I'm not sure about other models, but the C900 and the 9000 both have separate compartments for the brake and clutch fluid within the shared reservoir. The result is that you can drain down the brakes (e.g. from a caliper) without in any way affecting clutch operation. Similarly, you can drain down the clutch without affecting the brakes. -- Grunff
