There are two normal causes. The clutch is worn out or there is a leak in the hydraulic clutch slave or master cylinder. To check the clutch, press the clutch slave cylinder down. If the clutch slave cylinder bellows compresses down to the slave cylinder, the clutch is worn out. Check the clutch master cylinder fluid level. if this is low, then the clutch cylinder need to be checked. To check for a hydraulic leak in the clutch slave cylinder, remove the cylinder's bellows and check for any fluid. If fluid is present, rebuild or replace the cylinder and bleed the system. To check the clutch master cylinder, check the back the of clutch master cylinder for leaks. If fluid is present, replace or rebuild clutch master cylinder and bleed the system. In my experience, hydraulic leaks occur at the clutch slave cylinder.
