Brake issues

[DCW2009]

I have a 1995 k1500 silverado i replaced my wheel cylinders and brake lines in the back and calipers, pads, and rotors up front and the master cylinder. when I push the brake pedal I hear air and it wont let me lock the tires up nor will it let me power brake it either it just pushes the truck so I unplugged the vacuum line from the booster and everything works fine anyone know what the issue might be

I know this might be a stupid question but did you get the master cylinder cap and rubber gasket put back on properly?

Yea I did

Do you hear or see the air at the master cylinder?
Is the pedal hard or soft and does it sink when constently pushed held in posistion?
Did you bleed the whole system when you were done?
