Trailer Brake Question

Okay guys I have a 2007 F-350 with the factory brake controler and I tow a 30 ft travel trailer and I'm having trouble with the trailer brakes.

I have jacked up the trailer and spun each wheel while engaging the trailer brake control and the brakes engage and stop the wheel. Now here is the part that is messing with me. When I take off down the road the brakes will not engage and I get a trailer fault in the message center of the truck.

I assume when you get a trailer fault in the truck it has to be something electrical correct?? If the brake pads were bad or the magnets were bad it wouldn't give me a trailer fault would it??

Any advice would be great this one has me stumped!!!!

Try cleaning the plug on the truck on the pins and on the inside. Mine does this about every 3 months and I have to clean her up. Just did it two days ago actually because it was doing the same thing. Good luck:thumbup:

This could be from resistance in your electrical plug but we have also seen many cases where there is a short in the wiring for the breaks or a bad brake controller. Also when you have the trailer off the ground make sure the brakes are really engaging. Just because the brakes will stop the wheel if it's spinning doesn't always mean the brakes are operating properly. While the brakes are engaged someone will need to really push on wheel to make sure the brakes are fully engaged. If the wheel still spins with only a little resistance it's likely that you have a bad magnet but a bad magnet still won't cause an error message on the brake controller
