I have used my MaxBrake on my '06 with many trouble free miles. No IThink I have a problem the trailer brakes don't work, kinda' suddenly. I've got to be back on the road to Texas next week, and I don't want to change controller on the way. When these things fail is it overnight or do they get worse and worse? Any body got any suggestions? I hate to give it up, but I don't want to be broke down. Thanks for your help.
