Brembo brake noise.

I have a general question for everyone. I just replaced my brakes with Brembo pads and rotors on my 08 g37 base. Since I've had them done they squeal quite loudly in the morning and sometimes I can hear them slightly when I come to a stop throughout the day driving. I've tried to contact Brembo about this but couldn't get anywhere.

Is this normal for Brembo or would this be defective?
