My CSC rear disk, (Cobra upgrade) brakes have sqeaked from day 1. The vendor has added some sort of spring to seperate the pads and they have looked at them one other time just say "dont be afraid to get on them at high speed to set them in". After 10k miles they still squeak. I ran into another CSC rider who complainded of the same situation with similar results.
Any other ideas or common problem????
