......Oh yeah......If you disconnect the power bleeder from the system wrong, I think you will force air into the lines. As the directions should state, if there is any fluid left in the bottom of the bleeder after bleeding, tilt the bottle to the side and unscrew the
bottle cap, not the MC connection, to release pressure. Then you are safe to unscrew it from the MC. This is just my re-collection of the directions, its been a few years since I last used my Motive unit. Could be completely off base.
I'm sure you know to start at the farthest wheel away from the MC and work your way to the closest (gotta ask, since it's your first bleeding
).
