Same thing as this gentlemans problem

Same thing as this gentlemans problem. All new rotors, calipers, and pads on front. Replaced booster and master cylinder, replaced rear pads and everything else was okay. Bench bleed the master cylinder as according to the instructions with it. I am a mechanic of heavy equipment so I do know what to do with it. But the brakes work good in the back but no or little movement on the front. There is an ABS box every line goes to but I dont see it when connected with computer. Can unplug ABS module or whatever it is and do not get any codes on computer. Thought this was going to be an easy turn around for a family member but has turned into a nightmare. All this and another friend wants me to do his but now I am thinking of not doing this. Please help!
