I think we have the same Brake Buddy as you. We inquired at the Tampa RV Show last January about getting it serviced. We were informed it had to be sent back to the factory for service. I can't recall for sure, but I think it had to go to Oregon. Since we are also from Ontario and were moving around last winter, it was not practical to send it anywhere. It is holding together, but does make some noises on occasion and one of these days, we feel it will fail.
Maybe someone else can provide a service location. C.W. will not touch it.
