I have owned and used a Classic Brake Buddy for over 16 years now and have never had any problems. Unless you're pulling your toad with a diesel pusher motorhome, it seems to me (and I can say this from experience) that you will know when the Brake Buddy is engaged as you will feel the "drag" on your motorhome as your toad tries to stop the motorhome. (My Brake Buddy is so old there is no remote warning light in the motorhome indicating when the BB is engaged.) I have had a couple of times that the emergency cable was pulled out by turning too tightly when cornering which engaged the BB and I could immediately tell that the BB had engaged. I also place a board between the Brake Buddy and the seat to provide a better contact area for the BB on the seat. All in all, my Brake Buddy works well for me!
