My mate at Audi did a full brake fluid service and it has made absolutely no difference.
Could this problem be due to a lack of servo assist due to the following problem?:

My car has not been recalled but this could be due to the fact that it was an import and/or that it now has a private plate. Im not sure whether its worth giving Seat my chassis number so they can check if this needs changing.
May well be this, sounds interesting.
Will pop into seat somtime.
