Vibration is the cause. You may be be lucky with brake grease, there are a few choices,or you could fit Teflon shims.
So, the solution is to take brake pads out, clean everything, put brake grease on, and put everything back in place. ??
What kind of noise is it? Is it more than just the extra noise from a disc with vent holes?
I drive with slotted discs in my Saab and the braking noise is quite noticeable.
My Brembo brakes get very noisy under more then average braking.
What could be the cause of that, everything looks ok.
Any Brembo Abarth drivers have/had this issue. ??
