Installing new powermaster brake systems any tips on bleeding?

[GNX548]

I just got my new powermaster setup and am going to bleed the system. I have all new SS brake lines, new pressure regulator valve,new wheel cylinders and of course a new powermaster. So as you can see i have a big job. After looking it over, it said something about holding open the pressure regulator when bleeding??? Are they any tips someone could give me.Thanks

The way I do it is using a MityVac with brake bleeder kit...attach hose to bleeder screw...pump up the MityVac...then open bleeder
...do this on each wheel until no more bubbles...this way you don't have to have anyone pump the brake pedal...or worry about holding the button in on the combination valve...make sure to depressurize the system if you bleed this way...
