Just put new rotors (stock brembo) and pads on (Hawk). After installation and bedding (by installer) drove home and seemed fine, although i was taking it easy with the new brakes. Later that night out driving again, noticing a loud banging when braking heavy. The Heavier the braking, the louder it gets. bam bam bam Bam Bam BA MBAM BAM!!!! it is VERY unsettling when braking hard.... The frequency of the banging does seem to cycle with the rotation of the wheel.
My first thought was warped rotor, except there is no pulsing pedal and is not noticeable under 'normal' braking. I took it back to the installer and they immediately said 'Yep - rotor is warped - no brainer'. I was still skeptical given the conditions required for the banging - but I follow their lead anyway. I say damn and ordered another rotor. Installed yesterday - banging is still there!! exactly the same noise so does not appear to be rotor related.
I have scoured the forums - can't find anything quite the same. I am thinking maybe bad hub/bearing? Still strange though since there is no noise at all (turning, normal braking, etc.) unless braking heavy i.e. at a stop light or something. Any thoughts????
