Clutch Slave Cylinder (Maybe) R32 Gtr

[ls128]

Went for a charity car cruise yesterday..car had been very rarely not wanting to go into gear (i.e i'd have the clutch all the way in and it wouldn't select)

Didn't think much of it as it would just be a little grind when trying to shift quickly, when I Went slower it went in.

Went to do a 3 point turn in a car park, put clutch down to the floor....no pressure.

Pushed the car into a parking spot, saw clutch fluid all over the ground.

Spoken to a few of my mechanic mates they all think it's the slave cylinder that has failed, does anyone have any idea? Or seen this before?

Car has a HKS Twin Plate clutch.

Thanks!

Was your reservoir empty? If its the slave you"ll see fluid leaking. Fill the reservoir and watch it while someone pushes on the pedal (and look elsewhere on the line for leaks) Get a torch and look under the clutch pedal for interior leaks from the M/C and then under the bonnet.

[ls128]

Yes, when I checked it at the time, it was empty.

Ok thanks, I will give that a try - in the mean time should I shop around for a slave cylinder?

There was fluid all over the ground in the initial spot, and again when I moved the car when the tow truck came.

Yes, buy a slave. Also buy a master, as it will also be old and ready to die. Also, buy a braided hose if you're not feeling too poor. You will appreciate the feel.

Did a master and slave just recently. RB25 stuff. Not very expensive from Nissan. About $90-$100 on the slave and $140 I think on the master.

Go to Nissan. Keep the feeling

[ls128]

"Keep the feeling"?

It's a twin plate..its the heaviest clutch I have ever felt!

Just jap has slave for 115, master is 300..braided clutch hose is about 150.

Kudos motorsports have the slave for $99, master for $205 and take your old rubber clutch hose to a brake/hydralic shop and they will make you a new braided one for less that $80.

+11ty. This is excellent advice.

[ls128]

It's definitely the slave, had a proper look under the car tonight. For the extra 15 dollars I will probably go to JustJap as it is very very very local for me, Not sure if I will do the master, as that makes it a much bigger job then just slave, correct?

[GTSBoy]

No, it makes it about a 15 minute longer job. You stil have to bleed it anyway. And when the old master fails in 3 weeks from you having to bleed it with the new slave, you'll have to bleed it again anyway. Save yourself the pain, and do it all the first time.

I wasn't referring to clutch feeling. Read between the lines (Toyota genuine parts - keep the feeling)

Heh yeah, I realised that about an hour after I replied and was re-reading the post.

Got a genuine nissan slave for $105. Swapping it out tomorrow morning and bleeding. lets hope!

So, Swapped Slave cylinder, Master cylinder - now when the car is in gear, and the clutch all the way down to the ground, car will creep forward like the clutch isn't engaged.. looks like i'm up for a new clutch

Disagree - what you have still sounds like its not fully disengaged. My guess is there's still air in hydraulic system. I'm told it can be a bitch to bleed the clutch hydraulics, especially the "dampener box", or whatever its called.

Good reason to get rid of it. Hence my advice for the braided clutch hose.

Ok abit more info:

Saturday, put a new master cylinder on. Adjusted the master cylinder inside the cabin (almost all the way, only 1-2mm of thread left) Worked for about 20 minutes of driving, then started doing the same issue. Often won't go into first, or reverse. Start the car in first, with the clutch fully in and the car will crawl forward like it is in gear (despite the clutch being foot to the floor.

System was gravity bled and pump bled for an hour. in total we bled it 3-4 times.

Spoke to a mechanic friend and he says that he had a similar issue and when he pulled his clutch out several of the clutch springs had come loose.

Suggest you grab someone who knows how to adjust the push rod on the master cylinder.

No way is it right if you're down to the last threads ????????

Have you any free travel at all?

Without free travel the master cylinder will never prime correctly.

Did anyone check the booster unit.

[ls128]

We adjusted it more because before adjusting the rod it still wasn't giving enough pressure - my mechanic had a look and he said there was enough free travel.

Check booster unit as in how? We didn't touch the adjustment rod inside the booster unit.

Where did you bleed it from? If its just from the slave, then that I dont think it will be effective. Actually, i cant really see the point of a bleeder on the slave....

Yeah from the slave..after we dropped all the fluid out and put the new master cylinder on. We spent a fair bit of time making sure all the air was out of the system..
