@Vic - please re-read my post...
>If you don't lock your wheels, your ABS system does *nothing at all*. It doesn't make any difference whatsoever to an unlocked wheel. So your stopping distance, if you don't lock the wheels, is absolutely 100% identical.
>If, however, you *do* lock the wheels, then the ABS does something: it unlocks the wheel. This means that you can get some retardation from the wheel, rather than just sliding across the road. This *dramatically* shortens the stopping distance.
That's exactly what I was saying!!!!!! ABS releases the brakes to allow the wheels to rotate, this allows them to regain tracktion. Then the brakes are reapplied until they lock again. Repeat as required. The same as with manual cadence braking, just much, much faster than a human can achieve. Obviously skidding to a stop takes longer than using ABS, but then braking just short of the the point of where the ABS is needed will be better still as your brakes will never be released (at that point you are not slowing down as your brakes are not applied).
>Perhaps. But ABS isn't there for when you do everything completely right - it's there to pick up the pieces when you make a mistake. Have you ever made a mistake? I certainly have
I beleive that I said ABS had saved the front end on my car. I'm human (last time I chekced) so yes I make mistakes.
>Even imagining that ABS might generate grip that isn't there shows just how little you understand the technology.
Again, that is exactly what I was saying. When you try to stop on sheet ice the ABS works perfectly, but the the grip just an't there for it to be efective. And this can happen even at tiny speeds. I never said it would generate grip. In fact I said exactly the opposite.
What I said is that correct winter tyres help more in the winter than relying on ABS to stop you...
So yes, I do have an inderstanding of how it works, and I also know that if I ever use it (not often) then it means I have put myself into a stupid situation where I've had to jam the brakes on too hard.
