Has the actual method of braking changed, or have they just substituted an electric motor for the hand lever or foot pedal to 'apply' the force to the cable operated parking brake?

The most important fact I needed is that it's a cable system, not a pressure brake that clamps down on the driveshaft or transmission. Maybe I should explain the situation that is driving my question. My son is learning to drive. A driving instructor that is teaching him has a car equipped with passenger side accelerator and brakes. Of course my car is not so equipped. But, he said I should take my son out to practice in-between lessons, and that I would be able to use the parking brake to stop the car if my son lost control...provided that the parking brake was a cable system. He said that if it were one of the other types (which Outbacks apparently had at some time in the past) that using the brake in that way would damage them.
I'm just trying to ensure that the system is a cable system rather than an "independent" braking system. At least I think that was the term he used.

I think at one time 'hill holder' used by Subaru with some manual transmissions may have been a driveshaft clamp, but that is not the case on the '02 Outback.
I understand what your instructor is attempting, but let me say that it is a crude substitute at best.. The problem is that a rear parking brake is not very effective on a moving vehicle. Weight transfer forward means that the front brakes do 90% of the stopping in a normal situation. Even locking up the rears with the parking brake will mean an extremely long stopping distance if the service brake is not applied. If the gas is applied, it would completely overwhelm the rears brakes alone. Worse yet, skidding rear tires can result in a loss of control, with the back end even coming around (oversteer). Lastly, this is very hard on an AWD system. The center differential can take quite a beating if only one half of the brake system (rears only) are applied hard. "Handbrake turns" can be done in snow or ice in an emergency, but again, it is very hard on the drivetrain.
Net: this is a last recourse type of maneuver, and not something you should do on a routine basis.

Thanks very much. That's the information I was looking for. We weren't going to do very much of the parking brake solution...maybe 4 or 5 trips around the parking lot of the school across the street. It's just something the instructor said would be good to do between his sessions with my son...just so he doesn't lose the feel of driving between lessons.
But I don't want to damage the car in any way and if doing this has even a chance of messing with the AWD, I'm not going to do it.
Maybe I should go rent a car.... :^)

To be honest I'm not sure.
I did the rear brakes on my 98 Forester (drums) and my dad's 02 Outback (disc), but I haven't worked on any of the e-brake models yet.
