^^Totally normal!! Did you see this video of Albert Biermann talking about the new M5 brakes... it was on the front page a few days ago. The M5 brakes make the same noises. The noise comes from the different metal expansion rates. Alloy hub vs steel rotor and the oins used to connect the two different metals together.
