34 35 001 Replacing a brake pad sensor (rear)
WARNING: This page is about a different car, the 2016 BMW Z4, 2015 BMW Z4, and 2014 BMW Z4. 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 an already ground brake pad wear sensor has to be replaced although the MINIMUM BRAKE PAD THICKNESS has not yet been reached, it is necessary to file down the new sliding contact with a file to the same length as the ground sliding contact.
