BC lost vacuum from power assisted brake

Hi

So

I accidentally broke the master cylinder bleeder screw (only seen on 04 models)by over tightening it. yeah i am an idiot.

To get the screw out, i need to drill a hole first and then use easy out.

to drill a hole, i need clearance to get tools in. So i decided to remove the master cylinder from the brake booster and i didn't know that the booster is supposed to have VACUUM in it..sigh..dumb move

so now the vacuum is disrupted and gone...what effects are there if i just replace the bleeder screw and bleed my car and try to drive? will I be able to brake? or will the braking becoming significantly worse?

thanks guys

LOL... no worries, I've removed vacuum from the booster without any issues.
There is a vacuum line running to the upper intake manifold with a one-way valve.
When you start the car and vacuum builds-up in the intake, it'll restore your booster.
