Do we know for sure that the Emergency Brake is applied to stop the vehicle when it is in motion and the switch is activated? With all the electronic gizmo's, I wouldn't be surprised if there was some sort of override that utilizes the actual brakes when good ole Dale decides to flick the switch.
Just a thought. Anyone got any solid info on that?

Well I'm not sure there was a definitive answer from the video. It appeared to me that this driver got a wide variation in braking between his tests, wide enough that it raises more questions. At higher speeds the car stopped somewhat gradually (perhaps the initial speed overwhelmed the system or it faded?), while at the lower speeds it appeared the braking was much more aggressive. How about in wet conditions? I still don't know what to expect should it happen. And this turns on the brake lights, too? Is that confirmed?

manual hand brakes dont Lock up UNless you Bang it ALL the way up in one throw .... im sure what the electronic c7s parking brake does is what I would do by pulling gradually upwards on hand brake... the electronics just does it for you...
with that said as much as Im against technology taking over certain things I wont miss the handbrake-- the c5s never really worked and the c6 is really in akward position especially with a passenger...
the G8 is hidden away and blends in When not engaged but in the way when engaged....

Thanks, Bill! I'm aware the EPB is utilized, but was curious as to whether the EPB was used in it's entirety when the switch is activated while the vehicle is in motion.
Obviously this would be the case if there was a brake failure, but if not, I was curious if there was any particular electronic override that would utilize the actual brakes if they were indeed still functioning properly.

Everyone should practice this AND how to shut down the engine. Technology is great until in a panic situation you don't do what you should be do what you mind tells you. You do recall the Toyota cars going out of control with the floor mat issue and folks holding down the start button to no avail? Learn and practice how to kill the engine in an emergency.
Also as we've chatted before make sure anyone riding in your car knows about the emergency door releases.

I just wish the parking brake button/lever itself had a light on it so as to show you when it is engaged like other cars. I know there is one on the dash but looking down at the toggle and seeing it illuminated would be helpful. I've already driven off a couple of times with it engaged ( manual trans obviously). Does the car automatically turn the brake off if you forget and if not how much damage is possible?

Good info. The parking brake is just brake shoes in small drums that are part of the rear rotors. Pretty small so don’t expect they would stop like applying the disk brakes aggressively!
Funny, Granddaughter wanted to learn to drive a standard shift a few years ago when she was ~18. They were visiting from OH so let her learn to use the clutch in my 2014. She started at the end of the driveway toward a gate to the back yard. Thought she could do no harm- BUT held my hand on the parking brake lever- just in case! Didn’t have to use it, after three tries she got it moving forward! She’ll be getting a Masters in Charleston SC when she graduates college in OH! Hope she doesn’t expect to borrow the Grand Sport!

If you are going forward it automatically disengages. In fact, that's one way to handle hills when you don't trust the "hill hold" feature. In my experience the "hill hold" prefers a pretty steep hill to activate and is very iffy when the hill is slight, but still enough to roll back. Of course, you can do the traditional two-step and use neither, but the fact is that feature of the EB is there if you want to use it.

I was using it to do a 180 as it was pouring rain on the autocross course this weekend and there was a hairpin turn. It lags obviously but it does let off when you release it. Very difficult to use while turning the wheel. I gave up after 1 try.

Not sure why this is even a question. All "parking" brakes are can be used as an emergency brake.
