Break-away Cable?

It won't be like a parachute, like someone said, more like a drogue chute - trailer brakes slow the combo, while the vehicles steers and maintains control.

If you've ever pulled a vehicle with a tow strap, you'll understand - you want to keep it taught or you're going to get yanked around and sacrifice control.

CONGRATS MIKE .... your the one that IMO is starting to get the idea. I've often said the last thing I would want to do is to take one hand off the wheel to muck around with the manual TT brake control and jockey it to get the amount of braking you THINK might be right all of which assumes that your unbilical cord wasn't ripped out during the hitch failure and now have a trailer w/o brakes bent on rear ending you. I want BOTH HANDS ON THE WHEEL with my FULL ATTENTION to simply maintaining control of the vehicle bringing it to a stop as safely as possible. My biggest concern is to as I alluded to in another post in this thread is to keep my wits about me and stay off my TV brakes and simply forget about the trailer since it's going to do what it wants anyway and worry about what I have some hope of controlling and that is my TV and the safety of those there. The one saving grace is I run this scenario thru my mind several times a day when towing as a reminder and have often practiced just how quickly simply letting off the TV gas and applying full trailer brakes at say an initial speed of 50 t0 60mph the whole rig slows down below 20mph at which time things have slowed down to something that just might be manageable.

That is a matter of opinion. Some like it shorter than the chains so that if the chains catch the trailer, it sets the trailer brakes. Some like it longer than the chains so they can manually control the trailer brakes with the brake controller unless they lose the trailer completely. Then the brakes activate.

While it might just be an opinion among non expert arm chair engineers the SIX credible and what I would consider authortative (some more than others) sources that Ron cited in the link I provided above all say the breakaway switch should be activated when the safety chains are still connected. I have never seen a credible or authorative source other than personal opinions to suggest otherwise.

It's obvious one has the choice.

OP here...
That does it. I've made my decision. I've heard the arguments for shorter and those for longer. I'm leaving our break-away cable alone and just the way it came from the factory.

and...I've decided to just not allow my trailer to break away at all so it doesn't matter what length it is.

Thanks to all who weighed in on this never to be solved debate. You all make good points to be considered.

Now, next question. Who makes the best truck?

I wouldnt want the trailer brakes to be activated fully unless the trailer was completely detached and rolling around by itself

if my tt came unhitched, the a frame would be supported by the safety chains, the umbilical cord would still be attached, so the tt still has lights and controlled braking.

if the safety chains failed(or total hitch failure), the trailer becomes a completely uncontrolled vehicle. of course the umbiblical cord would get a massive yank, the plug would likely come off the whip and the breakaway cable would get pulled applying full braking on the tt.

my safety chains and breakaway are setup that way. safety chains will cradle the front of the a frame so that it wont dig in and the breakaway wont do anything unless there is complete separation

Is there an authoritative statement concerning the length of the breakaway cable?

I may be missing something, but it seems as long as the umbilical cord stays attached to the TV, then full braking controlled by the brake controller is still applicable, right?
