2003 Expedition Brakes

I replaced the front brake pads on a 2003 Expedition. I shouldn't have, but did, loosen the break line to push the plungers back in. Now there is a lot of play in the break peddle.......
I tried bleeding all of the lines by having my girlfriend pump the brakes and hold the peddle down while I loosened the lines and then tightened as the peddle went down to the floor. Is this the proper technic?
The brake peddle still has a lot of "slack" in it. What else should I do?
PLEASE HELP>>>>>>

when you bleed your brakes that way you should open the bleeder screw located on the calipers instead of disconnecting any lines other wise you risk causing air to enter the system which seems to be what happened to you.the proper sequence for bleeding is to start at the wheel furthest away from the master cylinder. so follow this sequence,right rear, left rear,right front, left front.remember when you open up the bleeder screw hav your assistant press the pedal slowly and when the pedal is all the way down then close the bleeder screw.then your assistant can release the pedal once the bleeder screw is closed.do this at least twice at each wheel in the order i mntioned and this should purge all air from the system.
