problem bleeding back brakes

Some of the problems:
Valve is jammed
flares on the lines are incorrect
blocked line
If you had a pedal before and now there is no fluid,its all up front my friend
Take a hammer and tap the valve to see if it unseats,what is the valve off of? New or used? Does it have a sensor in it,?mrmopartech
