start the car press the brake pedal. see how easy it is and how far down it goes.
I believe it's 1-press pedal until it's "hard" 2-then while holding said pedal, start car. 3-pedal should drop maybe an inch or so.
I did do that and the pedal did go down a bit after I started it. A weird thing I noticed is when I hold the brake pedal down hard and rev the engine, I could feel the pedal go up and down about 1/4" as I was varying the throddle. The vacume changes with throddle opening, but I never noticed that before.
