So i searched threads on clutch master and slave cylinder issues.

My 02 just started fussing. I blead the line a couple times then topped off the reservoir. Now my clutch has no pressure at all, i can literally tap it with my hand and it'll just drop to the floor and stay stuck. What Im really trying to find out is, if anyone knows its the master cylinder? If it is, Im going to change it, i remember the first owner saying he changed the slave hose cause it was leaking but i was guessing he probably didn't bleed the line. Now, Im considering the master cylinders life span is shot. So we found out problems and symptoms,i need help to confirm.

1. Blead the top slave
2. Pedal has no pressure what so ever.

 

run a direct line from your master to the slave cylinder... it cost me less than $5 to do mine... I just used regular 5ft brake line with an adapter for the slave cylinder... the dampening clutch system on the maximas is a joke... there are so many points where hoses are connected and it just a matter of time when it begins to leak... had mine for over 2 years now... no problems what so ever and clutch petal actually feels better and more responsive... bleeding the dampening system is a just too long of a process

 

Would that void everything else?

 

So i was only bleeding from the top and noticed since I've been bleeding, there is no more pressure in the clutch at all. Before i bled it, it still had pressure before it got stuck at the bottom. Now Theres no pressure at all. Anyone know Whats going on before i really have to spend money and buy a new clutch master cylinder.

 

Keep on bleeding bro lol, I had to bleed mine once for over an hour before i could get any pedal feel back. Or get a stainless braided line and be done with it it's up to you. If you bleed it 3000 times or so and still have no pedal check movement of the slave cylinder. I replaced both at once just to be sure and they were pretty cheap right from Nissan. Once you get air in that jungle gym of hydrolic lines it's a b!tch to get out.. Good luck

 

Thanks, it sucks cause Im literally bleeding it by myself. So Im opening the valve and bleeding it then closing and pulling the pedal up and doing it over and over.

 

You need two people for it to be effective man. Wait and get someone to help you and bleed it like your mad at it. I use to wedge the a baseball bat between the front of the seat to hold the clutch pedal down while i cracked the bleeder. Also make sure your pushing the pedal to the floor and pulling it all the way out with your hand.

 

i just moved to l.a so Im by myself :/ Im pushing it by hand and pulling it back up by hand. When you were bleeding it, did you open the valve after every pump or did you pump the clutch till there was pressure?

 

Bleeding the clutch is a bish. Having a string tied to the pedal to pull it up when you bleed is a big help, and as others have said, have a friend help you. It too me and and friend probably 2 hours to get all the air out.

 

I do like 30 or so pumps and then on the last pump you need to find something to hold the clutch pedal all the way down while you run and crack the bleeder(make sure you tighten it up before you start pumping clutch again) Then repeat until you get resistance back in the pedal and it springs back at you.

 

I am new to the site and need to sell my parts fast. I have a 3.5 from a 350z with computer (less than 100,000 on engine) and engine harness with a/c compressor, power steering, and alternator still bolted on. Also has 6 speed transmission bolted to it. Asking $2000 for all. Call Jesse at 678 544 2246 or 678 435 4735.

I also have all 4 doors with tinted windows Driver door does not have regulator in it. All heater core and air boxes and Rack and pinion. Brake master cylinder and Clutch Master cylinder are here! Also Back bumper and trunk lid. Driver headlight and instrument cluster showing 167,000 I believe.

 

Wrong place to post this. If you have something for sale, post it in the appropriate classified section of the forum.

 

Lol @ jayyjayy

 

JayyJayy that sounds awesome but i think you should post it to the for sale classifieds thread.

 

So i pumped the clutch for literally an hour and no luck. I barely felt pressure at the bottom and when i did, i felt a little relief but nothing more than that. I think the master cylinder is out, any takes anyone?

 

when you are crack open the bleeder, any fluid come out? I know you mention you are doing this by yourself, so when you crack open the bleeder, run inside and step on the pedal, then back out again to close the bleeder, do you see a large amount of fluid that have been squirted out? after you close the bleeder, look at the clutch fork/slave cylinder and see if you can manually push in the slave cylinder in and that it is not fully extended, ( this just rules out any issues with the throwout / pressure plate). If the slave cylinder is fully extended and the pedal springs back up when you push the slave in then you have an issue inside the bell housing.

If you are cracking open the bleeder and no fluid or very little fluid is coming out on each pump, you probably have a bad master.

not sure based on your first post, what happened first. did you lose pedal pressure then started bleeding to try to fix or did you start bleeding the system after replacing a busted line and then started having issues afterwards.

 

I started bleeding cause i have no pressure in the pedal. Fluid squirted out when i cracked open the bleeder at the top. I know my throwout and pressure plates good cause i recently changed it.

 

The previous statement about the slave hose was referring to the owner who put a new one in. I did notice the my catch points weren't consistent before.

 

if you don't have a second person to help you, you might need to get your hands on a vac. pump. to help you bleed it by sucking the fluid/air out of the lines at the slave

 

I haven't even tried bleeding from the slave, I've just been bleeding fron the upper valve. :/

 

From what Im reading, it sounds like i have to keep at it and pumping the clutch for pressure.

 

try opening the slave cylinder bleeder and pushing fluid upwards through the bleeder. This will force the air out of the master cylinder end.

you need a device to push fluid up through the bleeder though


i use this, got it at walmart its a 2cycle gas mixer






its called reverse bleeding i beleive

 

I managed to get pressure in the clutch pedal finally! Now im pumping the clutch and using a 2x4 to hold the clutch in place so i can run up and bleed the valve. pressure is there and the clutch is springing back up but if i push it slowly, it loses pressure and sinks to through bottom again. How long does it usually take to have the pressure at the top of the clutch again?

 

I guess bleeding does take forever. Finally got enough pressure to make it drive in gear but clutch loses pressure if my feet is pumping the clutch half way on down. I habe keep bleeding the bloody thing.
