You will love the Hy/Rds, but be very careful to install them exactly as the directions indicate. Be sure the caliper arm fully opens under no lever pull, otherwise the hydraulics in the caliper will not be able to auto adjust for pad wear. DO NOT take up slack with a bit of tension on the lever arm. I am convinced that if Shimano had invented the cable-hydraulic caliper first then we would all be using it instead of full hydros!
