TECHNICAL INFORMATION
The brake pad wear sensor must be replaced immediately once it has been removed because the brake pad wear sensor loses retention capacity in its 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 sanded sliding contact.
When replacing the brake pad wear sensor, a CBS reset needs to be carried out.
If a brake pad wear sensor was replaced without replacing the brake pads, the following needs to be paid attention to: Carry out the service function "CBS vehicle data correction" via the diagnostic system and information system.
