Brake pedal goes most of the way to floor

[chargermick]

The brake pedal goes about 3/4 of the way to the floor before it starts to grab. This isn't terrible because the brakes do grab eventually, but it doesn't give you a real feeling of confidence in the brakes. Here's what I have done in the last year. 
SSBC front disc brake kit with new master cylinder
All new stainless brake lines
New wheel cylinders , shoes,
and spring kits in the rear
Bled the snot out of the system 3 times with a vac pump at each wheel
Had the brake booster rebuilt
I really thought that I was eliminating these kind of problems by replacing the whole braking system, but no such luck. Any ideas as to where to turn my attention to next?

Try adjusting the rear brake shoes out a tad.  That is what did it for me when I had that problem.

Is the master cylinder the right one?  Did it have a single master cylinder before?  Now a dual with the front disc.  Rod length could be wrong for the master cylinder?

I had that problem too, it ended up being that there were air bubbles in the lines.  I just bled them out thouroghly and they were fine.

did you bench bleed the master cylinder?

Thanks for all the help everyone. To answer your questions: yes I bench bled the master, bled the hell out of the system, adjusted the rod so that it is just short of the piston in the master, and adjusted the rear shoes. I'm beginning to think I got a bad master from SSBC.

I think your booster rod adjustment might be the problem....not out far enough & causing the excessive pedal travel.  Thses are the instructions from my rebuilt booster as well as the FSM instructions.   (step #4)   

Not very clear either way.
In the FSM they give a measurement for the rod but that is for the drum brake Midland-Ross booster & not the Bendix booster.....

Adjust the rear brakes & bleed again.
