7 way trailer plug issue...
I have an '09 Ford F450, and I've got an 'ongoing' trailer brake issue. I've taken the truck to my local Ford dealer ($100.00+ to check) and said they could find no problem, but if it still doesn't ...

My 2010 F150 FORD Truck has the built-in OEM Brake controller. I'm not sure when this came out but was not on my 2004 F150 Truck. I'm thinking the 2009 F150 was the first year for this OEM Ford brake controller.
When I first got the truck and hooked up to my trailer I found out I did not have electric brake action except when I operated the slider bar.
It turns out the 2010 FORD OEM Brake controller is really embedded with the truck electronics and the speedometer has to be indicating at least 10MPH before the brake controller engages the electric brake action. Using the slider bar over-rides this action.
I am not a big fan of this but was confirmed by the FORD Folks to be true. I kinda like the idea of pushing in my brake pedal when stopped at stop sign and actually apply electric brake action on the trailer. The only way I can do this is reach down with my hand and operate the slide bar to hold the trailer brake action while being stopped at a stop sign.
My 2010 OEM FORD Brake Controller works just fine when going faster than 10MPH when applying brakes pushing down the brake pedal.. I could slide the trailer brakes like you indicated by setting the controller too high of setting when pushing down on the brake pedal.. Mine is set around a 5 setting for my trailer electric brake operation.
You may be running into something like this in your 2009 Ford truck.
