We just got back from Myrtle Beach. I noticed a yaw when applying the drum brakes; a new but wholly unappreciated experience. When we got home I had a one of our boys listen to the wheels for magnet noise which confirmed two brakes were AWOL. Long story short; a lead wire to one magnet was broken off (the insulation just cracked with age and led to wire breaking) and the magnet on another assembly was a wedge and showing the windings. So this weekend I had the wife put on new disc brakes (she only started complaining when it got to be 10 PM and 45 degrees
). The system is Kodiak brakes, Dexter actuator, and a Prodigy controller running at about 6 to 7 volts at boost 1. We tested the brakes on Sunday and what a change. For the life of me, I cannot get the trailer to bump. I tried all of the tricks; deaccelerating into a turn with no brakes applied, a lower 5 volt setting on the prodigy and while turning into a stop. So I am now convinced that 2Air and Rich are right on. The Hensley does not bump the tow vehicle with proper braking force applied by the trailer.
BTW, our original break-away switch was also AWOL. I cannot see what is wrong with it, and it was working only a month ago. It looks like the way it works is that when the plug is pulled, the spring-activated contacts close and complete the 12 volt
circuit. Simple, and fool-proof, but it still malfunctioned after only 5 years. New Bargman installed, problem solved. With the crumbling insulation on the wire and the pristine-looking, but inoperative break-away switch, I now have a new perspective on the state of trailer safety on our nation's highways.
