The calipers are made of cast iron. They do not appear to have any serious protection against corrosion and will probably rust within a couple of years like most calipers.If I were to paint it, for protection rather than appearance, I would do it black to keep them hidden. Now, if they're fixed caliper (i.e. brembo or alike), neon or bright colors would be awesome.
@pro10is: Are the calipers made of ferrous (e.g. steel or cast iron) material? So our calipers don't have any protection (i.e. plated or anodized)?
No problems, but it's best to partially remove them for painting. Simply remove the spring and then pull off the caliper body and remove the brake pads. This only takes a couple of minutes for anyone who is familiar with doing a typical brake pad replacement. Once the calipers are partially removed (no need to disconnect the hydraulic line) you have much easier access for painting. Hang the calipers using something like a wire, do not stress the attached hydraulic line. Keep the pads and rotors free from paint. Follow the directions that came with the caliper paint for more details. They give you a can of brake cleaner which is ideal to prep the calipers.Any problems or lessons learned while taking the calipers off to paint them?
That's the exact same kit I referenced above, just in yellow. It's the best kit available that I know of. It's less expensive at Tire Rack.
Insight is much appreciated. I was already thinking about some Subaru decals on them so thanks for that link!
