Gravity bleed 370Z with CSC every 6 months when changing the oil and replace with Dot 5. Remove the bleeder valve to get a good flow. If the flow stops, close the bleeder valve and step on the clutch a few times. Then reopen it and debris should come out of the line. The last time I did this A LOT of debris came out of the CSC system.
Judging by the color of your fluid, I think we can deduce why your clutch cylinder failed. Good video, well explained and direct. Would recommend using a flare wrench for working on the hard lines. I also find using a high temp fluid (Motul RBF600) works much better in the Z.
I had to replace both my master and slave cylinders this past weekend. The master cylinder was such a pain to get out, but the easiest way I found was to keep wiggling and pulling upwards above the abs bracket that is there. To install the new one literally took at most 5 minutes.
My clutch pedal is doing the same thing on my 370 but after a while of driving it comes back to normal. You think it could still be the clutch master cylinder?
I do, mine did the same. I don’t know if this is true so don’t quote me on this, but I think it’s the debris and dirty fluid is clogging up the leak in the master cylinder. Preventing fluid from getting behind that seal
Hey man. I wanted to say thank you for the video. I have a 2012 370z touring roadster and I just changed my cmc for the first time, all with help from your video. Greatly appreciated man!!!
@musokafairlady2012 Man seriously I had no clue what I needed to do I was freaking out. I can't thank you enough for this video. It was so helpful. I have watched most of your videos since I found the cmc replacement video. Love your content. Seems like you love your Z almost as much as I love my baby lol.
Ofc, I love musoka with every fiber in my body. This was my dream car for years. Now I’m modding it. I just wanna share that journey with other ppl and help ppl learn the things I had to learn on my own. If you want more content, definitely follow my instagram and tik tok. They’re both @musoka2012z posted a lot of good stuff of instagram today
@@musokafairlady2012 I feel ya man. I've been a Z fan since my first 280 years ago. I knew when I sold my 92 300ZX that it was a mistake and it took me years to get my 370Z this year actually. His name is Ezekiel aka Zeke da Freak lol. I've had 100s of cars but this is by far the best, greatest, favorite car I've ever had. Every single time I crank him I get freaking excited and want to hit a curvy back road. Btw my name is Channing. Would love to find out what all you have done so far and also ask have you been to Z Nationals?
My Nissan truck let me swap out the slave cylinder piston without having to remove the slave cylinder from the transmission... Sachs...... By the way a luk clutch kit can cause a lot of vibration on the slave cylinder
Not sure exactly what you mean but If it’s a threading issue, make sure the line is lined up to the threads correctly to prevent cross threading, check the threads to make sure none are damaged, twist the fitting bother clock wise till you feel it kind of click in place. Then turn it. Idk if this helps
Ain't no way you got that it in that easy. I'm trying to get my replacement in, and I can see the end of the lower stud, but it won't come through enough to get the nut on. Did you loosen the bolts on the bracket for the brake line distributor there? the big block that gives a bit when you bump it. Mine doesn't wiggle that much, but sure would be nice if it did.
Took about ten minutes of wiggling and pulling. It was difficult to get out but after a bit, it came right out. I didn’t have to take anything else off
No, the master is what was replaced in the video. If you have a 370z, the slave cylinder is on the inside of the transmission. Some other cars may have an external slave mounted to the outside of the transmission, but they’re not the same
hye broski. just got my Z and i strongly recommend upgrade your slave cylinder. Just had mine blow and i only had the car for 1 day. had to drop my trans a total of 3 different times because the previous own had put a weird clutch in it. as well as having to deal with combatablity issues. I strongly recommned if you dont want to have to deal with anything like that in the future get started on replacing and building your whole trans. upgraded clutch, flywheel, and pressure plate, and slave, your master seems to be done already. Good job man keep up the great work
Hey I upgraded everything but My master cylinder. The pedal has pressure but I cant get into Gears when the engine is running. Can someone give me an advice? Do I have to bleed the MC separately?
can you help me? my clutch is stuck to the floor and i see leaks but at the same time i was able to get a running start and still switch gears to drive it home to park while my clutch was stuck on floor what could be the main problem i have
Where’s the leak coming from? If it’s coming out of the transmission, your clutch slave cylinder went bad. (Which is common) if it’s coming from a line then just replace the line and bleed the system. If there’s fluid in the cabin, it’s probably your clutch master cylinder.
Hey man, would you have the old CMC on hand? From the mounting flange to the back of the body, how long is it? IE whats the amount it sticks out of the firewall? The 370Z CMC looks short enough for my application. Thanks!
How did you determine that it was the master and not the slave? Mine randomly losses pressure when changing gears but repressureizes if i let off immediately and give it a vew light taps.
Honestly it was an educated guess and process of elimination. It had to be one or the other and I’d rather try and replace a part that’s about $100 before dropping the transmission and spending around $500 give or take.
Basically I bought this 6mt g37 coupe and I absolutely love it. But I need help from u. I used Zspeed's CMAK stage 2 clutch kit with the CSC delete initially because the clutch fluid reservoir was empty and it wasn't able to go into gear. (my mechanic installed everything) This was able to get the car moving again. As soon as I got that settled, a couple of weeks later I noticed fluid constantly showing up under my driver's side carpet after driving. So we replaced the clutch master cylinder because the fluid was constantly emptying and I had to replenish the reservoir every 2 weeks to a month or so due to the leak under the driver's side carpet. Now, I'm noticing that my new clutch master cylinder tends to do the same thing when it's humid out. It will lose pressure overnight, and it's a hit or miss with the fluid leaking under my carpet. Some days ill just need to pump the clutch to get the pressure back, but other nights when it's rainy and humid out and I check the fluid it would be completely empty, and my carpet absolutely drenched. I'll also notice with the new clutch master cylinder it loses a little bit of fluid if I drive the car with spirit. Did the new clutch master cylinder break? Or is there an entirely new problem? It's literally hit or miss whenever I step in and try pushing the clutch. Thank you! tldr; clutch fluid shows up under the driver's side carpet what do I do if I already replaced the master cylinder
From what it sounds like, you may have bought a defective CMC. The only thing clutch related in the car is the CMC. Then it goes into the engine bay, where lines will run to the CSC on the transmission. If u have fluid in the car, I’d say it’s the CMC. If u we’re losing fluid outside the car and ur CSC was just replaced, I’d say you have a leak in ur lines. And since it’s inside the car there’s no way it’s the CSC. It sucks, but sounds like you may need to replace the CMC again and get it warrantied. This is just personal knowledge and experience. Other mechanics may say otherwise. But that’s what I would do in ur shows
I don’t know what you guys call it over there but in the UK it’s the biting point but mine basically feels weak on the way up. Is that CSC on the way out of does the master cylinder need changing? Idk how to really explain it lol
Different mechanics may have different opinions, but from my experience with my 370z nismo and 370z base this is the way I tou let shoot it. I check the Clutch fluid reservoir under the hood, if there’s no fluid missing, replace the Master cylinder first. That should fix it. If there’s fluid missing, walk the lines from the reservoir to the transmission. Make sure there’s no leaks. If there is, just replace the line. If there’s no leaks, see if fluid if dripping from the transmission bell housing. If there’s fluid missing from the reservoir but no leaks in ur line, I’d replace the internal slave cylinder. If you’re leaking from the Bell housing, that’s also the slave cylinder. I’m not an expert, but tho sis what I’ve been living by and it’s never failed me.

