OK so I pressure bled the brakes and now everything is hunky dory. Perhaps the air in the brake lines was causing the pressure booster some trouble, I'm not sure but it stops when I tell it too now which is nice. My friends would really make fun of me if I had to open the hood and press that big red switch everytime I wanted to stop my car

Thanks for the advice though. I was actually close to trying to take the master cylinder and brake booster apart which would have been bad. Usually, it is probably something simple!
