If with the engine running and the pedal creeps down to the floor, then there is a fluid leak somewhere, check all pipes, unions, pistons etc, as well as the master cylinder to the servo area. If no leak found, get an assistant to press the brake pedal for you sand watch the fluid level in the master cylinder res.
When pumped it will go down slightly, but watch to see if it rises as the pedal falls or goes to the floor, suggesting an "internal" master cyl leak.
