I have the Motive Products Power Bleeder. It is really good for flushing brake fluid and for bleeding brakes after work has been done at one of the wheels (replacing brake lines, for example). It does not seem to be very good at bleeding entire systems. I replaced the master cylinder and most of the steel brake lines on an old pickup that I have, so I had air throughout the whole system. I have tried several times to bleed the system with the Motive bleeder, but the brakes are still soft. The bleeder doesn't seem to push the fluid through with enough velocity to carry the air past the high points in the system.

The other problem I had with the bleeder is that the tubing doesn't seem to resist brake fluid very well. I had the thing hooked up to the car with the pressure pumped up when the line blew out, sending brake fluid everywhere in a nice fine mist. I was thinking of replacing the clear vinyl tubing that came with the bleeder with rubber fuel line hose.
