Loosing Clutch Fluid, From Somewhere...

[SiR_RB]

On Sunday I took the car out and found it extremely hard to put it in 1st, literally had to use 2 hands to get it in, lucky I could get it home safely

Today I took it to work and it left me at a set of lights with no clutch pedal ! Noticed fluid was below the L line, so I topped it up and got it to work,

Now I just got home and it started playing up again, checked fluid and it's on Low again

It's not leaking inside the engine bay, and it's not leaking where the clutch pedal is either

Slave is a nismo unit looks dry and not to be leaking ?

Anyone have any ideas what it could be or what to check ? When I topped it up the clutch pedal/shift was perfect

Could it leaking past the master cylinder and into the booster ?

[GTSBoy]

Yes well.....given that it's a GTR and therefore has a clutch booster, it won't leak back into the cabin until it has filled the booster and wrecked the seal on the firewall side of it. So that will be where the fluid is. Rip it off, take it to be kitted. Pronto.

Running standard lines?

[SiR_RB]

Thanks guys

Standard lines, including the rubber hose coming off the slave

Just ordered a new braided hose and new master cylinder

[niZmO_Man]

The rubber clutch hose on my car split and caused the pedal to die, although a lot quicker than yours. Maybe check that out if you want.

I replaced it with a braided hose, bypassing the standard block thing underneath the driver's floor. Not sure what it that did.

Il have a look

The braided hose I got only replaces the rubber line and keeps the rest of the factory lines

Happened to me couple of months ago, new slave kit and was good as new

Probably the better option. I wonder if the standard hard lines help with pressing the clutch pedal.

Issue was the stock rubber line coming off the slave

Put a nismo one today, bled it, all good !

Yay I win

Lol

Old perished rubber served itself well for over 20years

In r32 gts-t (not sure if Gtr are the same) they have a clutch cooling loop. Same principle as power steering cooling loop in front of your air con condenser. It's pretty rubbish and makes it difficult to bleed. I ditched mine in favour of a braided line straight from master to slave.

Yep, same on my GT-R (did the same thing).

It's actually not a cooling loop so much as a pulsation dampener. Hence the rectangular box in the middle of it. Supposed to make the pedal feel "better".

[iruvyouskyrine]

That's odd. I felt better when mine was in the bin.

[GTSBoy]

Commonly the case. They don't seem to help with uprated clutches, and how many Skylines are still running around on a stocker?

[niZmO_Man]

I did find that it was slightly "nicer" to press the clutch with the standard crap in. But I have a very heavy clutch. Matter of time before the clutch bracket snaps...

Figured it was more of a damper design than a cooling loop. Oh well, weight saving .

Where did all your oil go?
