Have been running my MaxBrake for years and recently someone ran a red light and it has not behaved properly since. It sometime works and other times it wont engage the brakes, I am so bummed! Just replaced it with a Tekonsha Prodigy P3 and I hate it. I really do not understand how people tow with these things, it's TERRIBLE. Sigh... I think the unit is salvageable if there was someplace that knew a little about it and did electronic repair... Unfortunately the repair shop that replaced it cut the brake electric wire to remove it and pissed me off. Would not have had insurance replace it if I had know that. I cannot express how much I am bummed. Anyone got any thoughts on a place to hopefully repair?
