Did you make sure to have some free play in the brake pedal linkage? The master cylinder has to return completely to uncover the bleed port that lets the wheel cylinders push the fluid (and any trapped air) back into the master when the brake pedal is released. You can feel the free play in the pedal-it must move slightly before contacting the piston in the M/C.
You could also try jacking one end of the car as high as possible, then bleed that end, then do the other end the same way.
