After heating up, the brakes on my 2011 Regal turbo squeal loudly when they are applied. The noise is constant and actually has gotten to the point where it's embarrassing. My wife refuses to drive the car because of the noise. The pads are still at full thickness, and I've had the vehicle in for service a few times at the dealership I bought it from. Service mechanics keep telling me they can't replicate the sound. Anyone else having this problem?
