Tony .. have you bled both bleeders on each caliper... are you sure you dont have a fitting loose... did you bleed the master first... you could have a bad master... a QT should do the whole job easy... thats one thing about using a vac bleeder.. you dont use pressure and it sucks in air and doesnt show leaks easily(no fluid leaking)

Bench bleed the master first, this can take a bit of time. Then gravity bleed the entire system starting with the farthest bleeder from the master cylinder. Go around the car several times. Apply the pedal to push the pistons out, do not pump it rapidly as this just airiates the fluid. Gravity bleed some more then with an assistant pressure bleed starting at the farthest bleeder first by applying pedal pressure, opening the bleeder than closing it before the pedal is released again.
I'm sure you know all this, sometimes we just need a reminder.

I had a similar issue when converting over a 71 Charger R/T from brake drums to the Wilwood disc's. Mind you this was a brand new kit. Figured it'd be an easy afternoon job since I've done the conversion many times before. BTW, I hate safety wire lol I put everything together, used a vacuum pump to bleed the brakes as always and no pedal. I figured there was air in the system so I kept bleeding and bleeding to no avail. I think I put close to 3 qt's through it. Figured I got a bad MC so I ordered another one. Still no help. On my 2nd day of trying to get some pedal pressure I pulled the wheels off, had a bud jump into the car and lifted him on the lift and planned on bleeding the brakes the old way. However this time around I used a small dead blow hammer and tapped on the calipers in hopes to dislodge any trapped air at the pistons. I remebered this trick when installing a Baiar disc brake system in a Mustang. I started on the right rear tapping the calipers with the dead blow while bleeding when I seen a burp of air come out of the line and he hollars down...I got pedal, not much and its soft, but I got pedal. A short time later the brakes worked like a million $$$. Just my

Based on your description, is your master cylinder LOWER than the calipers??

Bunch of info on the internet re using a 2lb residual valve when the MC is lower than the calipers. Among other things, that condition can cause flowback from the caliper, retracting the pistons, resulting in longer pedal travel.
A 2lb residual valve, used mainly to keep the flow of fluid from flowing back to the master cylinder from the calipers and brake lines in applications that have the lines and or calipers higher than the master cylinder.

Chris I will keep that in mind if I keep having issues. I did get the leaks stopped. Bone dry when I got home. So sitting for 24 hours it did not leak. Not to button it up and get them bled.
