I got a new brake master cylinder and brake calibers n bleed out the whole system no leaks n brakes still don't work
 
what does "brakes still dont work" mean? Does the pedal go to the floor or do you have a hard pedal and it wont stop or something else? Did you bench bleed the master? Did you bleed the rear brakes?

you checked the rear wheel cylinders by looking under the outter rubber dirt seal to make sure there is no leak? Are you using a pressure bleeder, if not what method are you using? If no leaks and you are sure you correctly bled the system I would suspect you were given a bad master cylinder.
