This is ironic, because the spot-type disc brake is an American invention. In 1898, Elmer Ambrose Sperry of Cleveland designed an electric car having front-wheel disc brakes. He made a large disc integral with the hub on each wheel.

In 1967, Federal Motor Vehicle Safety Standard 105 set specific performance tests that led to the widespread introduction of disc brakes on American cars in the early seventies.
