Default Pulling the C7's Parking Brake Switch While Driving



Would it lock up your rear axles? Would it do nothing at all? Admit it, you've always wondered what would happen if you pulled the parking brake switch while driving.

What about in the snow? Maybe someone should try it. Reminds me of high school in empty parking lots.

Really not necessary to perform a test. Just read the Owners 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.

And then cry when the GM tech tells you that the item's you tore up are not covered under warranty!
LOL!

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?

I don't think GM would call it an EPB(emergency parking brake) if it could not be used in an emergency. I don't think a parked car that is already stopped is actually an emergency.

If it could only be applied when the car is motionless, then I would think it would be called PB(parking brake).

I think the acronym is electronic parking brake, not emergency. I've never thought about pulling it while I'm driving though.

I think one of us should try it and report how it did. You first.

It's a parking brake, not an emergency brake. Zymurgy posted the wording out of the Owner's Manual about it. I've pulled it once while on the interstate; it's like putting the brakes on but doesn't lock them up and when you let go of it they release. No big deal really.

Not sure why on earth it warrants an "Editor" article.

While the acronym might be true, you wouldn't activate while the car is in motion unless it's an emergency.

If it's not an emergency, you use the pedal on the floor to slow down the car, not the button on the console.

Just another in a long line of articles full of necessary information we all need to know. Also, today, we found out that replacing the tires (tires, mind you--not wheels) with other than OEM will result in your vette looking cool, one of 8 ways to make it stand out in a crowd.

It's really quite amusing that the "Editor" thinks the C7 has more than one rear axle.

The emergency brake works great. The brakes are applied to the point of skidding. It is not violent, I recommend everyone to try it in the event you have an emergency you'll know what to expect. The emergency brake uses the brake drum on the rear wheels and is separate of the normal brake system.

The C7 must be really special then. Every Corvette I've owned has had two rear axles. One on each side of the differential. Now my 56 has a single axle housing, but I guarantee you that it has two axles inside( and I can remove them individually).

It has two axle shafts inside one rear axle.

Does that mean Romex is one wire even though there's two inside ?

about the 3rd day of owning my c7 convertible i pulled it at about 15 mph coming into work as an accident. (my mbz had the top actuator in that area) - anyhow, wheels locked up just the same as 'pulling an ebrake' in an old school brake handle car....

based on my experience with GM's parking brakes in C5 and C6 I would guess that you probably wouldn't notice

Don't know if the C7 parking brake has the squeaky reminder when the shoe material wears down; some other car types don't. Routine inspection would be in order - meaning taking off the rotor/drum and checking that brake shoe.

If the shoe wears into the drum, it is a tough job removing the rear rotor/drum as I assume these parking brakes are automatically adjusting, so they'll continue to adjust and grind further into the drum.

I've been thru this job (the ex drove around forgetting to release the parking brake that was partially applied). I would never apply the parking brake while the car is moving, nor will a high-school kid ever get behind the wheel of my C4 or C7.
