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 work:
Open housing cover (1).
Disconnect plug connection for pulse generator.
Unclip line from holders (2).
Installation note: Ensure proper locking of plug connector and proper seating of rubber grommets.
Disengage line from brake pad wear sensor from holders (1).
Pull brake pad wear sensor (2) in direction of arrow out of brake pad.
Installation note: Make sure brake pad wear sensor (2) is correctly seated in brake pad and holder (1).
