That's correct, there is a high possibility that even with the hitch dragging along the highway still being secured by the safety chains attached to the TT the e-brake may not activate, even if the hitch broke away clean....you could still have a run-away TT.
Another scenario; assuming that the hitch (TV receiver) and safety chains remained attached to the TV but the TT still broke away from the TV (ball shank sheared, ball mount cracked in half, etc.), ideally one wouldn't want the e-brake cable longer than the safety chains. The e-brake should activate just prior to the safety chains being pulled to their full length.
IMO it's difficult finding an e-brake cable attachment location on the TV that would cover all possible catastrophic component failure conditions.
My E-brake cable is attached to the same location as one of my safety chains on the TV's receiver (not ideal), but my E-brake cable length is shorter than my safety chains. I mocked up an E-brake location on my TV frame once, but then the cable was longer than the safety chains (unless I relocated and changed the angle of the E-brake switch).
Then there's the TT's 7-pin pig tail, how does it's length play into the equation (maintaining TT braking control within the TV under certain failure conditions)?.........that's for another thread.
