Ok ive replaced both calipers and front brake lines. Now when I press the pedal it goes half way till it gets tight. From time to time it will be tight and it feels like a brake is holding. So my question is this: could this be my master cylinder, vac booster, or a collapsed rear brake line?

Why did you replace everything to begin with?
Is the fluid the correct level and did you bleed them? You may need to bleed them again or atleast I would before replacing the master.

Calipers were bad and brake lines collapsed

Calipers can be a pain in the ass some times, recheck the connections, try bleeding them again, make sure the rear brakes are good and adjusted properly, if they are off it will take more pedal.
