Any idea what's going on with my brake levers? These are not scratches or scrapes -- they are some sort of curlicue lines in the aluminum of the levers. They remind me of worm damage to wooden ships at sea. These are the original brake levers that came with my bike. Thay are 2009 Shimano Ultegra and they're mounted on a 2009 Trek Madone 4.7. The deterioration began a number of years ago and had been getting gradually worse.
