Guys,
I am trying to bleed the brakes on the 56 Coronet and can't get any line pressure at the brake cylinders (rear) or the calipers (front). The car has front discs from fat man with new master cylinder from tuff stuff I think. I bled the cylinder before hooking the lines up, but for some reason it doesn't put any prssure to the brakes. The discs aren't even pushing against the rotor. What am I missing here? I have fluid to the rotors, and the master cylinder rod is pushed in a few inches when the brake peddle is pushed.

Should I go back and bleed the master cylinder again? I have a summit prop valve and new brake lines as well.

Thanks
