OK....heres the story.
I changed out the disc brakes on my Mustang 2 front end from the 9" Mustang rotors to the 11" Granada rotors with GM Metric calipers, new brackets, etc. When switching over the brake lines, I did not drain down the Master Cylinder too low as far as I know. I bled the new brakes / no air in the lines, however, I cannot get the pedal pressure to come back up. Do I need to remove the Master Cylinder and bench bleed it or do I have another problem ? Master cylinder and booster are off a T-Bird, and worked fine before I started this adventure. All suggestions appreciated
