Just to clarify, when towing with the "ford factory brake control'.

If the ABS becomes active, as it would have in BobW's experience on a slippery roadway.
There is NO TRAILER BRAKING at all, not even if you have time to reach down and manually apply the trailer brakes.

So, if a Ford pickup is towing and the ABS becomes "active" the trailer will push the truck to make the experience seem a lot worse.
