isuzu npr 200 clutch pedal clicking and not operating

do you have any pedal pressure?

Have got half pedal.but it is clicking on the clutch pedal and not disengaging cluth.

The click may just be a worn clutch pedal pivot bush worn out, check that there are no leaks at the master and slave, you should have a better pedal, you may have air in the system, half a pedal wont work the clutch normally, check the hydraulics first.

Thanks very much. I'll check it out. Cheers.
