Did I miss something?

I changed out my old MC for a new 19mm per the Pelican article, and changed out my soft lines while I was at it. I've bled all 4 corners with a vacuum pump, but the pedal still goes to the floor. I cant get it to pump up at all, even depressing it multiple (~50) times.

Help?

First thing with Brakes is pad adjustment, Fronts are self adjusting but the rears need to be adjusted on both sides with an adjusting screw on either side of the calipers(venting clearance0.2 in). Pad adjustment is critical to proper brakes, I go by feel and adjust the pads so that if your tire was on you could not spin it 1 full turn if you tried. I always bleed from the farthest point of the master cylinder and so on.
Make sure you keep your resivor full. I use a tube from a bicycle, cut 12 inches on either side of the valve stem and then knot one side. Clamp the other end of the bicycle tube to your resivor and pump that baby up. You can now open the nipples on each caliper and bleed the whole system yourself, Filling the resivor and pumping your innertube as required.
