your using a vacuum bleeder, toss that junk, get a buddy to pump the pedal till theres some pressure then have him hold the pedal down YOU break open the bleeder, air will squirt out, then CLOSE the bleeder, and tell buddy to pump again
BUDDY MUST NOT LET THE PEDAL OFF THE FLOOR TILL YOU TELL HIM TO
i have never in my life even when replacing an entire system used more than 1/2 quart of fluid, but that was wheel cylinders master lines and all
thats what i was doing, all i got was air air and more air...
