No pedal after bleeding brakes
If you dont have a leak, and if it has a master cylinder andits good, go to auto zone and get one of those self bleeders. Hook it up to the bleeder at wheel and pump pedal until brake fluid is at least half way in the cup. Do that to each wheel At least =youll know that the air is gone before you look elswhere. If the master cyl is bad it could be pumping back and forth in the master cyl thus not pumping to the wheels.
