JuniorBirdMan Posted June 13, 2017 Share Posted June 13, 2017 I have been told that if you don’t have any trailer brakes you WILL KNOW IT. But not sure I will be able to sense reduced vs. full. In the "electric brakes" mode I can get them to lock up using the manual brake 'slider', although I get the dreaded "Trailer Disconnected" message. In "electric over hydraulic" mode I can't get them to lock up even at max brake setting (10.0). If you have an area where stopping distance is not a concern then you can try using the same approximate brake pedal pressure without the 7-pin connector installed (secure the cable to the tongue so it doesn't drag the ground) versus trying it connected as normal. Do it with the transmission's 'Tow/Haul' mode off so you don't confuse the tow mode's enhanced downshifting with actual braking action. After a few tries you'll have a good feel for when the brakes are working, if they are indeed working at all. I've got the 18.5 Elite so I'm guessing it'll be an even more pronounced difference with the heavier Elite II. I have an appointment with the Ford dealer on Monday to have the latest SSM (#45803, I think) applied. I'll post a followup after that.
