Tryed it and you're right the pedal does judder and no skid on a wet road. Worked at 30mph and 50ish.
I sometimes get the ABS activating even from 10 - 20mph and not under heavy braking ie, slowing smoothly for traffic islands and lights.
Is this normal?
Just so you know: Std wheels with new Pirelli tyres on front and 5-6mm worth of Continentals on rear. New front pads and disks, seemed to get this since they were fitted (about 5 months ago)

I hate ABS and there is no solid evidence to say you stop quicker (was it Fifth Gear that done these tests? anyway 70% of the cars with there abs disabled stopped quicker)
I mainly agree with the above quote though.

I can recolate a couple of times in the past where even I've (and I consider myself a more than competent driver) braked hard for one reason or another (usually someone running into the road or a car pulling out and not accelerating). And I can feel the ABS click in, and I'm telling myself
"Get off the pedal, get off the pedal"
And I do, but in those few car lengths where the ABS has been focused on keeping me going in a straight line, without ABS I would have gone several bus lengths.
Those who say ABS is a hinderance have never been in a situation where they've missed it.
You can bring up the point "what about when cars didn't have ABS"... Well sure, but did you ever drive a 200bhp car without ABS back in the day???
How many cars 10-15 years ago were going around that did 0-60 in 6 seconds... Not that many.
Yeah my cup, not quite 200 horses, but darn close.
The facts that something is true at some point in time doesn't continue to make it true.
Yes it is a fact that early ABS-equipped cars had a worse crash record that the same models not fitted with ABS.
But the technology has changed.
Those early cars had single- or at best dual-channel ABS. When ANY wheels locked the braking pressure was reduced on ALL wheels. This created quite scary situations where it seemed the brakes had failed, you were pressing the pedal but nothing was happening, and you either ran into whatever was in front of you or ran off the road. That generation of ABS could brake better than an average driver, but not a skilled on, in ideal situation, but was dangerous in situations where one wheel wasn't getting grip for some reason. Plus there was the problem that people didn't let the ABS do the job. They only pressed the pedal as hard as they would on a non-ABS car rather than jamming their foot down on the pedal and leaving it to the ABS to prevent wheels locking up.
But ABS has moved on. We now have separate ABS channels for each wheel. What's called EBD - electronic brake force distribution. When ANY wheel reaches the point where it would lock up the pressure it reduced on it and only it. That means you are getting close to ideal braking performance. An expert driver in a properly set up car - ie, with perfectly set brake balance - on an ideal surface can do that. But in any other circumstance the ABS does better than a driver.
Plus we now have brake assist that takes into account that drivers don't press the pedal hard enough in an emergency to let the ABS work.
ABS has moved on technologically from being better than the average driver some of the time to as good as the best driver all the time.
Anyone except possibly Micheal Schumacker is deluding themself if they think they can brake better than a car with ABS, EBD and brake assist.
Well, except in a few very unusual situations the ABS on cars that are designed to deal with them aren't programmed to cope with, like "marbles", which are round stones on dirt roads, where you stop best by letting the wheels lock up and build up a pile of marbles in front of them.
