clutch linkage?

[own3d]

well i was driving around last night and about a mile from my house i was going to shift to third, so i push the pedal in but the shifter wouldnt come out of second and i noticed that the revvs didnt fall off, so i let off the pedal and it stays down on the floor. so i yanked it out of gear a coasted the last mile home. i looked at the linkage inside the car and from what i can tell looks like its in working order, i didnt see it leaking fluid anywhere and the clutch master cylinder is still full. anyone got any ideas? the pedal is completely dead about 3/4 of the way down then the last 1/4 is almost to hard to push in with my hand. the clutch doesnt disengauge at all. i really need to get this fixed today so i dont have to bum a ride off my parents in the morning.

Try rebleeding the system you probley just have some air in it.Or it could also be you slave,Mine did the same thing right before it went out.

yeah, im thinking its the slave cylinder, i looked at my friends assembly and everything looked the same except the little boot that goes around the linkage where it goes through the firewall was dry, on mine its covered in some fluid, so i guess its off to get a new slave cylinder.

also the clutch system just uses dot 3 brake fluid right? i know it did on my mazda b/c the clutch fluid was acctually taken from the brakes master cylinder so id assume so but just asking for reassurance

[9240sx]

Yup,Dot 3

first off i was mistaking the slave cylinder for the master cylinder. but i finally got off my lazy *** and replaced the master sylinder but now im really confused. i take the old on out, put the new one in, get it bolted down and reattached to the clutch pedal, fill it up with fluid and start pumping the pedal and get nothing, pedal is completely limp. so i take off the cap and the resivior is still full. so i took off the line going from the cylinder down to the slave off and pumped it once, sure enough it shoot some fluid out and the resivior went down, so i tightened the line bakc on and pumped it some, nothing, fluid didnt drop and the pedal never got harder. anyone got any ideas, when i take the line off the cylinder itll shoot out the side but when its attached it wont push it through the line i guess?

If you got some of the air bled out try adjusting the shaft where it connects to the pedal. I had to thread mine almost all the way out to get it to pump up some pedal and then later readjust it in to keep the clutch from slipping when driving. u can turn the shaft real easy with plyers after unlocking the lock nut. the hard part is lying upside down with your head stuck under the dash and your butt half way up in the drivers seat. Gettin out again is a strain too.

yeah, being 6'5" and weighing 290 doesnt make it any easier. its supposed to be less windy and warmer tomorrow so hopefully ill get it done tomorrow

WHOa.. this same thing happend to me lastnight, but mine works still. Maybe im loosing pressure when i drive longdistances w/ out pressing clutch.

just off the freeway/slowwwdown for the train trax/second gear fine/buncha cars behind me/speedup time for 3rd/!screaming wtf is the MTHERfk3r!/:thinking feels like automatic wheres the clutch where could it have gone. did it go through the floor wtf:/)(cars honking)(/stick it in neural and coast to a spot to pulloff. the pedal was on the floor, just like it was SUPPOSED to be there or somthin. pulled the pedal back up w/ my foot and went on about my buisness. for somereason i really didnt think about it tooomuch. but yea theres probably a real problem here.

own, Did you fix it yet?. If so, did my two bits help? There is two bleed valves underneath. One on the line junction block and one on the slave cyl. I bled the junction one first and then had to keep going back and forth on both until all the air pumped out. Then I had to adjust the master cyl shaft to the pedal out, under neath, like I said, until I got it to pump up. You'll end up with a crick in your neck or back by the time you're done.

lol, your sig like directly applies to me.

no i havent gotten it done, ive been meaning to do it everyday after work but i usually have a shower and end up taking a nap and by the time i wake up its cold and dark out. i definatly wont be doing it tomorrow but i WILL get it done either saturday or sunday. im tired of driving my ****ing mazda so ill get my brother to help me this weekend. 1 question though, how do you adjust the shaft on the cylinder while its bolted down? push the pedal down, un-pin it, then adjust it i guess???

[own3d]

ok, well it ended up raining for almost a week straight but i finally told my dad i was taking over the garage, got it jacked up opened the bleeder at the junction valve and bled it about 5-6 times, filled up the master cylinder, opened the valve on the slave cylinder and nothing, so i closed it had my bro pump it a few times opewned it, pushed pedal down, nothing..... did this 5-6 more times before getting pissed and stopping for the night, didnt start till about 10:30 and my brother's supposed to be in his room by 10. any ideas on why itll come out of the junction box and not the slave cylinder? maybe the line is clogged somehow?

Go up under the dash where the shaft attaches to the pedal. Loosten the lock nut and turn the shaft out gripping and twisting it with a pair of plyers to make it where it will be longer. If you got all the air out correctly it should pump up now.You may have to readjust later if you have it too tight because the clutch will be engaged and slip.

ok i spent alot of time tonight adjusting the lengths of the pedal and got it to build up pressure but i think i need to readjust it to make it a lil shorter cause the clutch is still slightly engauged all the time. but im also afraid that the online nissan tech might be right and the pivot ball might be broke or the fork might have fallen off the throw out bearing. cause the little fork that comes out of the transmission wiggles some. so since im lazy, worthless and dont have anywhere i can drop the transmission i might have to break down and make my first trip to a shop to let someone else work on my car....

One more quick little you guys might want to think about. Mine started loosing preasure a couple years ago. I got lucky. My father-in-law was a mechaninc. I replaced the bleeder valve before I tried bleeding the line. Sometimes they get stuck open. Think about it. They're on the bottom of the car ssecond only to tires for being closest to the road. They pick up alot of stuff. I spent 3 weeks screwing it up before I sucked it up and asked him for help.
