The clutch went during the winter on our farm truck, a 2003 L200 Strada. After changing it we bled the system and it all seemed ok for a while. Then the clutch pedal started not returning after pressing down. It was not sticking as such, just not returning. It could be pulled back up with just one finger, no resistance! We have tried re bleeding it a couple of times, but no improvement. Is there a return spring anywhere? or is there still air in the system? Apart from when bleeding the oil level is not going down so there is lo leak in the system. Any ideas anyone?
