Can someone please tell me how to do this? (In very detailed directions please.) My booster went bad, so I bought a new booster and master cylinder. What all do I do? What do I bleed? How exactly do you bleed brakes? As you can tell, I don't know much. Any help would be greatly appreciated.
Thanks,
Kris

Do a search on this subject. There will be directions starting with bench bleading you master clyinder.

I would install everything the same way it came off.

Bench bleed the master first, when no air bubbles,
bolt it onto booster. hook up lines then bleed brakes from passenger rear first, driver rear, passenger front and driver front.
if you have a pressure meetering valve right under the master cylinder make sure the little rod sticking out of the back of it is held in with a small c-clamp while you bleed the brakes.
