I hope someone can help!!

I can't figure out why I have no brakes!
I replaced the front and back brakes. Put new calipers on. I broke a brake line while trying to bleed them, so i replaced that. I bled the brakes again, but there was no brake after that. So i replaced the master cylinder, and rebled, but still no brakes!
There is no brake light on. other than the ABS which was already on way before even taking the brakes apart to replace them.
The master cylinder is not visibly leaking.
is a vacuum booster the same as a vacuum booster.
