rbohm said:a power brake booster doesnt decrease stopping distances, or increase braking efficiency, so much as it multiplys the force you put on the brake pedal which makes it easier to get the line pressure up on a disc brake system. you can apply the same pedal pressure without a power booster, it is just alot harder to do so, and that is where the illusion of shorter stopping distances comes in with a power booster.
While in theory I agree, you're not factoring in "time for the human factor." It takes a certain amount of time for you to physically apply the pressure to stop fast.
If the pedal is harder to push, it will take you a little longer to depress it as hard as a car with a booster. I'm confident side by side you will find the booster car will stop faster just because it has immediate pressure when depressed.
