If you wanna know why it does that, its because when the engine is running you have a vacuum being pulled on the servo which makes it easier to push the brake pedal when the engine is running meaning you don't have to press so hard to apply the brakes.
When its off the vacuum from the engine is no longer created meaning that the servo has no vacuum. This makes the pedal stiff after a few pumps. If the pedal is still light after a few pumps when the engine is off. [u][b]THEN WORRY[/b][/u] because it usually means your leaking brake fluid, lol.
