I just got a set of used brembo calipers that had 80k miles. As with all the used brembos, it's got the usual chips and scratches. Was the OEM finish a paint or powder coat? I'm debating on whether to just install them or have them rebuilt and powder coated. If the stock finish is a powder coat and they seem to get pretty beat up from daily driving, I might not bother spending the $500 to rebuild /powder coat. But if it's just paint from the factory and powder coat will stay looking new for years, it would be worth the cash, especially to be able to match them to the car color.
