Clutch pedal a little 'sticky'

Had a similar problem when we bled the clutch recently - the pedal wouldn't get back to its original position as it couldn't overcome the spring. After some driving and additional "enthusiastic" pushing of the pedal it works properly back again.
(master and slave cylinders were replaced with the clutch 20k miles ago).

When I had my lux I finished up replacing the gear box due to the same problem and crashing the gears stripping some Syncro.
When the blue cotton bound hose was removed the rubber inside had started breaking down and a fairly large piece had lodged close to the the clutch end Check the fluid level and also check the contents of the hose for rubber debris.
Failing that solution then yes its going to be either the master or slave replacement route.
Just to mention tho when the gearbox was replaced and the fluid drained and replaced the clutch pedal was perfect. Without replacing either the Master or slave cylinders.
I hope yours is a simple fix

No! Join the AA and you get 25% discount, followed by 10% every year after, as a Club member. Just one of the huge number of discounts that most of us never spot. [8|]
Will,
Thanks. How you strip the synchros on your box? The Audi box used in the 944 uses cone synchros; not quite sure that I understand this.
When you talk of the blue braided hose, I presume you mean the one that links the master and slave cylinders? How do I check it for having bits of rubber stuck in it? Pull it off and have a look in I guess. Ho hum.
Interesting that cleaning the hose on yours (presumably when the gearbox was replaced) the clutch was fine. That's encouraging - thanks.
Where's the clutch reservoir? I guess somewhere near the master cylinder ... must go and have a look for it. I've never played around with the clutch hydraulics at all so it's all new to me - never even checked the fluid levels. When we changed the clutch itself we just unbolted the slave cylinder - we never broke the circuit.

I've got a year's free membership with the RAC ... voucher for it lying around somewhere ... I'm sure ... just need to find it in the tip which passes as a spare room/library here. (Would help if my long-staying-friend-in-the-other-spare-room wasn't using the third room/library as a general dumping ground ... grrr!)

The stripping was the diagnosis from the gearbox guys who replaced it so only passing on their comment.[8|] the reservoir is on the bulkhead near the chasis number stamp on the left as you look at the car small white with a black top

Hi Oli
I've circled the clutch fluid reservoir in the photo below. I needed to investigate mine last week when I thought it was the source of the fluid coming into the cabin, but as we now know, that's the heater matrix. [

Let me know how you get on, as I think I could do with changing this fluid on mine as it's a little black for my liking.
Cheers
James

Just a thought, have you jacked the car using the jacking doughnut near the front arch? This can bend the floor slightly.
Mine did this and the clutch pedal felt as through it was not going to return. The fix was to hammer the floor around the gas pedal.
a forum search my pick up this common issue.
hope it helps.

Chaps,
Thanks for the answers.
Darren - good one. As it is, no I haven't, and such a jacking mistake usually affects the throttle more than the clutch (been there, done that, had the odd looks from the neighbours while beating the living sh1t out of the car floor with a hammer - three days after I bought it in my case!)
Wil - I've had a look at the arrangement, and your comments about the blue braided pipe make much more sense now. Thanks.
James - thanks. As always, very helpful. I checked it, and found that the fluid level was low (on the 'min' mark, but the car wasn't parked on the level.) Topped up with some brake fluid and a bit of experimental pedal-pumping suggests that things may well have improved. I'll see how things go when I next drive it (tomorrow). Fingers slightly crossed, this may have solved the problem. I'll keep the thread updated.
Oli.

And - flip me! - they really were cowboys! (Very good-looking, I may add. But cowboys none the less!) []
... and on a serious note ... I don't think that the clutch change had any bearing on it at all. The slave cylinder was removed and re-attached without being removed from the pipe, and the circuit wasn't broken at any time. I think that there is possibly a slight leak on the pipe from the master to the slave cylinder - it looks a little damp; maybe that did arise from moving the pipe around at clutch change time, but I'm not sure. (Having said that I've done around 2500 miles on the new clutch, so if it is a problem from doing the work then it is very slow in making itself known.)
I do know that I haven't even checked the level of clutch fluid in the nearly four years I have owned the car, so I am suspecting slight weepage over that time. This is assuming that it has been solved by topping it up, of course ....

Chaps,
OK, drove it this morning and the clutch is fine. It was the fluid level - thanks James.
Always nice when what could be a big job turns out to be hardly a job at all.
(Downside was that I drove it to the bodyshop to have the mangled rear bumper replaced, so I won't be driving it again for a couple of days - alas! Even worse, I now have a Mk5 Golf Diesel as a courtesy car ... and it is sincerely nasty!)
