i don't understand what you are asking.

what does the static coefficient have to do with the question at all?

the reason locking the brakes on a car and skidding stops faster on dry pavement is because it maintains a constant maximum amount of friction between the tyres and the road. ABS won't let the tyres reach that maximum of drag and allows them to slide for fractions of a second (which is functionally no stopping force). hence longer stopping distances with ABS on dry pavement.

wet pavement introduces hydroplaning - locked up tyres equaling no friction.

but in all of these cases, we're discussing kinetic friction.
