I got a 2008 gmc 2500hd I just installed new brakes/rotors and calipers and now I've got grinding noise from them what could I have done wrong I had did both rears

If you have a grinding noise then you need to get back in there and inspect everything. I just had to replace my fronts due to me trusting someone else doing "safety" inspections on my truck and they let my front pads wear all the way down to the plates. At least they were due anyway so no real problem.
