It is very difficult to diagnose this problem with the little bit of information you gave. If the brakes are drum brakes check to see if the brake cylinder is working and has no leaks, lift the rubber seals and make sure there are no leaks there, check the brake adjuster make sure that works okay. If everything works and you bled the brakes properly, then the problem is most likely is the master cylinder or the wheel cylinder.
While bleeding the brakes always make sure you check the master cylinder reservoir to make sure the fluid level is up so you do not get air in the brake lines. When bleeding the brakes did you have someone press down hard on the brake pedal hold the pressure on the brake pedal when opening the bleeder then push the brake pedal to the floor keep it there, until you tightened the bleeder, then pump the brakes up and hold it there, while you repeated the bleeding operation by opening the bleeder when the brake pedal go\'s to the floor keep the pedal down until you tighten the bleeder and then pump the brake pedal back up then check the fluid level in the reservoir, keep doing it until the brake fluid shows no sign of air.
If the brake pedal is pumping up during the bleeding process and you made sure you got all the air out of the brakes and then the pedal go\'s to the floor, make sure the fluid level is correct in the reservoir and the bleeder is closed tight and there are no leaks in the lines, wheel cylinder, brake cylinder the brake adjuster is working and master cylinder, and if you still have no brakes then it must be a defective piston in the wheel or brake cylinder, if there is a seal problem with the pistons you will not get any pressure to push the brake fluid. let me know how you are doing.
