Long story short, my electric brakes have never worked right. I've gone through the trailer and right now am fighting with my Ram dealer because I'm pretty positive the factory brake controller in my 2013 1500 is a piece of junk. One thing I came across I'm not sure of though. On the Dexter Axle website I found an instruction sheet for replacing brake magnets that shows a retaining clip holding the magnet on the arm. I don't have those on any of my brakes, should I? Seems unlikely they'd all be missing since new but stranger things have happened I guess. It's a 2015 X23B with 7" brakes.
This is the document I was looking at -
