rakes stick when trailering. It only happens when at a slow speed, sitting at a traffic light, when the brake pedal is pressed to stop

Brakes sticking after a stop is likely not a direct issue with the Tekonsha Primus IQ Trailer Brake Controller # TK90160 you asked from. Once you have stopped this proportional controller will not have power still applied unless the inertia sensor has gone bad, but that would likely impact braking at other times as well.

It could be an issue with the actual brake assemblies needing to be adjusted or from a bleed-over of power from another function. I recommend cleaning your trailer connector on both the vehicle and trailer side using a little sand paper to see if some minor corrosion in the connection is the issue. Then you can add dielectric grease # 11755 to ensure there isn't a future issue.

If that doesn't solve it, then I'd adjust each brake assembly for correct turning function and after all of that if you still have an issue you may want to look at replacing the magnets in your assemblies.
