Need help with the following issue on my 2016 F250 6.2 CCSB. Intermittently when I tow a trailer I will have a front caliper stick when braking. I’m calling it a sticking caliper but it could be something in the proportion of braking power from the truck to the caliper. I’m not entirely sure what the issue is at this point. It doesn’t do it every time, it will start and stop within the same trip. I have taken trips for many miles when it never showed. It is completely random in appearance. When it happens It really pulls hard when I apply the brakes. It has done this in both directions, left and right. At times it is so bad that I have to purposely steer in the opposite direction in order to stay in the correct lane. It has done this with a TT that has electric brakes and a boat trailer that has surge brakes. It has been to Ford and of course they cannot find an issue and keep blaming the trailer. I explained to them that it happens on different trailers with different types of braking systems, they don’t listen because they can’t test anything unless it is actually happening at that moment. I know this question will be asked, No it never braked like this without a trailer. I am at a total lose, we are scheduled to take a 4,000 mile trip shortly and I don’t want this issue to be a problem. Anybody have something like this happen? Any ideas where to look?

 

 

Truck only has 12,000 miles so everything is new. It did this on our very first tow. I am leaning towards some issue with the built in trailer sway control applying the brakes. No difference with both trailers, the symptoms are exactly the same.

 

Turn your traction control off, all of it. You have to hold the button in for a couple seconds until you get the message on the dash. These trucks have body roll control and there is a possibility that your system is registering the extra trailer mass as a body roll condition. There's times when I am towing in hilly areas where I have to turn mine off.
