Noise/sensation question: ABS or 4Matic?

Gretel - our 91 300 TE 4Matic - has us pondering over a new trick.

Rolling up to a slow stop, we sometimes get a slight feeling through the brake pedal that almost feels like ABS engaging - on a small scale. ABS engagement, if it's happening, shouldn't be surface related (one, this only happens at slow rolls - speeds like 2-3 mph. Two, it doesn't matter whether the road surface is clean & dry or sandy or wet.)

So - we're wondering if what we're feeling is the 4Matic kicking in.

Figure the next step (one for tomorrow morning when the sun is up and the 151 is flushed ) is to flip the 4Matic test lever to the off position and see if I can reproduce the feeling.

Any ideas anybody?
