I have a 07 cobalt Ss 2.0 looking for left rear caliper bracket with free moving pins mine are locked up dealer wants 90 for new

 

Try somewhere like autozone or rock auto. Now if you must have an ac delco one, get the part number from the dealership and order it from gmpartsdirect.com. It will take awhile to get to you but it will be way cheaper than the dealer.

 

Autozone and advance don't carry it

 

OP, I bought a couple of rear calipers back in the day, I believe my passenger's side went bad and I still have a good driver's side or vice versa not sure a 100% lol. I'll double check my garage as soon as I get home and I will hit you up
