I recently had a call from a first gen Mazda customer whose Brembo rotor he just purchased lasted about three laps before it parted from the car. He called a reputable Mazda prep shop and asked them about it and was told that they have a couple thousand dollars in replacements and that this is a factory defect. Apparently the threads are bad in some way. However, Brembo will do nothing about the defect, not even talk about it. This can only mean they have a lot of them out there and have something to hide, in my way of thinking.

If you have purchased Brembo rotors please inspect the internal stud threads to make sure they are well formed and complete. Exactly what the problem is is unclear but you will be able to tell by close inspection if there is some problem with the threads.

Has anybody else had problems of this sort with Brembo rotors? Have you heard of someone else in any class having the same experience?

This could be a serious safety issue besides the thousands of dolllars that this may cost retailers and racers.
