Quick and easy way to tell if your brakes are more or less working is to pick a driveway etc that has a reasonable incline and try backing up with the trailer wires disconnected from the vehicle so the reverse lockout is out of the picture

If the brakes are working it should try to tear the hitch off the vehicle with near zero movement of the trailer

Mine turned out to be no fluid in the master cylinder when delivered from the factory. Someone forgot to bleed the brakes I guess

After bleeding the brakes the trailer was dead stopped going up our slightly inclined drive way

If the trailer moves but with significant resistance it could be air in the lines or other mechanically related problems ie master cylinder failure
