Dave...you're thinking of the clutch overcenter spring.
Brake pedal kick is ABS activation resulting from a wheel speed sensor not
seated deep enough. As the car slows to a stop the ABS loses signal on the
mis-adjusted sensor causing it to think that wheel is locked. At very slow speeds
the tranny ECU will interpret the loss of signal as three wheels slipping and
lock the center diff (automatic only) causing a binding of the driveline on
dry surfaces. The binding can be felt as a tire dragging or scuffing.
