TECHNICAL INFORMATION
If the front brake pads and the rear brake pads are exchanged together, the parking brake button must be operated 1x and released again after completion of the first exchange (e.g. front brake pads).
If not observed, a fault memory entry will take place.

TECHNICAL INFORMATION
Before first working on the DSCi brake (integrated brake), the "DSCi" web-based training must be passed successfully.
The "DSCi" web-based training is started in the Learning Management System (TMSi).

TECHNICAL INFORMATION
After a brake pad exchange and before pressing the brake pedal: It is imperative to apply the electromechanical parking brake.
If this is not observed, a CC message appears and the brake system switches to the emergency program. The brake booster is no longer active.

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. 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!

TECHNICAL INFORMATION
When pressing the brake piston back, note the brake fluid level in the expansion tank.
Overflowing brake fluid will damage the paintwork.

- Press the brake piston on the brake pads (1) with the special tool 2 352 960 .
- Push the brake pistons alternately up and down to the stop.
- Release nuts (1).
- Remove the brake caliper (1) in arrow direction.
- Remove brake pad from the brake caliper.
- Tie up the brake caliper (1) with the special tool 2 413 317
.
Do not hang the brake caliper from the brake hose.
Precondition
