[QUOTE="Fred W, post: 1248295, member: 3828"] Yeah, what Ross said. When you pull the clutch lever it strokes fluid from the point of first resistance all the way to the bar, so the volume of fluid you push out of the master, down the lines, to move the clutch slave cylinder is significant. On the brakes, the pads hover over the disks, and the slave cylinder(s) barely retract from full engagement. When you squeeze the lever or press the pedal you are mostly just increasing the pressure in the lines, not much fluid actually moves down them. My theory is that the motion and friction of the fluid moving back and forth through the rubber brake hoses is what makes the fluid dirty looking. Or it could be the increased distance that the master and slave cylinders need to travel in their seals that wear and contaminate the fluid. Either way, the fact that the clutch is always so much darker more or less proves that the color is not related to moisture content as the brake and clutch fluids will have been exposed to the same amount of moisture.
