Sounds like you somehow lost the vacuum supply to the booster in this process.

You popped the line off or did it fall off from a backfire or something?
Have you checked for engine vacuum at the brake booster check valve?

It didn't back fire, it was strange, the defrost was on from the night before other than that nothing.

Of course there is a way to get it back, but you have to find out if you have engine vacuum at the brake booster check valve first. Lines usually don't pop off for no reason.

Did you take the valve out of the brake booster and check for vaccum at the end of the valve with the hose still connected to it? The engine has to be running of course.

Re: brakes

So you pulled the big hose off the check valve and it sucked on your finger?
