If pedal doesn't move booster is either bad or no vacuum being applied to booster

If your master cylinder was replaced make sure you do a good bench bleed on it. If that is good, bleed only in the following sequence:
Left rear inner
Left rear outer
Right rear inner
Right rear outer
Left front
Right front
If your brake pedal feels any sponginess repeat the procedure.
If you have to apply excessive pedal pressure you could have a stuck caliper or one is sluggish.
