i am guessing you are talking about the brake proportioning valve. i just cut the arm off it and relocated it. easier. i hear if you just t it off your rear brakes are more likely to lock up in rain and snow. doesnt snow here but does rain out of the blue...
i got rid of mine, I put around 2000 miles on it only though, in rain, snow, and sun. So I cant prove reliabilty, or safety but I have not had any problems stopping yet. -Brad
