The valve corrects the wheels "quick-twitch" which is a one-time jerk motion of the wheel when the brakes are applied. There is another problem: it's induced at higher speeds and is a pronounced shaking of the wheel when the the brakes are lightly or moderately stepped on. It feels like warped rotors but that's not the problem. Wish BMW would admit there's a problem; that would go a long way to solving it.
