Power Brake Oddity

My panel has a dual diaphragm power brake booster. Works great BUT...

Whenever I turn off the engine with my foot on the brake, the pedal remains down about 1/2-inch which often leaves my brake lights on. During normal driving the pedal always returns fully. It has an auxiliary return spring - I could make it stronger, but I'm reluctant because I don't want it adding to my pedal pressure.

Any suggestions?
