so, this just started happening yesterday

when coming to a stop as i'm parking or arriving at a stop sign.... just before coming to a complete stop, the ABS cycles. it only does it under light braking at at maybe 1-2 mph. it cycles once, that's it. it sounds like it's the passenger front side. the ABS motor doesn't even come on.

any ideas why this would happen? braking is normal otherwise. ABS light is not on and ABS operates normally during hard/emergency braking.