What if you bleed the line and barely any fluid comes out?
Is there fluid in the reservoir
I keep adding fluid into the reservoir but it just going back to E
I replaced my master cylinder and taking it to the shop to change the slave and upgrade to a metal one instead of the OEM plastic slave
@@alexrosas690 yes it was prolly the slave leaking inside the transmission. The CSC elimination kits are usually the way to go.
Should have replaced the the clutch pedal with an RJM adjustable. Shit made a huge difference on my g
Didn’t know that! May do that just cuz
My Nissan truck let me swap out the slave cylinder piston without having to remove the slave cylinder from the transmission... Sachs...... By the way a luk clutch kit can cause a lot of vibration on the slave cylinder
The hard line that goes into the master cylinder is giving me issues how did you go about that

Nipple?
For the drain?
@@musokafairlady2012it is shaved off
I’d have to see it. But I’m pretty sure those can be removed
@@musokafairlady2012if I remove it do you know if I can replace the nipple with a new one

@ I just finished installing my, thank you so much. Your video was a big help.
How did you get it out lol I’m having issues because it’s no space
Took about ten minutes of wiggling and pulling. It was difficult to get out but after a bit, it came right out. I didn’t have to take anything else off
@@musokafairlady2012I did this once a few years ago on my g37. I remember had to loosen the abs module to squeeze it through
So is the clutch master and the slave master the same thing?
No, the master is what was replaced in the video. If you have a 370z, the slave cylinder is on the inside of the transmission. Some other cars may have an external slave mounted to the outside of the transmission, but they’re not the same

Haha thanks bro😂🙌🏼🫶🏼
Where was the fork set on the master cylinder...how many threads did you have left on the fork before it could fall off..that's important to mention
Hey man, would you have the old CMC on hand? From the mounting flange to the back of the body, how long is it? IE whats the amount it sticks out of the firewall? The 370Z CMC looks short enough for my application. Thanks!
I’m so sorry! Unfortunately I threw it out about a month ago so I don’t have it anymore
my micrometer says 2.084 inches because of the seam. You could sand the seam down to make 2 inches.
