Technically that isn't true, but as a practical matter, it does not matter. ABS looks for a tire that is about to skid and releases the brake pressure so it does not skid.

It has nothing to do with the rate of slowing, the speed sensor either generates a long pulse width -- the tire is in danger of skidding -- or a short pusle width -- the tire is turning. The rate of change doesn't matter.

But none of this has anything to do with the problem that the OP has.
