They buy 100% genuine 'Brembo' parts off eBay for 99p . . . then slag Brembo off when they don't perform?
Jeez, I don't know.
I stopped trying to help them many years ago. When you finally get through to them that maybe, just maybe, you might possibly have bought a pile of 99p crap, they go off & buy another pile of 99p crap . . . . 'cos apparently, it's cheaper that way?
