Need help! Clutch Master Cylinder Bleeding.

[96_WhiteBird_Manual]

Hi,

I bought an AC Delco clutch master cylinder 18M2232 from gmpartsdirect.com

I had my mechanic install it two days ago, and it does not give any pressure.(If I press the pedal, it does not return.) :(

We bled the system. (repeated pumping the pedal, then opening slave cylinder bleeding valve.) There was no air coming out of the valve.

Then we used a new oil extractor to suck the fluid out, but still it's not working.

Is there any special way of bleeding or is master cylinder defective?
Changing master cylinder looked simple, but this drives me nuts. [img]graemlins/crybaby.gif[/img]

I would suspect the master cylinder is faulty. :(
