So you're going downhill. You want to go slower. You either downshift or hit the coaches brakes. This causes the towed surge brakes to engage proportional to the inertial force of the towed vehicle's "push" against the coach. When the towed vehicle's brakes engage it slows down and there is no longer an inertial push against the coach. No inertial push against the coach equals no surge braking action.
If adjusted properly how do the towed vehicles brakes overheat unless the coaches brakes also overheat? You have to be constantly decelerating for the surge brakes to be constantly applied.
What am I missing?
