Hey fellas, my clutch has recently developed an unusual problem. It's kinda hard to explain but here goes. When I push it in and out it grabs then lets go . If I push it in and try to let it out smoothly it comes out a little at a time. its really annoying to drive especially with heaps of stopping and starting. Ive checked the clutch fluid its fine and there are no leaks. Any ideas what it could be?. Cheers.

Its either the slave cylinder full of crud (being down low a common thing)
Or the master cylinder grabbing
First thing i would do, clean everything up (spray up with degreaser) wait till it all dries
Then check for leaks,if no leaks,id pull the slave cylinder apart and clean out (Fairly easy)
Or the master cylinder is shagged (about $60 ish new,save the hassles and buy a newie)

I would not bother with cleaning the slave, as replacement units are not too expensive. ( I think it was around $50)

I tried putting a kit in mine - was given the wrong size rubbers.

The rubber boot on the slave cylinder isnt split at all ???

Its a hydraulic over hydraulic system
Its either the hydraulic system the cylinders or pistons or rubbers ect
Or the clutch itself is karput
But if its driveable here and there not likely the clutch itself

Money is still on the slave and master cylinder

*edit
Also check your clutch line ,give it a thorough look
It could be leaking ,sucking air here and there causing this

I have read in this forum of people having issues with the pivot lever (also known as the withdrawal lever) which operates the clutch snapping off on one side of the "Y"

When this happens the clutch can stick and not release properly.

Other things which can cause the clutch to jam up is the springs falling out of the clutch plate. I have had this happen on a few vehicles over the years.

what Ric has mentioned happened to me, however this just made the clutch never disengage fully (so sitting at lights with clutch pedal in and it would keep pulling forward a tiny bit), other than that it went fine for me. no release problems.

Could be the thrust race is sticking on the shaft.

Yep that's what I was talking about. It sticks because of uneven pressure when the pivot lever is broken on one side from what I have read.
I'll see if I can find the threads on the subject.
