Ok well im gonna do 1 more post to get some opinions here. To bring everyone up to speed.
1989 Mustang. I put 73 MM calipers, Russel Stainless lines front and back, Slotted rotors. Well i put all this on with my stock M/C and could not get pedal. So i was like maybe my master cyl just cant keep up with more volume. So i got a 93 cobra M/C. Still i have to pump it about 6-10 times to get a pedal...then let off the pedal and 10 seconds later push it again and goes to floor. SOOO i trailer the car to a old tech that is mainly a chevy guy and does some work in his spare time... Well lets put it this way...1 month later i have bought another 93 CobraM/C and another caliper becuase 1 was leaking... And let me put it this way I trailered the car back to my parents garage yesterday.... At this point the car is about to be pushed into a lake. My current ideas. Im going to get to plugs and plug the master cyl. and make sure i get pedal. If i get pedal im going to see if i can hook up 1 line and and get pedal. Then i can narrow it down to front or back problem. Also if i narrow it down well im not sure what the problem could be besides maybe the brake lines. ?? I dont know anymore, i do know im never doing brakes again. Any ideas. OHH and let me answer these questions now... NO there are no leaks and yes the system has been bleed about 500 times and yes the M/C was bench bleed.

Thanks

did you bench bleed the master cylinder before you hooked up the lines.

Yes, I see I missed that last part, **** happens

I HAD THE SAME PROBLEM WHEN I PUT AN AFTERMARKET FRONT END UNDER MY CAR..
NEW EVERYTHING...
IF YOU PUT THE FRONT CALIPERS ON THE WRONG SIDE, WHICH IS POSSIBLE TOO DO.
YOU WILL NEVER HAVE BRAKES BECAUSE AIR WILL STAY INSIDE THE CALIPER,NO MATTER HOW MANY BOTTLE OF BRAKE FLUID YOU GO THROUGH!!!
JUST TRY SWAPPING THE FRONT CALIPERS FROM LEFT TO THE RIGHT SIDE, AND I BET IT WILL FIX YOUR PROBLEM.. IF IT DOESNT,, IT IS POSSIBLE TO GET A NEW MASTER CYLINDER THAT IS BAD..BUT NOT LIKELY.
TRY THAT AND SEE IF IT FIXES YOUR PROBLEM.

OHH YEAH, ALWAYS START BLEEDING AT THE ONE THAT IS THE FURTHEST FROM THE MASTER CYLINDER!! SOMETIMES IT TAKES A WHILE TO GET ALL THE AIR OUT.. IF YOU DIDNT KNOW THAT, JUST TRYING TO HELP..

Did you check to see if your brake booster is good ??? I never heard of a problem like this going on for so long , I normally use a one man bleader kit / vacume pump I got a harbor freight for 10 dollars it works really good

No clue if its bad but from what ive asked before...if it is bad i would still have a brake pedal just it would be hard
