Clutch Slave Cylinder Removal & Installation write up

[mchkc240]

It's really easy to replace your slave cylinder.

Thing you will need:

Some basic toolsA new slave cylinder(From Autozone or Kragen. Get the one with life time warranty so if it starts leaking after coupes years you can get a free replacement)A milk jar (Or other containers that can be used to collect the brake fluid)A 2 feet vinyl tube

Time:Less than 1 hour (Including the bleeding time)

Cost: $26 - Slave Cylinder (I heard you can get one for 15 from Autozone) $3 - Vinyl tube. Total = $29

Step 1: Bleed the clutch system a little bit until the slave cylinder piston does not move anymore.

Step 2: Disconnect the bolts that hold on to the slave cylinder



Step 3: Disconnect the flexible fluid hose from the slave cylinder (You should not see too much brake fluid since you bleed most of the fluid out already) Be careful do not twist the flexible fluid hose too much. Turn the slave cylinder instead of the hose. Your slave cylinder will be able to spin freely since it's out.



Step 4: Connect the new slave cylinder to the flexible fluid hose

Step 5: Connect the new slave cylinder to the transmission

Step 6: Fill up the master cylinder reservoir tank and bleed the whole system again. Keep bleeding the system until there isnt ANY air bubble coming out from the bleeder valve. PLEASE MAKE SURE THERE ISNT ANY AIR BUBBLE INSIDE THE SYSTEM.

Step 7: Final Check-Ups (Make sure the slave cylinder rubber boot is on correctly. Piston is pushing correctly. Bolts, bleeder valve and flexible fluid hose are tight)

Then you are done! If you have questions please feel free to send me an email.

Hey there. thanks this helped for the most part. But I cant get the clutch to build any presure when i bleed it. I must be doing something wrong. When I bleed it i get no bubbles just some fluid. but there is still no clutch. Whats the best way to bleed it?thanks

have someone press the press the clutch while you are under the car. first, pump the clutch like 5 times, hold it down, and while holding it down, open the valve and close it really quick. pump it again, hold it down, open the valve quickly and close it quickly, and do this over and over for 15 minutes or so

Bleed ur slave cylinder until it sounds like it's not longer "spitting" or until you know there's no more air bubbles...Close it up. U should have no clutch feel at this time...There's another nipple that u have to bleed. The tubes run along the "passenger" side of the frame...(just so u noe the nipple is pointing straight forward towards the frontend of the car). Bleed it and you should get instant clutch feel right away! hope that helps!

Now would be a good time to get rid of that clutch damping box chit

[mchkc240]

Im glad that this could help you out. Other people already said the right way to do it. But I will just type out what it says on the FSM

A.Top up reservoir with recommended brake fluid (aka Dot 3)B.Connect a transparent vinyl tube to air bleeder valveC. Fully depress clutch pedal several timesD. With clutch pedal depressed, open bleeder valve to release airE. Close the bleeder valve.F. Repeat steps C thru E above until brake fluid flows from air bleeder valve without air bubble.



Hope this can help

yo this is so damn weird. i was just thinkin that tomorro im goin to take off my slave cylinder and i wanna know how to do it and im gunna search it. But i think this after i click 240sx/silvia link and im like damn it now i have to wait 2 sec and the first post is urs.

DOOOOOOOD DUDE You are so AwEsOME just for the timing.

[mchkc240]

[B-Boy DuB-L]

So... Brake fluid is used for the clutch?

Josh

[94_240sx]

Like ILikeMy240sx said, I heard you can get rid of clutch piping connector and U line. You can use stainless steel line to connect hardline and slave cylinder. That way you will have only one place to bleed. I also heard that pedal feel improves slightly. That's what I'm planning to do. If you anyone has done this, please shed some light on it. Anyway, nice write up...

Josh

correct

[DownSouthSlider]

this is awsome...just bought my new slave and i have a stainless steal line on the way!!! good job dude!! u should get a free nico shirt for this !!

[ralliart2k4]

Is there any way to bleed the lines solo? I will be doing this alone...and that seems like it might be a problem for bleeding the brake fluid from the clutch lines.

[Acecool]

1 man brake bleeder.. not pleaser....

cough...

Fill it half up with brake fluid, fill the master cylinder up with fluid...

open the screw at the bottom and connect the 1 man brake bleeder up it it..

pump the clutch 3 times with your hand - refill top - repump - half empty brake bleeder - fill top - repump... seal screw at bottom and test clutch..

should only take 1 or 2 minutes..

[ralliart2k4]

And if replacing the slave cylinder doesn't let me get the car in gear, would it be the master cylinder or the clutch?

[Acecool]

A good way to test is to see if the master holds pressure...

Take the hard line off, hold your finger up to that output and have someone press the clutch.. does it push your finger??? then it should be good :-)

Try the slave first, and remember do not push the clutch pedal if there is no fluid in the lines!!!!!! you will kill a slave that way!

[ralliart2k4]

Cool, thanks for your help again. I got someone on their way over here to help me bleed the lines and take me back to oreilly's if I need a master or...god forbid...another slave cylinder.

Gotta see if I can find a master cylinder R&I guide.

[Acecool]

R and I??

The master is the one at the firewall so you know because it controls the slave at the transmission :-)

Removal and installation??? Its very easy, unbolt the 2 10mm nuts, pull the pin out at the pedal, and pull out...

takes less than 5 to pull it.

[aivann90]

hey! this is off topic ., i have a 1990 240sx and the gauge cluster was stolen. is all of the 240 gauge cluster the same?? help me out dude i dont know what year of gauge cluster to buy. i cant find the one for 1990 year.

[JustDriftMore]

u gotta be kidding me ^

[rsagen]

can someone shoot me a pic of where the hardline runs? im doin a 5speed swap. i got the master on the fire wall but im not sure where to run the hardline.

thanks

[PapaSmurf2k3]

The hard line comes out of the master, goes kinda vertical, and then ties in with the brake lines on the firewall. This then runs over to the passenger side of the car, then goes down towards the slave cylinder side of the transmission.

I don't have a specific pic of it, but really you should be able to tell what's going on from just about any engine bay shot.

[PapaSmurf2k3]

or this:

[rsagen]

thanks x2. just wasnt sure if it ran on the inside or outside of certain places....
