Pedal gets hard half way down, little front brakes

Brake lines were not taken off or empty during the time I was doing new bushings and ball joints. I did suck the master out and re fill with fresh fluid after I noticed the brakes weren’t working like they did. After that is when I bleed the brakes. The next day is when I cracked the lines on the master loose. Now that I think about it the air I saw when loosening the line on the master could have been because the first line I cracked it loose I didn’t have any pressure on the pedal because I wasn’t sure it would come loose. I retightened it and the. Had pressure on the second time I cracked it loose. The second line I had pressure on the pedals hen I initaly loosened it. The front wheels would turn by hand when brakes were depressed before adjusting the shoes. Afterwards they would not. I did not check how the rear wheels turned by hand. How would the distribution block play into this? Isnt it only to split fluid for front wheels and give a warning light if you loose pressure on either the front or rear lines? I did think about that and am going to ground out the wire to make sure that the wiring to it works properly. Then I will check shoe travel and rebleed then compare travel again and test drive.
Thanks
