you need to bleed the entire system, starting with the master cylinder, once you have all the air out of the master,, then you can do the brake lines themselves, if your booster was bad it would be sucking fluids into the booster itself,, the PCV valve has noting to do with what your describing , what your describing is air in the lines, you can borrow or rent a reverse order bleeder from parts stores like autozone,, or O reillys , also make sure your doing them in the corect order, you have to start with the rear passenger side, then to the rear drivers side, then back to the front passenger, and finally the front drivers side,, heres a short video of the tool I'm talking about that makes the job very easy http://www.youtube.com/user/scottykilmer...
