TECHNICAL INFORMATION
General information on changing the brake pads:
For vehicles older than 48 months it is recommended to replace the retaining spring or expanding spring.
The brake pad wear sensor must be replaced once it has been removed because the brake pad wear sensor loses its retention capability in the brake pad.
A CBS reset must be done after every brake pad exchange:
A CBS reset in the vehicle is possible in the event of a partially ground down brake pad wear sensor. The CBS display in the Central Information Display (CID) is active.
In the event of a brake pad wear sensor that is not partially ground down, a CBS reset is only possible with the diagnostic system using an appropriate scan tool. No CBS display in the Central Information Display (CID).
If adhesive bonded brake pads are installed, the brake pads must be replaced after releasing the adhesive bond!
