Still confused regarding gravity flow

Thanks guys. I appreciate the insight. I'm still confused as to why when I disconnect the line at the slave fluid doesn't freely run out of the line (from the master) and onto the ground. Any thoughts? My master is full but fluid doesn't run out onto the ground...What's going on here? And how can I resolve it? Thanks for your advice.

this may not sound right but, every time i did any hydraulic clutch repair on any truck gas or diesel; even after i did get all the air out i had to keep pumping the clutch to get it to pressurize. The master cylinder does not have enough voluum to accomadate the whole system with a stroke or two like a brake system.

A properly bled and adjusted system is Always under pressure
so after you bleed the air out keep pumping, even if you have to manually lift the pedal.

It is not so much "the volume" as the throw on the M/C....the piston is under pressure and does not come all the way back, thus giving a shorter stroke and yes, less "volume"

bc6.9 please explain, if you reach under the dash and disconnect the cl. pedal arm from the m. cylinder push rod there is no pressure on the pin since the piston is back.

Ben-jamin,
The master cylinder linkage does not have pressure on it.
The master cylinder piston is retained by a C clip.
The piston should be against the C clip when the clutch pedal is out.
