I removed the reservoir I simply loosened the small hose clamps below the reservoir and disconnected the reservoir there, then plugged the lines there to keep debris from getting into the lines, and that's all that I did. The brake fluid remained in the lines from the reservoir tubes on down.
I sure don't like the idea of buying another master cylinder again as I really only got ~ 6-10 months use out of the one installed, but I guess it's sounding like that is the issue?? Any other ideas?
