when I press the brakes going at any speed, there's a loud scraping sound from the rear right of the car. It also makes the sound when making right turns. any ideas?

 

okay, it seems there's metal on metal. a friend told me the caliper might not be retracting correctly. however, I just got all 4 calipers replaced, and rotors resurfaced from the local dealer. the work was done 1 year and 3 months ago. will this be covered under warranty? I paid almost $1500 for the full overhaul, which was a ripoff to begin with!

 

I would pull the brakes on that side and inspect the pads. They could have metal built up on them causing it to sound like metal to metal.
