I unplugged mine to bleed the control circuits, not the servos. I did it because the BMW manual told me to, but the instruction seemed sensible given the placement of the bleeders on the servo.
Am I about to learn a trick that saves me messing with said connector next time?
No need to unplug them ?
In fact i use the servo motor to bleed the unit. Turn on ignition, touch brake lever, fluid gets pumped out. Simples.
Life couldn't be easier. Saves all that quaint old fashioned pumping of levers.
