Long Travel Soft Brake Pedal

Another thing I should mention is I first bolted Dana rear in with 10.7 rear disc, retained stock kelsey hayes front disc, pressure bled entire system, and test drove. Thats when I first saw long pedal travel spongy brake feel. So with all the stock known to work front brakes in place, existing 15/16 master cylinder that had been on for a year, that is when I first saw the issue. But wrote it off as maybe didn't bleed enough. Car could not lock up tires and was slow to stop. Most likely if I bolt tires back on car its likely be the same way.

Doctor Diff seemed to suggest today maybe get a rear caliper tool, rotate rear caliper back in, activate release packing brake several times, then rebleed again? I told him I did hook up and apply and release parking brake before bleeding? But maybe not enough and air is stuck in there?

But I might be forced to start blocking/plugging brake lines, clamping caliper pistons ect and narrowing issue down. But air stuck in rear brakes somewhere for some reason is suspect.
