I have no idea about manufacturing source. And, even for a bad vendor, 999,999 out of 1,000,000 may be good, but if you're driving the car with that millionth caliper, well - it could be a bad hair day.
With my employer, I know the tolerance for a failure leading to a fatality, is targeted for 1e-9 failure rate or less, that is - one in a billion or less.
I know that the hotrodding world tends to wing it a lot more than the corporate world, because the corporations are the ones with the big lawyers who file the big law suites, and who in turn get sued big-time. Even so, I don't like to roll the dice with my life.
