Thanks, Pete
I have a leaking system. At present I don't know where the leak is located.
After 2 months driving in the spring, I put the car back in the barn for 2 months. When I came back yesterday, the mastercylinder was almost empty.
Filled up the clutch worked again, all though softer than normally. To me this indicates a leak and not broken master- or slave cylinder.
