I'd want to hear the rationale upon which that is based before simply guffawing heartily in the face of whoever is trying to sell the idea.

Why not do it ??? That little resistance from the E-Brake is to get the phony Brake Lock differential to operate....Try it and see if it works !
I say "phony" because with the money and engineering MOPAR spent on that system, they could have installed a Posi-Traction that actually works...
Just my opinion.... "BH"
Not at all the same thing. I would definately not do this with disc brakes, on drum brakes the cable operates the same pads as the brake pedal so I'd be less worried about damaging them. Disc brake parking brake system (in my experience) will not put up with this type of abuse for long.
It confirmed my suspicions so I'm a bit more well informed.....now what happens when you add Wrangler's Trac-Loc to the scenario?
That TF video shows you on film what happens and they mention it a little less than halfway through the video. They specifically mention Trac Lok and show you the rear wheels and what happens. Granted the video as a whole is painful to watch, it does cover this as far as it can be covered without being even more boring.
The emergency brake can be used in a very few scenarios, but it does work with Trac Loc. Old school or not it works with an open differential and Trac Loc.

The E brake trick does actually work when in a situation where one drive wheel has little or no traction and just spins. when you load it just a little with the E brake it will stop the spin and transfer some torque to the wheel with traction. this just might get you moving then release the brake and go on your way this is old school but then so am I,I used it more than once back in the fifty's to get the old Ford moving in the snow .
yes it will work and no it will not harm anyhting--infact that is what the Brake lock system does--but not with the E-brake it uses the pads on all four wheels (if you have disk brakes --shoes if you have drum brakes on the rear). It is another tool for your tool box if you are tight situation and nothing else is work. It has to work as long as your brakes will hold the wheel with the least traction --keep it from spinning before the wheel with traction turns---once the jeep starts moving then release the brake since it is holding back on both wheels.
