Installed new rotors anf brake pads. scraping sound when turning left..?
 

I just installed brand new drilled rotors and pads on my 2010 Mazda 3 GT.
First off i had a HELL of a time getting the front OEM rotors off. Had to use WD40 and a propane torch as well as a small sledge. Nothing was keeping them on but corrosion. I finally got them off, put on the new ones and got everything back together. Took it for a ride to bed the breaks. Now after a bit ofdriving the breaks are good aand hard and no noise from rubbing, but when turning the car without even breaking there is a loud scraping sound. I am hoping it is just the dust plate, I havnt had a chance to look as its now dark. I read online that some say it could also be the bearing...I hope not...does anyone else have any ideas? I dont think beating the hell out of the OEM rotors to get them off would have done any damage would it? The suspension should havr absorbed most of it?

Let me know any ideas. Im checking tomorrow and ill upload pictures if i can.
Thanks.
