The genius who designed disc brakes for bicycles, put the front one on the back of the fork, a really bad idea, because it tries to push the front wheel out of the dropouts, unless the QR is really tight. The front of the fork, would have pushed on the side of the dropout, which is much safer. As for the rear, well, the top of the chain stay would have been a better position for essentially the same reason. I think they adopted it from motorcycles, but motorcycles use a different method of attaching the wheels.
