Well, we have mandatory, in depth checks every year for trucks and afaik, downhill mountain streets have “breaking ramps” with sand etc. Then again, I’m living in the northern European flats, so I might have no clue but I think accidents because of failing downhill braking are very rare.
But when regular brakes fail you can’t stop. When semi truck air brakes fail it forces the truck to stop.
