Why do my brakes not work after replacing power boost.

What is your question?

I own a 2004 duramax. I replaced the hydro boost because it was leaking out weep hole. After flushing power steering system as per directions I have no brakes. Brake pedal goes to floor with no resistance and can be pulled back with resistance.
