[QUOTE="FJReady, post: 1248298, member: 465"] Here's my theory on why the clutch fluids gets darker quicker than the front brake fluid: The clutch gets used way more often. The seal around the actuating cylinder isn't perfect. Everytime you squeeze the levers (clutch or brake) a molecule or two(OK, I'm not really sure of the rate) of air gets by the seal. And especially, as Fred points out, that the travel of the clutch is greater than the brake, there is more opportunity for air to get by the clutch master cylinder piston than the front brake one. I would estimate that given the clutch gets exercised with every upshift/downshift that the actuator shaft sees way more travel than the brake. My $.02. Worth what you paid for it.. [/QUOTE]
