Ok. By allowing the master to bleed dry, you have introduced air back into the system.
What I would do is get two clean plastic bottles and fill them about a third of the way with new fluid. Puncture a hole in the top of the bottles and insert a 5/16 or 3/8 vacuum hose into each bottle until the end is submerged in the brake fluid. Attach each hose to the bleeder screw on the rear brakes, crack the bleeders open and work the pedal a few times.
You should have a helper for this, so the helper can observe the bottles for air bubbles. When there are no more bubbles, hold the pedal down and tighten the bleeders. Then repeat the process on the front.
One thing, with the power booster attached, the pedal will naturally sink closer to the floor when stepped on.
I would also double check the adjustment on the rear brakes. While turning the rear wheels by hand, you should hear the drums moving across the shoes basically full time. Yanking down on the back on the wheel should get you right around two revolutions. And more, and the brakes aren't properly adjusted. This will cause the pedal to need more travel before brake engagement.
