08 narrow body, was driving fine this afternoon, nice slow (in traffic) start at the lights and the clutch pedal didn't want to return to the top.

Thought it was a dead slave but it seems the clutch fork doesn't want to return to the slave. I managed to encourage it back to place and it's working again but seems like it's a little slow to engage.

Are there any known issues with throw-out bearings binding on the input shaft or with the pressure plate that could cause this issue?

Any quick fix solutions apart from going to see Doug n Dave?
