+1 Wayne and a real good clean up of everything with an air line but wear a mask for protection so you don't breath any of it in.I know from my experience with race cars that carbon ceramic brakes can be quite noisy, especially when they being used gently.
You may want to try being a bit less gentle with the brakes or try applying some brake pad silicone compound (grease)sparingly to the back of the pads (between them and the pucks/pistons) which may damp out all or some of the resonance .
