Hello everyone. The other day it got real cold here overnight. In the morning when it was time to go to work, I had no clutch. The pedal hung loosely all the way down. I checked the master cylinder and it looked empty. I filled it with brake fluid and spent about 10 minutes pumping my clutch pedal by hand. About the first 40 miles I drove shifting like this: clutch, neutral. Pull clutch pedal back up with toe. Stomp clutch pedal about 5 times, pulling back up with toe if necessary, put in gear. After that it's almost back to normal, just a bit mushy. A guy at work told me I need to replace the slave cylinder, because the 40+degree drop in temperature shrank the seal in there. Well, I don't know what shrank where what do you think happened?

 

been there and done that. I had no clutch one time and found my master cylinder bone dry. A clutch hydraulic system is like a brake system, so you'll probably have to end up bleeding the clutch line at the slave cylinder because you got air in it. To me, this was a warning of impending clutch failure. this happened to me twice and the third time I was completely screwed over because the throwout bearing was shot and wasn't allowing the clutch to release. this might be what's happening to you. if the clutch isn't releasing, the release lever isn't pressing the pushrod back into the slave cylinder and in return, not allowing the clutch pedal to come back up. I'd check into it. start by bleeding the hydraulic line the same way you'd bleed brake lines. but I know exactly what you're talking about. it was push clutch in-go to neutral-pump the clutch until enough pressure was built up. when the clutch finally took a dump, I'd go to bleed the lines and when I pressed the clutch, the slave cylinder shot the pushrod across the street. there was no tension on the release lever. I got to the point where I could shift without the clutch. I can do it in my sentra too. but you gotta know exactly when to do it.

good luck with it. I dumped $550 to have a clutch replaced, after having it towed. now I got clutch problems in my sentra but it's not a hydraulic clutch. when you press the pedal and release it, it sticks for a second or two. genuinely annoying.

Thanks, it sounds bad but at least I know. I'm not good at no clutch shifting

 

this has happened to me as well....you need to replace your slave cylinder and possibly the hose going to it (look for leaks). Then bleed the system. Its really not that big of deal, and you can get around if you need to until you can get the slave cylinder by just filling the master cylinder and then bleeding the system.

 

Yup, found the leak, right from the slave cylinder. Thanks y'all!

 

One thing you might consider. There is a bracket the clutch line goes through. A different part of the line likes to chaffe on this...and overtime causes the line to crack as well. While your in there, you might try putting in a new section of line there as well as maybe replace the flexible portion of the line.
