1965 Dart front disc brake conversion low brake pedal

How on Earth would I know that when the car is where you are? You're going to have to exert yourself and actually look. I bring it up because sometimes there are slight variations in machining and tolerances in master cylinders and sometimes the pedal can slightly change positions. Just as an example, I replaced the master cylinder on my Ford truck several years ago. Upon initial test drive, it was fine. But the longer I drove it, the more I realized the front brakes were trying to lock down. I ended up slightly shortening the rod between the booster and master cylinder, as the new master cylinder's dimensions were slightly different and it was barely applying the front brakes sitting static. Although yours would be in the opposite direction, it's worth looking at. Unfortunately, since this is the internet, I cannot do that for you. I think some of them are adjustable and some are not.

From what I can see the rod is not adjustable. I thought maybe I was missing something. I think I will try an adjustable rod.
