WARNING: This page is about a different car, the 2011 BMW X6 and 2010 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: The brake pad wear sensor must be replaced once it has been removed (brake pad wear sensor loses its retention capability in the brake pad).

Necessary preliminary tasks:

Remove WHEEL

Read and comply with GENERAL INFORMATION .

After completing work, bleed braking system. See BLEEDING BRAKE SYSTEM WITH DSC or REPLACING FLUID IN ABS/ASC+T BRAKE SYSTEM .

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.
