...you can prevent fluid loss from the Master Cylinder, when reconnecting the car's brake lines by following these steps:

1) Mount the MC to the booster with Bleeder Hoses/Lines still in place.

2) Improvise a prop to hold the brake pedal depressed about an inch and a half (1.5"). This will prevent fluid loss when removing bleeder lines.

3) Reconnect the main brake lines, but leave slightly loose to do a final pedal bleed, as Cliff Pope suggests below, while tightening the connections.

A complete system bleeding is probably in order, since the results of the previous one are somewhat questionable.
