Is the pushrod length correct ? did you bench bleed the master cylinder before installing it ? otherwise i had a similar issue on mine when i converted to disc brakes, and on mine it needed much and thorough bleeding of the system to get all the trapped air out of the calipers, and i had to be very careful on how i operated the brake pedal while bleeding the system, in order to do it properly

I am still having issues on a total new install myself. Master cylinder must be bench bled, can still be done while in the car though. Rear shoes must be adjusted to almost touching on the rears. And like Jan said, much bleeding in the fronts. I have bled my fronts out many, many times, and still have a soft pedal. I will just periodically bleed the fronts until I have no air coming out of the fronts. Every time I put vacuum to them I get air bubbles. I bleed until they don't come out anymore, but still have a squishy pedal. After driving a little bit I try it again and again get air. Seems like maybe the fronts just hold a lot of air and it takes a lot to get it all out.

I think you'll find that you'll get a lot more help with your questions if you take the time to type it so people don't have to read it 5 times to figure out what you're asking. I just gave up after the second attempt.

Absolutely!
I enjoy helping out but if the poster doesn't take the time to structure a coherent question, why should I take the time to respond?

Was this a power brake car originally? I noticed you said replaced and not upgraded. If it wasn't power brakes before you might need to swap out the brake pedal and hanger for a power brake setup.
