Northern salt sprayed roads would assist that corrosion. Stainless could have been used, but if they were using an aluminum housing maybe that was nixed. .02  |
Actually, they're Geomet coated fasteners. You can see the coating has dissolved, which is the shiny streaks running down the face of the calipers. That's classic acid exposure. The Trophy calipers on my C6 Corvette are several years old and still look like new.
If the goal is to get these brakes looking great again, check out the work of Mike Golding at
http://thepowdercoater.com. He does some amazing powdercoating and is an expert at caliper rebuilding. He's famous on the Corvette forums.
StopTech probably won't just send new bolts because, to replace them on an ST-60 Trophy caliper requires removal of the cross-over tube. With corrosion, there may be a risk of stripping and things could go downhill fast with a DIY replacement. This is all within the abilities of Mike Golding, however. So he may be the best way to move forward and get this resolved.
Good luck!
