Brake pedal travel

;)My 91 has always had good brakes,but I thought that the brake pedal went down to far ( it had new rotors,and calipers when I bought back in Dec. 2013). It was warm today ( middle 70's ),and I was checking under the hood,and found a vacuum line that was really loose.You could move it back and fourth with your finger. no clamp. I traced it back to what I think is the brake booster.So replaced it with a new hose. Started it up ,drove around the block,and noticed that the brake pedal seemed to only go down about half of what it was. Now is this just my imagination or did replacing this line have that much affect on the pedal travel ? (tried to load a pic,but would not work for me.)
