On top of the vacuum booster there is a VENT with some felt like packing in it as a filter. If the vent becomes plugged then the pedal will not release because the vacuum piston can not return. Also, INSIDEof the booster is a vacuum hose. If it gets kinked or is not installed right then that could cause the problem too.
