Ok, so I just switched out my old rotors for some slotted/cross drilled rotors from r1concepts, along with ceramic pads in the front, and I think semi-metallic in the back (from parts source). Since I've put them on, Ive been getting an odd grinding sound in the front end..... not really like the traditional grinding that Ive had with previous brakes either.... It feels fine for braking, and it only makes the noise at slower speeds (under say, 15km/h), and at higher speed braking it has a hum like noise, almost seems like a bass note vibration with it. Any ideas of what this could be? Thanks for any help!
