Pressure bleeding? what is that? is it like bleeding the lines while you get yelled at?
Fill up the reservior and instead of putting the cap on it, hook up the pressure bleeder. Pressurize the reservior, then open the bleeder screws one at a time and let all the air and old fluid flow. When new, clean fluid is running out of it, close the bleeder, top off the reservior, pressurize it again, and move to the next bleeder.
The problem with the old pump and hold method is that it can sometimes break big air bubbles into thousands of tiny air bubbles. The fluid is constantly moving back and forth through the lines as it's working it's way out . . . it's kind of a "Three Steps Forward, Two Steps Back" deal. Sometimes the tiny air bubbles hang up in the lines and the fluid works it's way around them. With pressure bleeding, fluid moves from the reservior straight through the master cylinder, brake lines and out the bleeders at the wheel cylinders.
To improvise a pressure bleeder, get a spare reservior cap, drill a hole in the top of it and insert a valve stem in it. I've had pretty good luck just pressing them into the hole, but I guess it wouldn't hurt to put a little sealer of some kind on it. If it doesn't seal good on reservior, you may have to find a flat O-ring of some kind or cut out a piece of rubber to make a seal. Once you have this new cap with the valve stem sealed to the top of the reservior, pump in just a little pressure on the reservior (it doesn't take much pressure . . . too much will bust the reservior).
The hardest part is making sure you don't run the reservior dry and pump air back into the master cylinder. If you do a real good job with your improvised pressure system, this can be a one man job . . . but if you have someone to run the pump and watch the fluid level, you can get the job done as fast as you can run around the car and open and close the bleeders even if your pressure system leaks a little.
By the way, brake fluid should be CHANGED every couple of years. The brake fluid reservior is not sealed from the atmosphere and the fluid will absorb water from the air. This water leads to rust, corosion, etc. in the internal workings of the brake's hydraulic system if it's left there. Once you have everything working right, if you pressure bleed the system every couple of years you'll get rid of the water in the old fluid and you're system will work much better, much longer.
