I cannot get the air out of my brake lines

the master cylinder when replaced SHOULD be bench bled before installing on the vehicle. try a power bleeder

already used a power bleeder and bench bled all of them

start at right rear, left rear,right front left front. if air is till in system thereis a loose line or connection or bleedervalve not seating.

i thought of that too but if the bleeder valve is leaking or the connection is loose wouldnt there be a leak cause i dont see any leaks at all

not neccessarily, it may be leaking just a tiny bit. I you had brakes before and just replaced the master then either the master is bad or it's got air in it.if you have put new brake lines in by using compression fittings instead of a regular flare with a connector that may very well be your problem.
