Ran into an interesting problem. The ebrakes stopped working. Took it to a shop and they couldn't find anything wrong but the started to work. But I also noticed that with the brake control set to max braking the tires wouldn't lock up. They work but the deacceleration is not quite what I would expect. Anyone having issues with the brakes?
I have no issues with mine. Tow vehicle is 2018 F-150 with OEM brake controller. when I tug on the brake controller you can clearly feel that the trailer pulls. Effort is medium at 5.
The fact that they did work but then reduced in effort, would lead me to say an electrical connection. True that is you did not ratchet them when building the trailer they would have reduced effectivity, but then they would not work normal and then quit.
If we assume the electrical solenoids are working then it can only be a matter of a low current bottle neck, like bad connection on your tow vehicles plug, or somewhere along the dc12V wire backwards. I took out the Smitty battery and charger after installing my own battery, but I suspect that that system could be at fault as well. If memory serves me correct, then there is a warning about testing the breakaway with the tow vehicle connected. I would investigate that. You can start by using a volt/amp meter and connect it to the tow vehicles brake dc12Volt wire and apply the brakes. If you see the voltage/current increase then your vehicle is ok. Then move backwards all the way to the solenoid on the wheel. Then go from there.
