Was following the procedure for doing the clutch system inspection and adjustment:
Push the release lever to retract the push rod of the the operating cylinder and check if the fluid level in the clutch reservoir tank rises or not. It rose. All OK.

Pressed the clutch pedal, and it went straight to the floor. No more actuating of the clutch. Clutch pedal goes to the floor and stays there.

Does anyone have any thoughts or have you been here before?

Thanks for any help.
