32gtr Clutch / Slave Cylinder Issues

[r32line]

So if someone can help diagnose my cars current issue I would be grateful.

Last few weeks driving car I noticed the clutch biting point seemed to be quite low compared to normal. With clutch in and in 1st if I started to come up a bit off the clutch it would almost engage straight away.

Driving on the weekend I was at the lights, in 1st, clutch all the way in waiting for green. I noticed revs start to drop and then felt the car starting to move forward. Tried to pull it out of first but couldn't and by then needed to grab the brake to stop car moving. Then I realised the clutch wasn't coming back up. Managed to yank shifter into neutral, put on hazards and turned off car. Started it 5 mins later as lights went green, put it in 1st and was moving and could engage each gear after that no issue.

Got to my destination 5 mins later and checked under the hood and realised the clutch fluid was below minimum (although I cannot see any leaks under car even now after days in garage... though there isn't much fluid really to leak out from what I can see).

I had a friend pumping clutch you could see fluid go down and then bubble up. I filled it up with Dot 4 but the above situation didn't change. If I go through gears it is all good but if I am stopped, in 1st with clutch down it as if the clutch starts to lift even though pedal isn't moving.

So with all the above in mind I think the problem is most likely (in order);
1 - The clutch slave cylinder
2 - A leak issue in the lines that is stopping the clutch from maintaining constant pressure.

If someone has experience with the same symptoms as above and can confirm I would really appreciate it.

Cheers

Got standard clutch hoses? They're probably leaking (I had that issue, except more severe).

[r32line]

Yeah they are all standard I think. Maybe it is a hose or a seal?

Broken M/C

Look inside car for fluid leaking down inside of bulkhead.

Clutch worn out.

As there's no fluid on the garage floor it points to a master cylinder problem.

They don't usually leak inside the car as the booster separates at the firewall.

Probably leaking passed the internal seals.

Then it will operate as normal some of the time but slowly leak when held under load.

On a GTR with a clutch booster, any leak from the master will pass into the booster and end up being burnt. Won't ever see that it's gone until it's gone.

So I got the car up on a hoist and I can see fluid leaking from the hose going into the slave cylinder and that same hose has a leak at the other end. So clearly that flex hose needs to be replaced. Can anyone suggest my best option to find one?

- Try a Nissan dealer?

- Mechanic suggested taking hose off and just make up a hose to match

- Aftermarket, but not sure where I can find this specific hose

Any help appreciated

You mean opening up a browser tab, typing in ebay.com.au and searching for a clutch hose to suit your model hasn't been done yet?

[r32line]

Thanks for your help dick head. I did try ebay but could not find the hose the goes into the slave for sale separately.

You remind me why I got away from using forums...

This is why it makes me wonder why I bother.

You can lead a whore to culture, but you can't make her think.

Hahaha brilliant. I bought a braided line from UAS, but there are lots of options, including Nismo replacement lines. It would have literally taken you less effort to search for it than to reply here complaining that people aren't spoon feeding you everything. Listen to your mechanic and get it made up in braided form.

I know SFA about your problem but I found that at times asking questions on forums can be tricky, I could not understand why people do not just answer the question if they" know " the answer, instead of saying go to Google or do a search on SAU

It only takes about the same time to answer and be unhelpful

I found that some of the answers on SAU were too old to be of any real help, as most things have changed over the years, but someone always pops up and points you in the right direction .

Also my search skills are nothing to talk about and I am sure some people are much better at it than I am

Let's use this thread as an example. The post before OP blows up, he lists his issue (split clutch line) and some possible fixes. He types "Any help appreciated". GTSboy replies with a quite plain but sarcastic reply, but it does "help" OP because he didn't say he checked ebay.

So if someone replies with a *hint*, no matter how dumb it seems, do you take the positive or the negative from that?

BTW, when my clutch line split, I didn't start a new thread and then bitched about people telling me to look up stuff myself. I researched and bought a correct item (still going strong 3 years later).

How hard is that to do? Pretty hard these days it seems.

What has split is NOT the clutch line... The things others have found on ebay is a clutch line which comes down from the master cylinder but that is NOT what needs replacing. What I need is the short hose shown in this picture;

Help is appreciated yes, but telling me to go to ebay and buy a part that is NOT the issue is not what I define as 'help'

The braided teflon lines from eBay (well, from just about ANYWHERE, including eBay) totally replace the hard line as well as the shitty little flex. And the descriptions of those items for sale usually explain that rather well.

Also has the benefit of getting rid of that silly pulsation damper loop in the hard line. And guess what.......this has all been posted about on this very forum so often that you couldn't help but find it if you actually did search.

What shits me the most is when people say "I searched and couldn't find anything" when what they really mean is "I searched. Once. Using inappropriate terms. Oh, and possibly the wrong search engine. Then I gave up, rather than trying some other search terms or a bit deeper looking around and went off for a lovin' spoonful."

What you are describing and what you posted a picture of most certainly is the clutch line.

I did just search for an answer like the above using various search criteria and I assure you I could not find this answer... but I am sure this is because I am an idiot.

What shits me is people who spend longer posting about how people could search things etc etc... Some people come onto this forum and might ask the difference between an r32 and an r33 and most people would just rip into them for having the audacity to ask such a question rather than just answer their question or actually link them to an answer.

Regardless of the above, thank you for your help. Can I ask you then to clarify further (because I am an idiot and haven't replaced a clutch line in an r32 gtr before) the braided clutch lines you are talking about replaces the line down from the master, the hard line and the flex hose. So I could just empty the system, rip all those out and put the braided line straight in, fill it up and be done?
