GC, I know only what I read but it makes sense to me. The point is that the spring rate is such that gravity on slopes up to some pitch (unstated) and normal slowing down without the use of brakes does not compress the spring and activate the trailer brake; whereas the (greater) g developed by applying the car brakes does compress the spring and activate the trailer brakes. Have you read the full article Jim referred to?

I think the problem with the overrun damper and overheating is that with a defective damper, the brakes do not release properly, unless you accelerate suddenly and powerfully after braking. If you slowly bring the entire train up to speed, the brakes may stay on, and overheat. I had exactly that with my Cobra, and now I have a new overrun damper lying around, until I get around to installing it..

Soar & drive safely,
