well something is grinding.

start by checking the backing plates to make sure they are not contacting the rotors.

awesome...will definitely look into it...also my calipers seem to not retract even with the brake pedal depressed...is it because i need to wait for my pads to wear down?

I just replaced my rear rotors, calipers, and pads at both wheels and have a similar grinding/scrapping metal on metal sound coming from both rear wheels.

I haven't had a look yet but hopefully it's just the backing plates rubbing against the dust guard or something basic that can be easily adjusted/fixed.

I also noticed before I took the car off the jackstands that the rear wheels with the lug nuts tight were hesitant to turn. Something is dragging, what is the most likely suspect? Backing plate, parking brake, something else?

Anyone else have this problem after replacing their brakes?

Did you bed in the pads and break in the rotors correctly?

Nope, haven't got there yet. Dragging noise was too much to drive the car out of the driveway.

check the brake pistons and see if they move in and out freely.

Some rubbing/grinding is normal at first - full thickness pads and full thickness rotors will do that sometimes. If it is loud at all, you may have something outta whack. If the car stops fine, I would go bedding. But don't drive it until you're sure you've installed everything correctly.
