Bleading Clutch Cylinder System

[hein]

I know it's supposed to be factory sealed but I took it apart anyway. Is the disk in series between the master and slave some sort of accumulator or pressure damper? Haven't figured that one out yet. I've also been considering ways to bench bleed air from it when I put back together. Thanks for sharing your knowledge.

What does that mean? There is a damper in the clutch hydraulics. I don't try to bleed this system but, if I were to try, this is how I'd do it.

It is a "damper". I asked this a few weeks ago- it reduces vibrations somehow. I haven't got around to cutting my spare one open to see what is inside it.
There is a way to "bleed" the system, per the post above.

Also, try a Mity Mite to vacuum air from the M/C, using suitable adapters, this was also a TSB that someone quoted.

Bleed Sealed master/slave in-car with no mess!

It's clean, dry, and doesn't require disassembling the slave.

I found it easier to bleed with the whole thing installed, with the slave hanging off the trans.

--- Twist the slave cylinder off the transmission, and point it vertically, with the pushrod facing the ground. With the cap off the reservoir, SLOWLY depress pushrod into the cylinder about an inch while watching the reservoir for bubbles. Repeat process until air bubbles no longer appear, usually about 10 to 15 strokes. With the cap still off, slowly press the pushrod in far enough to reconnect the bands on the retaining strap, if not already broken. Reinstall slave and replace the cap. Using short quick strokes, press the clutch pedal 20 to 30 times or until pedal is firm. Under normal usage, small anounts of air remaining will purge itself from the system. ---
