Kind of but if the electricity goes out it doesn’t matter how many circuits you have. They all don’t work. You could say the same about the brake fluid but I can’t flip a switch in the cab to drain the brake fluid but I can leave a light on to drain the battery. That’s why I’m curious what the fail safes are. They could have multiple power sources. We don’t know…
I was simply responding to your comment that there weren’t any fail safes to losing a brake line and there are. Losing a single line or two lines in the same circuit doesn’t cause a catastrophic failure and you can stop the vehicle albeit with reduced braking performance.
Easiest way to design it would probably be by making it a NC circuit so they brake unless they have power to open the brake cylinders.
