mickmate, that method works well, IF, the threads around the bleeder valve aren't letting air back in the system and there is an air tight seal on the tube over the tip of the bleeder valve. Sometimes it's tough to get both to work.

Jim, purging is a CLASSIC case of when I pull the bleeder valve out and use the finger method. You can get a LOT of fluid out with every stroke of the brake pedal. When you see the fluid color start to clear up or change, then switch back to the bleeder valve method. I recently bled both the ERA and my auto trailer using the finger method to purge the system of old fluid. Worked well, I was done in no time. Of course it is a two man job, that can be a serious downside sometimes.
