Electronic parking brakes are straight out of idiocracy.

I do not miss the manual parking brake lever. I very rarely used it on my C6/older gen Corvettes. What used to drive me crazy was when one of the cars was in for service and brought to the service drive for me to pick up, the attendant would pull up on the handle as tight as he could get it. Even the the ones with an automatic. Found out it was an insurance requirement for the dealership. I'm betting it's a system wide mandate from GM. Called CYA against any roll offs/litigation.

I like 21st Century upgrades, like the electronic e-brake!

For the record, I HAVE used an energency brake in an emergency and it kept me from going over the edge in Topanga Canyon once when a hung caliper boiled my brake fluid. I have also tried the modern electric switch while moving and it DOES NOT stop the car. It chimes and then doesn't engage. Living in LA, that hill by the Pink Dot on Sunset required use of a handbrake in a manual transmission to keep from rolling back in stop and go traffic. With the electronic brake I'd have to '3 pedal' it which is significantly more difficult.
Just because everyone else is doing now it doesn't make it a good idea. Its like GM let some brilliant men make a 650 hp miracle then put some asian teenage girls in charge of the controls. Guess I should just be grateful it still comes with 3 pedals...but I'm sure in 10 years I'll be having this same conversation about that too.

From P.191 of the 2016 owner's manual: "If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is held up. If the switch is held up until the vehicle comes to a stop, the EPB will remain applied."

Thanks for the info, good to know. Its still not a good idea.

Awesome. When I'm careening off a cliff I'll give the manual a once over to see if I missed anything. What if the electrics are dead? Still work then? And lets be honest; did you know that already or did you go look just now? Did ANYONE know that before right now? If I said EPB to any car guy would they know what that acronym meant?

I've broken a park brake cable (pulled the ferrule off the end) by pressing the pedal too hard. They're not foolproof either.
As a last consideration, they're preferable over a foot brake because a foot parking brake can't be modulated - if you press it too far and lock up the brakes, your only option is to slide to an uncontrolled stop or reach down and monkey under the dash. With the electronic one you just let go, and the computer is smart enough to know that you've let go and it'll release the brake (unless you've come to a complete stop). So by that measure it's safer and better than the old foot kind for sure. The hand-brake still has its merits though I suppose.

No idea if its useful, but passing it along on the chance it is and you've not heard of it before.

So if I'm understanding pg 191 correctly, if the vehicle is in motion the EPB will not set. And, if it was applied while the vehicle was parked, it will automatically release when the vehicle is put in motion correct ?

Almost. If the vehicle is moving it will engage as long as you hold the switch up. If you let go of the switch it will not stay engaged if you are moving. If you get stopped it will stay engaged.

Surprised no one put this video in this thread yet.

I wonder if we can come up with a similar term for threads like this.
As it turns out, it is the only "primary" function of the PARKING brake. The name tends to spell out what its function is. It's a parking brake. Not an emergency brake. Cars haven't had emergency brakes in a very, very, very long time. Not since dual-circuit hydraulic power brake systems were invented.
See my statement above. That hasn't been the case for a long time. Long before electronic parking brakes were even thought of.
Why not?
You need to get over that because it's here to stay, and will be included in more and more vehicles from more and more manufacturers. It serves its purpose as intended and even provides easy hill-start functionality that would otherwise require manual intervention on the part of the driver.
Keeping a parked car from rolling away is only ONE of the three primary functions of the parking brake.
we used to call it an E brake when the E stood for 'emergency'. If there is some catastrophic hydraulic failure, that lever attached to a steel cable would allow the driver to manually operate the rear brakes and bring the car to a controlled stop.
The other thing it was good for was taking off on steep inclines with a manual transmission; one foot on the clutch, one on the gas and one hand on the parking brake to eliminate roll back. None of which we can do with the new idiot switch.
I just don't get the electronic parking brake. In fact, I hate them with a fire to burn a thousand suns. I hate them almost as much as I lothe and despise 'infotainment systems'. Seriously, stop fixing stuff that isn't broken GM and stop putting features that should be relegated to minivans in the Corvette.

If it was an option I would have selected a manual emergency brake. I don't use the emergency brake to prevent roll backs on an incline, but at some traffic lights where the light cycle can be long I used to engage the emergency brake on my C6 instead of standing on the brake the whole time. I have not done that in the C7 because to disengage the emergency brake you have to step on the brake pedal before the emergency brake will release, which to me is an inconvenient intermediate step to get the car moving.
