If you need to do this now, and can't get to a vacuum type bleeder, sometimes this gets all the air out:

1.Fill up master cylinder and close lid
2.Pump,pump, pump, and pump the brake pedal
3.Uncover the master cylinder
4.Open bleeders (one at a time at first, starting with farthest from master)

If you have lots of air in the line, you may have to cycle through this a few times to get the fluid flowing. However once the fluid is flowing, gravity will work the fluid through the lines.

5.KEEP AN EYE ON THE FLUID LEVEL, you will have to top it off
6.Tighten bleeders and fill master to proper level

Also, tapping on the lines with a wrench can get the fluid flowing to push out air pockets.
