It doesn't take any speed to get this effect, just for a tire to slide while braking. Even just pulling into a parking spot slowly is enough force if one tire rolls over something like sand or gravel which offers less friction allowing that particular corner to lock and trigger the ABS. Since you state you were on gravel provides a classic example of a surface that ABS has a hard time interpreting.

So no worries, your ABS is acting normally.
