I have been happily using one variety or another of Hayes HFX brakes for years. I brought the bike (2007 Heckler) in for routine maintenance last week, picked it up today. They suggested switching to Shimano Deores. I'm not very enthused about mineral oil as brake fluid, especially when it gets cold. We discussed it and they suggested Aavid Juicy 7s.
Proceed with the brake war.
