Guest bastaad525 Posted June 16, 2003 Share Posted June 16, 2003 I posted a while back that my clutch pedal keeps 'sinking', in other words that over time (noticeable after a week or so), I find that I have to push the pedal further and further down to disengage the clutch, until it gets to the point where with the pedal fully down I can't even put the tranny in gear. I had already replaced the clutch master cylinder, which I saw was leaking, but then the problem persisted. So I replaced the slave cylinder, which I could not see any leaking from, and now it's doing it again. I'm going to bleed the system today or tomorow and see if it gets better afterwards... I'm assuming it will, which indicates a leak but from where?? Is there that big of a chance that the replacements were faulty? I dont see any more leaks on either cylinder. I'm running out of options here...... am I gonna have to bleed the thing every week? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted June 16, 2003 Share Posted June 16, 2003 Is the fluid level dropping? Did you replace the soft line at the slave? It is not impossible that the slave that you got is bad. Was it new or rebuilt? Take it back and tell them it's bad and get a new one (under warranty) just to be sure. Also, make sure that the peddal adjustment is good. You should have about 1-2 inches of play at the top before the rod engages fluid action. Tim Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted June 16, 2003 Share Posted June 16, 2003 yeah there's about an inch of play at the top, my mechanic said he did replace the line, maybe he did not. the parts were rebuilt. and from what I can see it is not losing any fluid level at all, this is the part that baffles me the most.

Tim240z Posted June 16, 2003 Share Posted June 16, 2003 I would bet the MC is bad. Replace it under warranty. Tim Quote Link to comment Share on other sites More sharing options...
innerware Posted June 17, 2003 Share Posted June 17, 2003 Do yourself a favor. Don't go to a mechanic. Do it yourself. I am by far not a mechanic and I just replaced my master and slave cylinder. It was real easy once I had the right parts. Order them from British Victoria. Both will cost you 50.00$ US THe hardest part is taking out the pin that holds the pedal to the master cylinder. You will need two people to bleed it though. Once I had the correct parts it took me and my friend 1/2 an hour. Works great too. Sounds like it is your master cylinder too. I had the same problem a few weeks back. Good luck, Kyle Quote Link to comment Share on other sites More sharing options...
Guest Al 260Z Posted June 18, 2003 Share Posted June 18, 2003 Highly recommend Nissan OEM parts. Any slight premium in cost is more than paid back in reduced hassle factor and satisfactory long-term performance. Agree with above. Clutch master/slave/flex line replacement is very easy DIY project. Biggest hassle is finding a helper to hold pedal down while you open/close slave bleeder (repeat this 12 x).

Guest 240hybrid Posted June 18, 2003 Share Posted June 18, 2003 I went and bought a $25 self bleeder so I dont have to rely on others. Its a great tool, it will bleed brake lines, check vaccum, produce vaccum, and is a pressure gauge too(directions describe each very well). Its call myte vac if Im not mistaken. I have used this tool at least 5 times in the 3-4 months of having it. Invaluable when doing brakes and trying to find vaccum leaks. MSA has it in their catalog, but is cheaper at the local autozone. I would get one if doing it yourself, which I agree with everyone else, do it yourself. I have seen and experienced coming behind mechanics and fixing their BS. Save your $...and know its done right.

Guest bastaad525 Posted June 18, 2003 Share Posted June 18, 2003 heheh you guys must all have had some bad experiences..... normally I dont trust mechanics either but luckily the one I go to is kind of a different breed. I've been going to the guy for 6 years and have always been satisfied with his work. He charges like 1/2 what any shop charges, if not even less, and works from home. All this guy does are Z's, and I mean that literally, he wont touch anything else. So I dont feel this has anything to do with his installation, more likely it's just the parts having been bad to begin with. But I do appreciate the advice.... true I could save the $20-30 and do it myself, and if I replace the parts again I probably will do that.

Guest 240hybrid Posted June 19, 2003 Share Posted June 19, 2003 He probalbly does know what hes doing. I have had mostly bad experiences around here, but did finally find one guy that I refer friends to, and I used to use him too, but I started getting interested in mechanics and preferred doing my work in my time, not his. Saving the $ by doing it myself is cool too, now I can charge others for ME to do it also. I enjoy messing around with mechanical things and the gratification of fixing them.

innerware Posted June 19, 2003 Share Posted June 19, 2003 Oh, I don't mean to say mechanics are bad. My old one still answers my questions and had always done superior work. But it is nice to save even 50% of a normal job, do it yourself and have a little extra money for the next project. However you are lucky to have someone good you can trust.

mustard-z Posted June 19, 2003 Share Posted June 19, 2003 you could be sucking air into the system somewhere, check that the bleeder valve is tight, causes a heck of a problem. Quote Link to comment Share on other sites More sharing options...
Guest Al 260Z Posted June 19, 2003 Share Posted June 19, 2003 If the slave seal gets weak it will allow air in on the pedal up stroke. It will also let air in on use of the Mighty Vac. This gave me fits til I figured it out. Later, Al Quote Link to comment Share on other sites More sharing options...
Guest 240hybrid Posted June 20, 2003 Share Posted June 20, 2003 Check all the clutch line unions(threaded connections) I know if your brake unions are loose/leaking your brakes will sponge. Their really similar hydrolic systems, so I could see this happening if one of you clutch unions were loose. hope this helps Chase Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted June 20, 2003 Share Posted June 20, 2003 yeah I'm starting to think it's the lines themselves or where things connect..... replaced the master cylinder twice and just did the slave..... and still having the problem..... and I dont have the cash right now to shell out for nissan factory parts, especially since if that's NOT the problem, I'm REALLY assed out......
