Why would an 06 mustang make a grinding noise in the rear and stop pulling

SOURCE: 06 Camry, new breaks/rotars now sounds like metal and grinding.

First, if the brakes are stopping the car OK. Check that the metal shields behind the rotors are not touching the rotors...that can make terrible noise though it's not serious and is easily corrected by bending. If that is not the problem, bring it back to whoever did the work immediately!!!
I'd much rather see a car not starting than one that can't stop...Obviously dangerous and important not to delay having looked at!

The rear calipers on that model rotate in, it requires a special tool.

If you pushed too hard directly in, there is a chance that you may have damaged the caliper.
