Never trust a system that seems to be working

Not in the US. US trucks are built using standard truck parts, including off-the-shelf air brakes that fail safe.

they didn't always fail safe.

I remember a house at the bottom of a steep mountain grade that got plowed into on a regular basis especially during that time.

EDIT: hmm... seems freezing might still be a way to cause failure?

Failure at the bottom of a steep hill is a different type of failure caused by brake fade due to the brake drum swelling with heat as the truck goes down the hill.

But I believe at some point air brakes had to be reversed by law.

In other words, the brakes would apply on loss of pressure, instead of via pressure.
