I set the parking brake, which may or may not be an e-brake for all I know, only in 3 situations:
1. Parking on a slope.
2. Parking with 5th wheel attached.
3. Parking in a bad neighborhood. With the Ravelco now installed, makes it harder to drag away.

the 23 and up have the electronic parking brake modules so they are activated with a motor and some noise is probably normal when the mechanism clamps.

The F150 have this same setup and make this foreign noise if your not used to it. BTW the only time I use my parking brake is when I'm using the boat ramp so it get's somewhat frequent and never had a problem with the mechanical brake function.

I think it sounds like the alarm on the death star. I like it.

I always use mine because I often parking on slight inclines that otherwise cause the truck to come to rest against the parking pawl, the transmission makes a ruckus when I take take out of park the next time I move. this is more exacerbated when I have a trailer hooked up.

I have never tried applying an electric parking brake while in motion, but I have always wondered what would happen. Part of the question has also been whether it would immediately release or stay locked. I have never had the perfect combination of conditions to test it. (Low traction, open area, wife not with me . . . )
I suspect the systems are set up to prevent use while driving, for safety reasons. This makes them parking brakes, not emergency brakes.
The system Ford uses is an electric motor actuating the rear calipers. They do not default to any position if they fail, they merely do not change position. IOW, they don't fail applied or fail released, they just stay as they are.
I have never heard of any electric parking break applying with the vehicle in motion, so claiming to be worried about them applying at 70 is not likely to get you anywhere. But you're welcome to try it.

but yeah for it to happen there would have to be a few simultaneous failures that align to allow the parking brake to come on while driving at speed. Aka take your pick of something else that is more likely to fail to cause you danger than this
you have more reason to fear any idiots on their phones driving next to you than this
