I'm just going to try and post relevant information in this thread for a hopefully quicker response.
6-8 months replaced clutch, felt great. About 2 months ago the clutch would occasionally sink once or twice and would feel fine. But since then it has become worse. 2 days ago that was it, couldn't change gears, clutch would sink 100% of the time. Today I pulled back the boot on the slave cylind and watched about an ouce of black dirty fluid pour out. The fluid in the resoviour was also black. So I bleed the system and its semi drivable but clutch does sink every so often.

Please tell me its just the slave cylinder and not something worse. Any know what's going on?

 

If your slave cylinder is leaking then you need to replace it.

You should also look at the boot for the pushrod of the master clutch cylinder down behind the clutch pedal and see if its leaking there too. You may need to replace both. Then bleed the system.

 

Thanks, The master cylinder looks good, I see zero fluid behind the clutch or so It seems its just the slave cylinder. Thanks should I check anything else before I order the parts?

 

I don't usually suggest parts store parts but for this it wouldn't be a problem using parts store slave cylinders. I am currently using an autozone slave cylinder on my dd. It comes with a lifetime warranty and I haven't had issues with mine since i bought it 2 years ago. I would suggest putting anti seize on the bleeder bolt.

 

Swapped it out today, but still have weak pressure when I engage the clutch and sticks. I'm sure everything was done correctly I even double checked master cylinder, lines slave cylinder and linkage. I still still the hissing sometimes. I even bleed threw a whole 20oz bottle of fluid. Last 15 ounces I saw only an occasional mini bubble. I'm getting irritated!

 

Just because the mc isnt leaking its still possible its bad.

First check for leaks.

 

Did that, went over ever part, no leaks and zero fluid behind the pedal in the boots etc. I'm stomped!
