Per the manual the pistons in all three calipers need to be pushed back fully prior to filling the resevoirs in the servo unit. This is important to establish a consistent reference to avoid too much or too little fluid in the sytem... you'll understand once you do it. The shims keep the pistons in during the bleed process. I use window shims... of couse BMW sells the official tool for $$$$.

Servo brakes are loved or hated... I have mixed feelings about them. I have removed the system on a few bikes after the servo failed.
