If the cylinder is leaking hydraulic fluid or air or whatever its not working real good.
If the cylinder goes all the way thru its stroke and what ever it is activating doesn't activate, the cylinder is likely not working.
If the piston in the cylinder is not (will not move) moving at all it ain't working.
If your working on a car made by British-Leyland its time to trade for something asian.
The best thing to do is replace it with A new or rebuilt unit. This is how you determine witch part is bad, If you are losing fluid its likely the slave cylinder, If the fluid is still there but the clutch is not working then its likely the master cylinder.
my clutch is not working ..think the slave cylinder is bad ..135 , 000 miles ..
If the problem has been getting worse over time than it is your clutch. If was sudden, then it is your slave cylinder. Also, the slave cylinder will usuall leak fluid when it is bad. If your not sure and nobody else is either, replace the slave first. It is farely cheap and super easy to replace. I hope this helps and good luck!
In general they leak hydraulic brake fluid when they go bad.
Remember, keep the master cylinder full so you don't suck air into the slave cylinder. Then you put the fluid in the slave cylinder.
It has to be on the slave cylinder, not sure that was your question.

In cylinder
The slave cylinder for a hydraulic clutch is located inside the manual transmission bellhousing
Depends on what it is doing. There's only 3 parts really. The clutch disc itself, the master cylinder, and the slave cylinder. There is no adjustment. If the car still pulls itself but is difficult to shift or get into gear, it's probably the slave cylinder. That's at the transmission and disengages the clutch. The fork that attaches from the slave cylinder to the throw-out bearing may also be bent, and the clutch master cylinder may possibly be worn out along with the slave cylinder. You can determine if it is a hydraulic problem if you rapidly pump pedal a few times and it becomes easier to put in gear.
The slave cylinder function operates from hydraulic pressure received from the master cylinder when applied. In automotive hydraulics the slave cylinder can operate such functions as the brakes, clutch or any hydraulic operation.
