Any way to bleed brake hydraulic lines through the master cylinder.

What is your question?

Need to bleed brake lines through the master cylinder if that's possible. Vechicle had no brake line leaks just need to put new master cylinder in. Suspect the bleed screws on the calipers are rust frozen in so bad loosening them will probably near impossible. Will the hydraulic lines bleed the little bit of air upward themselves through the master cylinder after I install it?
