bleeding slave cylinder

[jholl]

replaced clutch and pressure plate decided to replace slave cylinder, it was original to the car. can't get it to bleed out. can't figure out why. can someone help?

Not sure about your older model, does it have a combined Brake and Clutch master cylinder or does it have a separate cylinder for the Clutch ?

Can you be a bit more detailed about your problem, do you mean you cannot get any fluid to come out of the slave cylinder bleed nipple ?

What happens if you disconnect the pipe going in to the slave cylinder, does the fluid come out of that ok ?

it has a separate master cylinder. getting fluid through but can't seem to get all the air out,.have no leaks in system checked it dozens of times. don't know why all the air won't come out. had it close guy told me to drive it some, got to where couldn't change gears without pumping the pedal. so back to bleeding again. new clutch master cylinder a year ago, had no problem bleeding it at that time.

Assume you are using a piece of clear flexible pipe from the bleed nipple to a jar , are you sure the air is not getting in at that point ?  its easy to do if the  pipe does not seal.

Same if you open the bleed nipple too much, air comes in via the thread.

What about if you disconnect the slave cylinder and see if the fluid runs out of the pipe without air, indicating that the fault is in the new slave cylinder.

If air still comes out, it must be the pipe or master cylinder.

When all back together, and you press the clutch pedal down, can you see the clutch folk/slave cylinder piston moving ?   - wonder if your problem is more the clutch assembly ?

You replaced the thrust bearing as well ?
