Bleeding new clutch MC

[rickpaw]

I'm in the middle of swapping in a TR6060 to my Firebird, and I'm using the McLeod hydraulic conversion kit, with stock GM slave and Tick remote bleeder. The fluid is Wilwood brake fluid. The clutch is the Centerforce DYAD setup.

Below is the link to the kit I'm using.

For the life of me I couldn't get a firm clutch pedal. I removed the line from the MC, put the end into the reservoir, pumped the pedal and got all the air bubbles out, reconnect the line to the slave cylinder, bled the system until clear fluid (no bubbles came out), but the pedal is still soft. Pumped the pedal hard 10 times, and it firmed up the last 1/3 of the stroke. Cracked open the bleeder and the pedal sank to the floor. Did that multiple times, with almost 2 bottles thru the system. Now the clutch pedal sank to the floor, regardless how many times I pumped it. Checked the reservoir and filled it too, as the fluid level went down a bit.

I checked all connections, and they're dry with no visible leaks. I'm getting a borescope to peak into the bell housing to see if I'm getting leaks there.

I'm running out of ideas. Called McLeod and they gave out some suggestions, which I tried without success.

Any helps/ideas from the forum would be greatly appreciated.

Thanks.
