travel on brake pedal?

1997 polo auto 1400cc. I have to much travel on the brake pedal. had all the brakes looked at but the problem is still there, I used to be a mechanic some years ago and I do know about brakes, once I ajusted the bar from the pedal to the servo on a Golf it had a thread on so it could be ajusted, is there one on this car? paul.
