hi there, i have g35 03 6mt brembo brakes, every time when i hit any kind of hole loud noise comes from the bottom of the car. i have checked the car at the local dealer and they couldnt find anything wrong. I have brembo calipers but i think just regular non brembo pads installed by previous owner. Can anyone tell me could the pads make that loud noise. by the way when i am breaking seems that noise is less louder. Please Help Me

thanks
