Tim its no good.. I beleive the factory systems were "sealed systems". Theres a chance im wrong, but if you dont see a bleeder screw, its no good. The after market versions are usually the ones that can be bled.
I ran into the same problem and had to machine a small AN fitting down to accept the hydraulic TO bearing and seat in the master. Alot of measurement with a caliper and a dowel to get the #'s right. Also need to determine where the roll pin goes when they chuck up the fitting in a lathe to turn it down. There was a company selling them and I can't for the life of me find the link. Edit- I thought you were using an aftermarket TO bearing...that's when I had to make the fitting. I was using a McLeod TO to a parts store master. Try the Third Gen message boards and see what those guys are doing.
