shit i have a problem with my front right brake. When I apply the brakes to slow down I hear like a faint hissing noise coming from the brakes.
I have the brembo cross / slotted rotors with AEM metal Master pads.
My friends tell me that the noise is coming from the metalic on the pads when they rubb on the disc.

I do re-call after having to brake hard one night on the highway. After that thats when the noise started to happen.

Is this common for aftermarket brakes?
