After replacing/ machining my front Rotors to many times to mention . I broke down and bought a pair of slotted and drilled rotors. At the same time installed caramic pads. After a few months I'm started noticing a rough feeling and noise when I apply the brakes. Is this to be expected with this set up or should I be concerned ? As always you guys have been a big Help, and any thoughts or comments are greatly appreciated.

ROCK ON !
