Brakes pulsating!?!

sorry I should have clarified I hace a 2000 S which doesn't have PASM.

I'd like to see if there is a comprehensive analysis of the Porsche ABS system.

And tips for preventing its need. I was always told that with ABS you wanted to pump the brakes which is completely the opposite of what I have trained myslef to do. For instance in autocross I'm often "quick hard and quick off" the brakes before making a fast turn. It was a trick to do this without locking up the brakes with my old Miata. With ABS its going to be another challenge.

Whoa, stop right there (no pun intended)!

You DO NOT want to pump the brakes on an ABS-equipped car. The ABS does the "pumping" for you. And about your technique of locking up the brakes...that is also a no-no. When you lock up the brakes, you are sliding. And if you are sliding you do not have control. Try locking up the brakes and then turning (actually, don't try it). You won't be able to turn. That's why ABS was invented. I would suggest finding an empty parking lot and doing some full stomps on the brake pedal to get used to the ABS activating.

Don't pump the ABS. That is the cardinal rule. Stomp on them hard and keep the pedal down. The ABS does the rest.

that's right pump the brakes for non-abs. Got it backwards.
Locking up the brakes isn't really a technique, more like an unexpected situation that is fairly common when really braking hard. Usually when you brake too late and stay on the brakes too long.
I had an instructor at a very challenging two day AutoX driving school braking so hard I thought he was going to put his foot through the floor board. yet he never locked up. A very violent feeling experience as a passenger.
