They fail when cracks are not noticed, ignored, or otherwise, and people continue to drive despite the car slowing down due to the distorting/dragging drum. It's similar to continuing to drive with an overheating engine which just slows down until it seizes.
Education and maintenance make drum failure very unlikely.
