a good american video
It can perhaps be classified as "American". It's not good; it's a muddle, with a lot of fluff.
There's virtually no science there and some important bits of the narration are incorrect, such as the descriptions of friction and rotor size. There is information (useful facts) there, but in no way at all does it help anyone decide what brakes they need, because that's obscured by the rubbish; it's badly done marketing spiel.
