34 35 513 Replacing A Brake Pad Sensor (Rear)

WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. 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).
If a brake pad sensor that has already been ground has to be replaced even though the MINIMUM BRAKE PAD THICKNESS has not yet been reached, you must observe the following: The new sliding contact must be filed down with a file to the same length as the ground sliding contact.

Necessary preliminary tasks: 

Release fastening elements (1 to 3).

Swing wheel arch panel (4) upwards.

Installation note: 

If necessary, replace defective retaining elements.
