Leaking BPMV on a 2000 C5
I experienced an almost sudden case where the brake pedal would go all the way to the floor. Added brake fluid, and with about 5 pumps was able to drive home and stop when necessary. Looking at where the fluid went, I pressurized the master cylinder with my Motive bleeder and heard hissing coming from the BPMV.
Cannot determine exactly where it is leaking, but it appears to be from one of the "plugs" on the bottom possibly. It appears these units are very expensive if they can be located. Looking for ideas please!
Maybe Bill Curley has an idea? The car went thru a pint of brake fluid in about 5 stops, thus, good leak, the Motive went from 5 PSI to zero in about 1 minute...

Unless you PIN POINT the exact location of the leak, its very difficult to provide giudance.
Get a mirror and a flashlight and figure exactly where and what is leaking.
Get a picture of the leak point if it is possible.
