There is some controversy on pumping the brakes the bleeding, verses pushing it down one time and bleeding. I see both sides.are the rear brakes adjusted? If not you will get no pedal. As a rule of thumb for me, I replace all rubber lines. Like said before, they may look good from the outside, but its like rust, it usually works from the inside out. It could also be a air lock. I have had that problem before. Just mash the he'll out of the pedal one good time and then bleed. This should dislodge the air if it is in the master cylinder. Too much pumping and at a fast rate will cause cavitation and making it almost impossible to bleed. Take time in doing this, and as mentioned make sure the calipers are not upside down.
