Grump, That makes alot of sense. I used a clear line on the bleeder valve so I could moniter the brake fluid being pushed out. In the arc of the clear line there was always a little air pocket. So I tryed putting the catch can and bleeder line as low as possible, but still couldn't get that little air pocket out of the line. I still think the piston in the master cylinder is part of my problem, but will try your theory.
Thanks, Kerby
