Clutch Bleed .... how?

Do any of you folks know the correct proceedure for bleeding the hydraulic system on the C2 clutch. (step by step approach! especially the cautions, as well as the do's and don'ts) Adrian Streather manual indicates that a pressure bleeder is required to carry out this proceedure effectively.
Any advice greatly appreciated.
 
1. Jack up rear and put on axle stands for safety and remove left wheel.
2. Put a 7 mm ring spanner (I strongly suggest a six sided version) on the bleed nipple and a long piece of tubing with the end in a jar.
3. Attach your pressure bleeder (remembering to clamp the vent hose on the reservoir).
4. Open the bleed nipple with the spanner and bleed off about 200 ml of fluid until it is clean.
5. Close the bleed nipple and remove the pressure bleeder and top up the reservoir with the same amount of (fresh) fluid you removed.

Getting your arm up to the slave to put/work the spanner involves a lot of swearing!
 
Hey thanks Steve. Very much appreciated. I had done a search before posting this thread and noticed you had replied to a number of clutch related questions, so was aware that it was something that you had done! The slave and master cylinders were replaced 20k miles ago, so i'm hoping the bleed screw is not too seized!! [&:]
 
Paul can I ask why you are wanting to do this. I had my system bleed by Chris at C of G, he spoke to a friend that said to do the job correctly, you must remove the slave cylinder to remove all of the dirty fluid and any possible debris.
This was not an easy job and to be honest the feel was no different. So I am curious why you are wanting to bleed your clutch?

Hi Keith.
As with most things it's a process of elimination. Took car out for a spin at the weekend, initially having difficulty engaging 1st and 2nd gears (not all the time). The gears were at no time forced, if they didn't engage first time, i released the clutch and tried again. Bizzar as i was on my way to a regional club meet at our local OPC! The problem appeared to improve once the car was up to temperature and the gears gone through a number of times. Having read a number of threads/posts on the subject, many indications point to the clutch hydraulics and bleeding the system, hence my question.
 
My c4 did the same just before the clutch needed replacing. Difficulty engaging first and second until warm (sometimes, and to the amusement of anyone watching, leading to me engaging reverse instead of 1st). 3500 miles later the clutch started slipping under hard acceleration (4500 revs plus) leading to a nice new clutch, engine tinware etc with the associated large hole in my wallet.

Not a very helpful/cheering post from me I know (Different drive trains etc). I hope it's is just a case of bleeding the hydraulics for you.
 
My problem was mostly down to having problems engaging first gear when the car was cold or very hot. Here bleeding the clutch worked for me. Here's what came out!

I also recently improved the downshift of gears under hard deceleration by fitting new engine mounts.
 
The joy's of 964 ownership i guess. Funny that Chris, because initially i found engaging reverse helped find first gear. Clutch was replaced 30k miles ago and the slave and master cylinders 10k later. Anyway i'll try the bleed first and see what happens.
Doesn't look to clean that fluid Steve [;)]

Thanks for posting
 
You may find that if you remove the floor bord the peddle will go down a little more, this helps with the bleading! regards Berny.
 
Hi Paul, the problem may have arisen because you don't drive the bl***y thing often enough!! If you need a pressure bleeder, I have one that's never been used. See you soon
 
Hey Brian. That's what i said to Harv on the way to the OPC. [&:] That's great Brian, hang onto it, i'll buy that from you. Cheers
