i can adjust the controller however I thought i knew how. I have adjusted the gain and sync to max. Are there typically any other controls for a reese brake controller?

Thanks again for your help and input on this as my head is hitting the wall again and again.

these are the instructions i followed.

If you have both set at MAX and still have poor braking you have a problem somewhere.

Jack up one side of the trailer and while spinning a wheel have someone hit the manual control. That should SLAM the wheel to a stop. If you do not get this reaction from each wheel its time to start some deeper investigation.

Check and be sure that the controller is properly wired. The wire color codes can be confusing, and it is common to mix up +12, brake switch, and ground.

Check and be sure that the controller is properly grounded.

Check and be sure that the +12v connection to the controller is clean and tight. Check the voltage between the +12V and ground connections at the controller with brakes applied manually. If less than 11.5 volts, you have a problem in the power/ground wiring to the brake controller.
