Long Story Short
1. Changed my master/slave just because my fluid was ugly
2. Changed um, felt fine at first then Clutch started sinking in and you would have to pull it up with ur foot all the way in order to get a nice shift.
3. Then couldnt even get into gear
4. CHanged clutch with ebay stage 1 clutch kit
5. Shifts beautiful now, just sometimes the clutch sticks in and you can pull it up about an inch with ur foot. and if u dont then it feels it gets real deep.
6. i adjusted it really high and it springs backk all the way almost everytime
7. Now im here..

im new here. and ive read just about every damn post about the 240sx clutch not coming back up on every damn forum and each one says to rebleed but i did it so many times.

so i got a 90 240sx and one day i saw my fluid was dark and wanted to flush it. my uncle said might as well change the slave and master because he said he seen that the slave was leaking when i bot the car. ordered the combo on ebayand it seemed perfect the first night until i felt the clutch sink all the way in. after that i would have to lift the clutch up with my foot to get a nice shift. my uncle said it was the spring but it cant be. i drove it like this for like 2 weeks and then it wouldnt even go into gear! now im pissed as hell i cant even drive it. so i ordered a stage 1 clutch with fly wheel on ebay and had it installed(hella expensive and mother f's stripped a bolt on the starter when doing so and had to get another one)

it shifts so amazing now and feels great other then getting stuck after a couple shifts but now it doesnt affect the shifting but its annoying because i know i can pull up some of it. (i rebled it last week and bypassed the dampener box) but it still sticks a little bit.

help...

I'm sorry, but are you saying you are having issues with the pedal? Its hard to understand what you are saying.

Things to consider:
change out slave cylinder
inspect pivot fork

so its going into gear now and shifting ok? but you're pedal is still not coming back up? Seems like you have air in the line still. Check the slave again like walper said.

but yes after changed the clutch it shifts fine nd normal but once in a while it still sticks to the floor and almost a whole inch u can pull up with ur foot. but if u dont pull it up it still shifts fine.

EDIT: btw master and slave are new and changed and new clutch

it happened to me after i changed master/ sslave tho and they said my pressure plate was the reason it was not going into gear. got a clutch kit and now it shifts perfect better than ever but it stills sticks a bit.

my pedal had a lot of play and it was engaging really low how i liked it. and at that time it wouldnt come all the way back enough to hit that lil sensor thing so i readjusted it now it engages really high but most of the time it comes all the way back up because of this adjustment and is able to hit the sensor. theres is not that much play anymore just a bit

***someone told me to adjust it to factory settings, then rebleed it very good and onceits rebled really good u can aadjust the pedal to however u want it.

it cant be air in the system because i bled it hella times and even had my boys shop bleed it... unless we just suck at bleeding 240's.... im thinking something with the clutch assembly is broken.... ill take the clutch pedal assembly out if it comes down to it in order to rule that out...

You have to bleed the ever living shit out of the clutch lines.

have you adjusted your clutch pedal? how much "play" is in the pedal before it begins engaging?

there is alot of play before it begins engaging.... its kind of annoying. dont know an exact number but id say atleast 2inchs or more

sounds like you need to do that, its a 12mm ( if memory serves me correctly ) find your pedal and the rod coming out of the assembly into your master cylinder, undo the 12mm nut and turn the rod counterclockwise until you eliminate some of the "slop" in the pedal.

Should help you when you are bleeding, and give you a more consistent engagement point. good luck

What i did when my slave went out was;
-Change slave
-Change master
-Loop the distributor box (the one with bleeder from master)
-Direct connection from master hardline to slave soft line

Seemed to work instantly and hadn't have problem since.

Your pedal is sticking in when you push it down?

There must be a clog in your lines or you dont have enough pressure.
Do you still have the bleeder on that box or did you snap off?

sounds like you have an internal leak in your master, is it a good brand or a cheapy ebay special? did you try vacuum bleeding it? and did you bench bleed your master?

Use the one man bleeders from autozone cost 8 bucks, that thing works! Air in the system!!! Are u connecting a clear hose to see if there is air? How are u bleeding it? Pump, pump, pump, hold, open the bleeder-still hold, fluid comes out, and then close, then release pedal, then start pumping again... But get that one man bleeder even easier

I am guessing your car is stock, you replaced the master clutch cylinder and clutch slave cylinder. You bled the slave cylinder and made the adjustment to the clutch pedal which I was about to say but some one mention that already.
Next would be did you bleed the clutch damper box (the one that is in-line from the master to the slave clutch cylinders)? If you haven't, then do that, you have to bleed that clutch damper box also otherwise you still have air in the system. You can use whatever system you want and bleed till your blue in the face and it still won't do diddly if you don't bleed the damper box and make adjustment to the master cylinder rod.

You can get rid of that by getting a ss braided line to by-pass that box and in the future it would make clutch bleeding easier and make the clutch feel stiffer.

Just my thoughts ^_^

yes everytime i shift and go into gear and take off itll stick in and if u dont pull it up itll sink in pretty deep and feel like its almost on the ground but u can still shift.

bleeder on the dampener box? or what bleeder?

thanks bro, but i bypassed the damper already bro... i just kinda bent the line and got it to attach to the slave... i bled it after i did it but maybe i need to bleed it harder... now i can just bleed from the slave directly... and also i will try the master cylinder bench bleed or get the one man bleed...

bench bleeding you take a hose from the outlet on the master and run it back into the resivour and just keep pumping it till you cant see any more air in the tube, and vacuum bleed is a little suction thing they sell at autoparts stores that you hook it up to the bleeder and keep pumping it till there is no more air. you can google both to get more details

thanks bro hopefully i will have time to do this today... have a damn essay to write ahhh... aye but if i drive like this and maybe even readjust my pedal really high will it fuck anything up??? i never smell anything burning when im driving i always have window down to make sure im not burning the clutch since it is myfirst stick, but ive gotten the hang of it by now

cbcm2435

i wouldnt drive it like that just for safety reasons, when ever you are replacing a master cylinder whether its brakes, clutch, or a hydro ebrake, you always want to bench bleed it to make bleeding alot easier

cbcm2435
03-04-2012, 06:50 PM
and since it didnt start happening until you replaced your master and slave cylinder, one of those has to be your problem if bleeding doesnt fix it

okay so i adjust the pedal low and it has alot of extra play that should not be there i mean the pedal is able to move an inch before the pressure builds. if i adjust the rod higher then it pops up all the way most of the time but will still get stuck eventually... im gonna put a new master and then bench bleed it.

(is it possible the actual pedal assembly is messed up? im scared to disassemble it and then have hard time putting it back together lol..)

i changed the master cylinder and its alot better because the one i had was leaking a bit. but i have a question about the small button the clutch presses when it comes back up
what does it do? it comes up most of the wayb but not enough to press the button

is that bad that itr does not touch it???

That switch is for the cruise control system.

If it's not pressing the switch, the CC will not activate.

oh okay so not bad.... if i ever want the cc on ill just pull my clutch up like a cm and itll be good thanks bro!
