Caliper rebuild kit
 

I have a 2008 HHR SS. I am trying to rebuild the front calipers. I had them powder coated red and had to strip them to get them painted.
I have ordered the caliper kit and twice it has been too big. The parts they try to sell me are for 2.375" caliper pistons. My HHR pistons are 2 1/8".
Apparently the parts data base for this car all show the wrong piston size.

Has anyone had a problem getting the correct caliper rebuild kit? Can anyone give me a correct part number if you have purchased these.
Any help would be greatly appreciated.

Information on which callipers you have, as well as the current source/part numbers you have ordered would help.

More info, I do not have Brembos, I have the normal SS caliper. The part number for the Dorman Caliper rebuild kit that was too big is D351776

SS caliper pistons are smaller in diameter then LS or LT models, you may need to go to a GM dealer to get the correct parts, not the generic stuff

BTW; metric!

Thanks for the tip. I just went to the dealer and gave them my vin# and they also showed me the wrong ones that were too large. I will keep on searching!!

AllData says p/n 22705328

Thanks for checking, but when I check that part number is says that it fits all HHR's
so I suspect the database doesn't recognize that the SS has smaller pistons.

Is there a part number on the calipers that you can cross reference with ?

I'll check my 2008 SS calipers for any identification
