300tdi brakes problem

(1/4) > >>

BigBlueBeast:
I am having some scary issues with my little daisy, she is ok when the brakes are used regular during a journey, untill they aren't used for about 3 mins minimum, then the pedal can be pressed almost to the floor then a second pump works the brakes as normal. The vaccuum servo is ok, the brake pads and discs are all fine too. It has up near max on brake fluid, i just dont know what the hell it could be. I don't want to have to change the brake servo itself, so if there are any tests I can do, please let me know, or someone come HELP!!!!
Cheers. Craig

The vaccuum pump is sucking nicely, if you remove the pipe, and press the brakes, the pedal goes solid. Put it back on then the pedal is back to normal.
