Clutch no longer disengaging?

[Ls2monaro]

Just ran into this problem about an hour ago... very odd, where the clutch pedal goes all the way to the floor and is not disengaging the clutch.

I just bought this damn car a few weeks ago and little problems have been popping up here and there. Basically, when I first got the car the clutch wasn't disengaging well, so I adjusted the clutch pedal rod and that made a HUGE difference. The car then drove just fine.

Then earlier, hopped in the car after it had been sitting a day and the clutch pedal had zero feel to it and went straight to the floor, then made a loud clicking noise. So I checked the reservoir, totally full, no leaks. Then climbed under the dash and checked the rod, still in place. However, while I watched the rod and pushed the pedal, it went in half way or so, then slowly sunk in all the way. Then the spring for the pedal made the big *click* noise.

Can't shift into or out of gear while it's running and definitely can't drive it anywhere like this....

wtf?

I've had this happen twice. Once it was the slave cylinder spewing oil (have you checked that for leaks or if it moves at all?) an the second time it was just a simple adjustment of the master cylinder rod.

If there's no leaking at both ends and the slave moves back and forth, it could be that the pivot ball needs shunning or a broken release fork.

Here's a good video of how to adjust your clutch which is most likely your problem http://www.youtube.com/watch?v=vYJxQyjIhUw&feature=youtube_gdata_player

check the boots of both the master and slave cylinder. if any liquid is present, that cylinder is shot. If one cylinder is shot, it is HIGHLY reccomended to change both at the same time to make the wear even. PM with any questions

Alright, I watched the video and that had a very good tutorial, thank you.
However, I'm still a little confused. When I adjusted the clutch pedal rod, I spun it damn near all the way out (torward the firewall), which I figured wasn't good for it, but it seemed to do the trick.
--Now after watching the video, the guy says that with it adjusted too far the fluid can't get back into the reservoir and the slave cylinder becomes "non-self-adjusting".

So, when I initially adjusted that rod, wouldn't it have ceased to work right then? i.e. a week ago or so? It was just very odd that the clutch was working great, then parked the car, and suddenly it just stopped working..

Also, the loud *click*, or whichever, is definitely the clutch pedal assembly spring popping off or something....and it happens every time I push the pedal down, and then it sits on the floor until I pull it back....

ugh... could it maybe just be the pedal assembly f*&%$ing up?

This was my problem. Im not sure about 1g.

On very light foot pressure on a 2Gthe pedal drops to the floor all by it's self. ?? Yes. The little rubber seal in the pic above gets a little nick in it or a piece of dirt under it. On a regular pedal push, the seal seals fine and the clutch works normally. On a very light push, the seal does not seal well and fluid will bypass it. Since the 2Gs have a heavy assist spring, the additional assist is enough pressure to keep the pedal going towards the floor all alone. Quite disturbing to watch. Replacing or rebuilding the master cylinder will fix this.

I replaced my master!

Do not adjust the rod. That's everyone's solution on here. Something cause the rod to do that. Adjusting it will only cover the problem. I learned the hard way!

Alright, so step 1 would be checking for leaks, bubbling, etc.

step 2. see if the slave cylinder is moving at all under clutch pedal movement

step 3. make sure that the slave cylinder can be pushed in by hand, and if not then adjust the pedal rod properly.

then when nothing else works replace the clutch master cylinder and slave cylinder? ...fml

Thanks for the info on that, unfortunately mine is not working all together, no matter which way I try to push the pedal...and that loud noise from the spring is very uncomforting...

Nobody has mentioned the throwout bearing... so +1 on it. If it came apart then this could be the issue.

Yes do this ^^

When this happened to me, it was the exact same thing. I was driving down the street and at one stop light, I suddenly could not disengage the clutch. Same thing, pedal to the floor, spring clicking, I adjusted the rod for maximum travel while still leaving room for the bleeder valve on the master and voilà! It worked!

Make sure your clutch release fork hasn't broken. It's easy to check. Just try to wiggle it back and forth and see if it's loose. If you don't know where it is it's right at the end of your slave cylinder and it's what the slave cylinder rod pushes on. It goes through a rubber boot (if yours is still there) and into the transmission bell housing.

Now that I think about it, check for free play in your pedal assembly (cltuch pedal). If there is free play then the bushing in your pedal gave out like mine did about 2 months ago. if this is the case, you have to remove the assembly and have it welded together for a more secure fitment.

Alright you guys, thanks for the info on all of this. I'm about to go out to the garage and see if I can't figure this all out. I'll keep everyone updated too.

Well, I got under the car and found that the slave cylinder was leaking, just a bit though under pressure. That and the boot was pretty rough. The rubber plug for the fork was in place though and that mechanism felt fine.

So I went ahead and ordered a slave cylinder and a master cylinder.... Installing tomorrow. *crosses fingers*

 

[Ls2monaro]

Ended up fixing it a week ago or so and thought I'd post a conclusion

Just got the clutch master cylinder and slave cylinder from autozone.. I know, not oem, but with lifetime warranty so whichever. That and adjusting the clutch pedal correctly definitely fixed the problem

dude, once that goes on, if put on right, it wont come off.
