'57 3200, just finished an install of front discs, new brake lines and new dual master cylinder / prop valve combo from CPP.

Now that everything is up and functioning - I've got about 3" of 'slop' before the brake pedal meets resistance / engages from the MC. The pedal would have approximately 7" of total travel, from all the way up to the floor - so I'm getting almost half way to the floor before getting any braking action.

I feel like it is possible the push rod that came with the MC is too short - I've backed the rod end off as far as possible, but there is still a too much travel in the pedal before engaging the MC.

Is there another adjustment point I'm missing? Anyone else had a similar issue?
