2005 Squealing Brakes

Can anyone tell me about the brake recall for 2005 C6's? My new 05 squeals like a pig when I apply the breaks. Pretty darn embarrassing for a car that cost $50K. I've taken it back to service dept and they declare everything normal. The amount of brake dust would totally amaze you. I have to rinse off wheels after taking afternoon spin to grocery store. Any ideas?

Here's the bulletin. Only for Z51 performance package. I had mine replaced a while ago - no noise, less dust.

Some customers may comment that when they apply the brakes, the vehicle exhibits a squeal noise. This squeal noise is heard coming from the front or rear of the vehicle. Vehicles produced with the Z51 sport package are equipped with larger rotors and harder pads.

Recommendation/Instructions:
Replace both the front and rear brake pads with the part numbers listed below. Both front and rear pads need to be replaced due to the difference in composition of the brake lining material. The existing rotors should be used and it is not necessary to machine the rotors.
