2004 Suzuki Aerio Repetitive Scraping Noise

I have a '04 Suzuki Aerio and had the pads replaced and rotors turned. After this when I drive the car for around 2 miles the right front side starts to make a loud repetitive scraping noise when the car is decelerating without the brakes being applied. This sound goes away when i accelerate again. This is a very irritating sound and dont know if it is a concern for safety. Does anyone have any suggestions about what it could be.
Thanks
