Everyone, I decided to rebuild my brakes. They have SS lined calipers but when I took them apart I noticed that there was some cruddy stuff on the yellow anodized pistons. I cleaned it off but some of the anodizing came off. I ended up with the raw aluminum. Should I re-use these aluminum pistons with new o-rings or should I replace the pistons since the yellow-ish anodizing wore off in places that the brake fluid will make contact with the aluminum?
Thanks in advance for your help
