I asked Brembo how to identify if the discs are genuine. I was informed that Genuine Brembo Discs should...
- be either blanks, cross-drilled, or slotted. No combination of cross-drilled and slotted. The drilled or slotted discs are coated in a zinc/cadmium plating to help prevent rust and ensure disc longevity.
- have identification number starting with "09" or "08" such as 09.xxxx.xx. The Brembo discs also have a Brembo Logo and stamp on the disc lip.
- came in a thick brown cardboard box. The fakes came in a thin white cardboard box.
- be machined all surfaces including inside hat except on the ventilation vanes. Fake discs have rough cast hat, with a wide gap between the rotor vanes and the braking surface - not machined at all.
- weigh heavier than the fake discs. Brembo brake rotors are high carbon discs, and have the ability to better dampen vibration and noise
- have two equal and identical braking surfaces. Both sides have exactly the same thickness [10mm?]. Fakes Brembo discs have one side thicker than the other.
- have Ventilation Vanes extend out to the very outer edge of the braking surface (both inside and outside). Fake Vanes are sunken into the disc surface around 6mm (on the inside and outside), meaning there is less material connecting the two disc surfaces.
Fake Brembo Discs...
Both discs are fake!The Genuine "Brembo"stamping c/w logo are clean and more easily distinguishable...
... whereas the disc shown below with not-so-sharp "Brembo MAX" stamping and w/o logo is questionable. You judge it for yourself. Im doubtful and I will not buy this one...
