Squeaky Wheels/Brakes

I have a continual squeak & squeal when applying my brakes and also there is a similar noise when the car is coasting. New brakes have been installed and the pads have been changed twice since that time. Any suggestions???

did you change the rotors

Had a complete brake job, rotors, pads, etc.

Do you live in a place that uses salt and it could be rusty rotors?

No, I live in Alabama
