WARNING: This page is about a different car, the 2010 BMW 550i, 2009 BMW 550i, and 2008 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

Necessary preliminary tasks: 

After completing work: bleed brake system with DSC. 

Press clutch pedal down to floor and secure with pedal support.

NOTE: The pedal support may only be released when the brake lines are reconnected.
This prevents brake fluid from emerging from the expansion tank and air from entering the system when the brake lines are opened.
