Noisy brakes are almost 95% installation. Were the brakes thoroughly greased? Are the caliper slide pins greased or otherwise working properly? Etc.

Then bed-in and whether or not they were installed on used rotors, which sometimes the grooves on the new rotors and the surface on the fresh brake pads create harmonics.

...

I've used centric rotors several times with outstanding results. In many worlds, they are considered an outstanding OE-style rotor. It is very rare for rotors to warp under normal driving conditions. If they are off-set to the hub, if the wheel lugnuts are way over-torqued, or if the calipers are not evenly applying the brake pad....those things will all warp a rotor quickly....and yet the rotor will often get the blame as crap.

Just to be clear, I've used cheap chinese $25 rotors that don't warp when installed properly, with good hub centricity, working calipers, and torqued lug nuts. Centric is far from a cheap chinese rotor.At the very least, they are an appropriately priced chinese rotor
