Fixing Damaged Caliper Help

Getting some serious brake noise. Replaced rotors, pads, still noise. Need to check my dust shields for being bent - but this weekend I had the pads off and I noticed on 2 of the calipers, several of the pistons were damaged. On the face of the piston that touches the brake pad, there are "chunks" missing. I have no idea if this would cause noise, but I'm assuming it should be fixed. I understand I can just replace the pistons and seals without replacing the entire caliper assembly. Can anyone explain how that is done? Thanks.

You can search google or you tube on how to rebuild calipers and replace the pistons. It might just be cheaper to buy rebuilt calipers though.

Yea I see that now. Looks like the caliper assemblies are like $30 (after core) from rockauto. But the pistons are only $9. Hmmm....

I've been down that road before and for the few extra bucks it's worth just replacing the caliper. You could try some high temp silicone on the piston faces as that can help.
