Trailer Brake Control
Hello, I have a diesel F-250 2015 with an integrated Ford brake control.
My problem, when I use the brake pedal to brake my fifth wheel, very little current passes to activate my brakes even if the control is maximum (10).
When I manually activate my brakes, everything works normally.
Yesterday I asked a friend to log on to my fifth wheel with an F-150 2011 and it's the same result.
These tests were done on the spot by lifting a wheel from my fifth wheel.
For the owners of Ford, did you have the same problem?
I am told that the brakes will work according to demand when driving with the fifth wheel. For my part, I made the route Quebec-Florida and I do not feel the fifth wheel brake when I press the pedal but works very well in a manual way.
I'm waiting for your answers. Thank you
I was suggested to have an independent brake control installed, is that the solution?

I have an '05 F250 which, a short time ago, I had an issue with the integrated brake controller. Now, Im not sure on the '15's but the 05's the controller output is based on brake demand. The slower the vehicle is traveling the less voltage and braking power is sent to the trailer brakes. Even when set at max you may not feel the the trailer braking given its size and weight. You may want to test on a lighter trailer? An unloaded utility trailer you should be able to lock the wheels when braking with the gain set to max. You may also want to check the braking system on your 5ht wheel. I was having issues on my SnowPro snowmobile trailer in addition to my brake module (bad solder joint).

I have a '15 f250 with integrated brake controller. I have it set to MAX to pull my 30 foot Toy Hauler. Prior to buying this truck, I had a Prodigy brake controller on a Ram 2500 and the Prodigy provided a more aggressive braking action to the trailer. The Ford feels less aggressive but works great and stops the combination without issues. The fact that you can activate trailer brakes manually and everything works makes me think all is good. I have heard that many owners add a different, aftermarket, brake controller. If you want a more aggressive system, then that would be the way to go.

To follow up my problem, this morning I did a test with an other truck that had a manual break control and every thing works perfectly by just pressing his pedal break. So, now I'm sure that is my break control who is not working properly.

Do you have a dealer near by that sells / does maintenance on trailers? If you do they have a tester that can be plugged into your trailer plug to test everything out. It tests for voltage output with the brakes depressed.. Im not sure on the '15's but my '05 output is based on travel speed.

Hmmm,,, You are raising a question...
I thought the brakes are just proportional. Meaning, the more you brake with the tow vehicle, the more voltage and thus braking action goes to the item being towed.
The minus - and plus + permits more or less overall gain within a range.
The amount of voltage applied is proportional to the truck's brake so the harder the truck is braking, the more voltage is sent to the trailer brakes.
I'm not aware that truck speed has anything to do with it other than the driver's perception of how much braking needs to be applied. The truck should apply a linear voltage based upon its braking.
If you squeeze the actuator controls and you get brakes, then the truck's brake control is working.
Braking dynamics will be noticed depending upon the tow vehicle: item being towed (Its brakes), brake setting, driver/operator, environment (dry, wet, snow), etc.
That's why there is a - and + to accommodate variations.

Tekonsha 90195 P3 Electronic Brake Control
I was thinking to install this electronic brake control in my truck because the integrate break control in my truck is not working as much I would like. Is there any one change brake control in their truck and is it easy with the kit they sale all together? Is it easy as a plug in?

I wonder if Car Toys installs them? I had one installed on a Motorhome. The company I purchased it from had to run the wiring and tie it into the brake system for proportional braking.
There are many online.... Look it up on Amazon. They have kits..

You do realize the brake controller works in conjunction with speed/ skew, and yaw sensors. If I am towing my 24' cargo trailer empty at 30 mph I don't notice much brake control at the trailer. When loaded I can tell the difference when applying brakes. The hard I apply the more brake control is sent to trailer. The truck is controlling braking for both truck and trailer. It can feel a stronger braking action and adjust accordingly. If it didn't then you would be constantly smoking your trailer brakes. It sounds to me like it is working properly. Aftermarket units cannot use all the sensors the truck unit can and that's why you can feel more braking on the trailer. The harder the brakes are applied the more inertia the truck controller is sensing and the more braking power it will pass onto the trailer.
