Fluid is passing the seals both ways, if you cant see fluid then the rear seal is stopping it leaking out
Vacuum line will soften pedal but it shouldnt go to the floor
mmm so what do you think is the problem ?
I was very surprised that i couldn't build up a little bit of pressure from furious pumping .?
Because of that I wondered if the brake master cylinder slide was getting stuck at the end of its travel and not returning for the next pedal stroke ?

+1 For the master cylinder, but check the vacumn line to the servo also
I am pretty sure that there is something screwy with the vacuum system because it makes this peculia noise when the brakes fail but I can't think how the vacuum system could give pefect braking one minute and complete failure the next!.?
