Filling & Bleeding New Brake Lines ??

[Rack Man]

I am about ready to fill & bleed my new power brake system for the first time....I am wondering whats the best and easiest way to do that ?...I have heard of "Gravity" filling the lines but not really sure how to do that....do I gravity feed them one at a time or open all bleeder screws at the same time?

Also, I did not bench bleed my MC so I need to do that while its installed....that should'nt be too much trouble....but do I need to include the Prop valve when I bench bleed it?...Also, what about brake fluid?....DOT5 or DOT3?.....

Btw, this is a complete new CPP booster/MC kit with all new SS hard lines


Any insight would be greatly appreciated!
