Many hydraulics only can be adjusted on one side. If the other side gets dirty you have to clean it very carefully or it sticks. I tossed my hydraulic brake set and put in Avid 7 which can be adjusted much more easily. Hydraulics are great if you get very expensive brakes or if you don't care if they squeal but I second fietsbob's recommendation for Avid 7. Sorry that doesn't answer you directly.
