The possibility exists that the diaphram in your booster has a crack in it, and the pedal movement opens that crack allowing a vacuum leak.

If you want to check for a leak and don't want to use the usual WD40 or carb cleaner spray method into your booster, use starting fluid....
very gently, don't over do it.... it doesn't leave any residue.
