34 35 001 Replacing a brake pad sensor (rear)

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.

Necessary preliminary tasks:

Remove WHEEL at the rear right.

Open housing cover.

Disconnect plug connection (1).
