That is how I've always done them. Just go slow and steady with it.

Will need to remove the master brake cylinder from the booster to bleed the master cylinder properly. Use an old push rod or something that is long and has a round point, when bench bleeding your brake master cylinder. Make the master cylinder reservoir is about 3/4 full of clean brake fluid, and the two rubber hose coming out of the the port holes on master cylinder are submersed in the brake fluid during the whole bench bled process. Push in the piston on master cylinder, till it bottoms out, there should be no air coming out of the hoses when you have completed bench bleed process. Process should take about 1.5 hours.

Here is the master bleeding section: http://www.classicperform.com/TechBook/BrakeBleed.htm

correct, and when the master cylinder has been installed in the vehicle, bleed and flush out the brake lines.
