  • Interesting, I was unaware of that one.

    I’ll look more into it later, learn about its failure modes and whatnot, but off the top of my head, it seems like it would still be a less effective system. I think I would much rather have one axle working. That mitigates the case where the two wheels are on different frictional surfaces, which could leave you with just a single wheel braking.

    And still, if the fluid reservoir is a single undivided container, I’m not able to imagine a case where two wheels - horizontal or diagonal - would fail at once.



  • Diagonally opposite? No, it’s front and rear. However, brake fluid reservoirs haven’t been split for decades now, so if your fluid leaks out, every wheel is affected. It’s still highly unlikely that you’re going to have a leak that suddenly dumps all the fluid, unless you’re driving a very old and rotten car, in which case you probably know what you’ve gotten into.

    Brakes that “fail on” while the vehicle is moving can be catastrophic for some dingus in a car. Truck drivers have much more intensive training and specialized licensing.

    Hydraulic brakes in a car will still stop the car in a relatively controlled fashion even if the system is incredibly degraded, and they are purely mechanical. With wires, there’s a chance that the brakes go from “working normally” to “not working at all” without any warning. Hydraulic brakes fail gradually.
