Loosen the tube at the end of the master cyl. Push the pedal & see if you have pressure coming out of the line. If you didn't bench bleed the MC you may just be pushing air back & forth. Make sure you have a small amount of free play in the push rod in the MC. If it is to long it won't let the piston come back to open the port. Like the guys have said, tighten the wheel adjustments till each one is heavy drag. If you try to back them off till there is no drag it may be to far as new shoes will drag some till they are broken in/seated. Usually about 4-5 notches from heavy drag.
