34 35 003 Replacing a brake pad sensor (rear)

WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2008 BMW 335xi, 2008 BMW 335i, 2008 BMW 328xi, 2008 BMW 328i, and 2008 BMW 323i. 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 wear 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:

Remove Wheel

Slacken nut (1). Pull wheel arch trim (2) gently to one side. Disengage cable from holders (3).
