i am far from being a brake expert. but i seem to remember being told that the booster does nothing but take some of the effort from you.

so.. if you pump them up firm with the motor running, it will be the same thing with the motor off..except you will be pumping them up firm-er..or it will take more effort to pump them up firm.

i bet you a VOODOO donut that it is simply air in the system.
