I just had the brake assemblies on my 2007 Montana replaced with Dexter self adjusting assemblies due to a recent brake near failure. The brake controller on my 2011 F250 is turning off power to the trailer brakes at around 10MPH which leaves me with the antilock system to stop the truck & trailer. I can stop the trailer with the manual switches but not the brake pedal. Any ideas if this is programmable or just broke? The controller is the factory system.

 

Broke is my take on your problem, but either way it has to be a dealer issue in terms of repair or replacement. How can you tell it is turning itself off?

I believe that it (factory controller) is working as manufactured. Ford believes that at 10MPH or below that you don't need the RV brakes. You can check with the Ford mechanics but most of them don't even know how the system works. I would email the experts at FoMoCo before I'd believe a local Ford dealer. Maybe ask them to get factory involvement.

 

I interpreted this to mean when the truck got rolling over 10 miles an hour the controller went on holiday and split the scene.

.........OOPS!

 

Maybe you are interpreting it correctly. I don't know. That was just my take.

Really doesn't matter..... going up or coming down - it don't work below 15MPH.
