ok who has expriences taking out the brake booster, speak up. After talking with extremeRS, we figured out the booster went bad. i can't suck or blow through that vacuum line, but I can when I disconnect it from the brake booster.

edit* now we think it may be the cylinder. Because when I take off the vacuum line from the booster, i can hear a gush of air coming out from where the line hooks up to the booster. Anyone else have any insight?
