Without using the E-brake, you're relying on this to hold a 4500lb.+ vehicle in place.
A 1/4" pawl stuck into a notch on a 4" diameter 1/8" thick wheel.
A wheel that small doesn't provide a whole lot of mechanical leverage against that weight of the vehicle.
Has that system ever been known to fail?
Ahhh...YEA! Big time. Many times. Even on the smallest of grades.
I've learned about that not ftom Google, but from actual observation & experience.
I've heard that distintive ratchet sound of a failed pawl more than once. Don't even have to see the vehicle rolling to recognize that sound & just what the hell is going on when that is happening.

I've seen the results.
This vehicle. Dad's. (He bought it new at 18. His first new car.)
1976. 20 minutes outa the paint booth. Sitting in front of the booth doors & here comes a truck, making 'THAT' sound.
Nobody in the truck.
Rolled a 1/4 block down the slightest grade of a hill (3%? Maybe.) at just better than a fast walking speed, jumped the curbed & plowed directly into the passenger 1/4 panel & door.
Thats the closest I've ever seen the ole man come to tears.
The Insurance Co. wanted to write it off! It took over a year to get that settled.
All because some _____ was too damn lazy to set their E-brake.
