Default Hydraulic Throwout Bearing: How to bleed?

How do I correctly bleed a McLeod Hydraulic throwout bearing?

I fired up my Cobra for the first time today (YAHOOOOOO!!!). Straight headers, no mufflers---just wanted to introduce myself to the neighborhood. Cobra runs great, and it was a thrill just to hear some life in it after working on it for so long.

However, I don't know what I'm doing when it comes to bleeding the hydraulic throwout bearing. I pumped it up, first by hand from under the car, and bleed the Tilton master cylinder first. Then I had my brother pump the clutch slowly from inside the car (I've only got two hands...). He'd pump it, and then I bleed the air out (not absolutley certain I got all of it, but...).

Am I doing this right?

I keep thinking that if he holds the clutch in, this should be pushing the HTB out, but if I release the pressure by bleeding it, the HTB is going to collapse first (as opposed to the pedal pushing in).

I'm not sure the "brake bleeding method" will work in this case.

I'm confident in my setup. I measured and adjusted the offset myself. I have the "bleeder line" on the top of the HTB, so presummably air would go up to the bleeder line.

Need some expert advide, or at the very least some sort of acknowledgement that I'm doing this correctly and just need to patiently continue.

Thanks in advance for your help,
Cheers

And yes, the Cobra was REALLY LOUD and I LOVED IT!!!!
