Default brake issue? they wont work

so i accidentally let the master cylinder go dry when i was changing my brake fluid and putting on cobra brakes and i can't get them to work. i bled the master cylinder and then started at the back brakes and bled all the old fluid out until there was clean fluid(no air) then the fronts (also no air) and i did this twice and i still have no brakes. the pedal goes down to the floor and then barley works i have to press really hard.

what am i doing wrong?

Repeat entire process?

If you bled everything correctly there should be no reason for the brakes not to work.

_____

You said you did it twice. Did you bleed the master cylinder twice?
