With all the braking developments over the years whether its V, disk or maggy no offense but is pouring coke over the rim a a viable replacement for just setting your brake up a little better?
Going back to water vs oil, i'm another that has ran water in an 04 lever and it hasn't let me down once, a quick re-bleed once in a while and it's fine, adding antifreeze seems to free up the pistons a little bit if you're having issues.
