Nearly everything made these days there will be copies or counterfeit parts produced even with the copied brand name, the Chinese are very good at this as well many other Asian/3rd world countries, as for Brembo brakes not all their brakes systems are top of the range brakes, most manufactures (bike manufactures included) will contract out to parts manufactures for the cheapest price and that is where quality over quaintly goes astray, but don't mean you get crap just some parts are made cheaper for what mass produced items are contracted for, most bike manufactures and car manufactures want the best price to keep cost down so not the top of the range parts are used.
Modern times everything is outsourced and not everything is made inhouse, every bike manufactures do it same as cars, trucks etc. etc. and they been doing it for a very long time.
