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 lining 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:
Disengage cable guides (2).
Open cover (1) on plug housing.
Disconnect plug connection.
Disengage cable from cable guide (3).

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 a brake lining 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:
Open housing cover (1).
Disconnect plug connection (2).
Installation:
Ensure proper locking of the plug connector and proper seating of the cable in the brackets.
