To kick the back end out, just push the clutch in, turn the wheel over, press the gas, then side step (or pop) the clutch. Simple.

Life is about managing risks, and the risk of having 100% power loss while moving is nearly nil. It doesn't take much power for the E-brake to actuate the hydraulics of the calipers and lock the tires.
Go spend some time with the CTS-V guys on the Cadillac forum and ask them if they hate their E-brake or if it's caused them a problem (hint: they don't, and it hasn't). It's the same system, and it works phenomenally well.
It actuates the hydraulics for all 4 calipers, bypassing the ABS valve, and it stops the car RIGHT! NOW! This is a bad thing, why? I'm guessing you're going to say something like, "100% brake hydraulics failure"? See my "managing risks" statement above.

The only difference between the electronic and handle versions is how the cable is pulled taunt to engage the parking brakes. One uses a handle and the other uses an electronic motor.
The electronic parking brake system has no connection to the hydraulic brakes, nor has any way to engage them.

I came here looking for information regarding dealing with steep inclines with the new e-brake and wasted 15 minutes reading through this completely ridiculous thread.
So, for anyone else stopping by looking for info and not pompous opinions and assorted misinformation, I'll sum it up....
Original poster's legitimate question:
Helpful answer:
From the Cadillac CTS-V 2011 manual page 9-37
Same goes for 2012 and 2013 models but found on different pages.
Automatic EPB Release
The EPB will automatically release
if the vehicle is running, placed into
gear, and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve park brake lining life.
The EPB can also be used to
prevent roll back for vehicles with
a manual transmission taking off on
a hill. In a situation where no roll
back is desired, an applied EPB will
allow both feet to be used for the
clutch and accelerator pedals in
preparation for starting the vehicle
moving in the intended direction.
In this situation, perform the normal
clutch and/or accelerator actions
required to begin moving the
vehicle. There is no need to push
the switch to release the EPB.
If you are towing a trailer and
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑53 for more information.
Thank you, c54u.

what the hell? seriously?
what happens without battery power? it is an EMERGENCY brake after all.
what happens if you want to use the handbrake for any number of things?
you may WANT to load the car up slightly against the handbrake (test clutch, etc.,). you may WANT to leverage the handbrake while working a car on or off a trailer.
a sports car should be able to do a handbrake turn.
bottom line, just like everything else, only more so (it is an emergency brake after all) it is vital that the e brake ALWAYS DO EXACTLY WHAT YOU TELL IT TO, ONLY WHAT YOU TELL IT TO, AND NEVER ANYTHING YOU DON'T TELL IT TO. It should not rely on battery power to activate or deactivate. it should not 'turn off' when the car begins to move.
surely this is not right?

This is 100% INCORRECT!!! I own a 2011 CTS-V with an electronic parking brake, and I have changed the brakes and examined the brake setup and I have a set of shop manuals. The CTS-V has has the exact same setup as the current generation C6. The rear brakes have two brake systems, a caliper and rotor for normal operation and a drum brake system (built into the rotor) that is actuated with a cable and used exclusively for the parking brake.
The only difference between the electronic and handle versions is how the cable is pulled taunt to engage the parking brakes. One uses a handle and the other uses an electronic motor.
The electronic parking brake system has no connection to the hydraulic brakes, nor has any way to engage them.

I guess I will start practicing the heel-and-toe method while I am out today. Maybe I shouldn't own a stick because I sometimes use the e-brake to prevent rolling back. It's just the way I have always done it.
I bet the C7 has hill assist programming just like the Camaro.

One thing for certain, with this type of PARKING BRAKE system, you do have to be careful after extreme intensive use of the brakes such as track use or autocrossing. You cannot set this type of parking brake until the brakes have cooled to a more normal level. If you are really using these brakes to their max performance level, it will probably take about 20 to 30 minutes for them to cool to the point that you can safely set the parking brake.

After reading this thread,all I can say is I'll be glad when we get the actual specs on the car and can start having meaningful conversations....and stop with the ridiculous nit picking.
This is not directed at the OP,he had a valid question. It was to the donnybrook that ensued....

With respect to possible problems with generic E Brake systems, there was an interesting scenario that happened during the recent NY Times test drive of the Tesla Model S.
When the driver set the E Brake after pulling to the side of the road with a dead battery, he set the E Brake.
By the time the flat bed tow truck arrived, the battery was indeed dead. They could not get the E Brake to release even after talking to Tesla headquarters and trying to plug in the tow truck's jump start battery.
Eventually, they had to drag the Tesla onto the flat bed with the wheels immobilized and unable to rotate.
As more and more cars come equipped with these E Brakes, we all may have to develop new habit patterns when confronted with electrical problems such as dead batteries and alternator failures etc.

Obviously those of you questioning the use of the parking brake to start moving on a hill haven't driven on Madison street in downtown Seattle with someone right behind you. Without the p-brake not rolling back is impossible on that street or actually most east west streets near downtown here.
