Notes On Handling, Transport And Storage Of Composite Brake Discs - AH42.10-P-9406-12LF
Model All (4xWD, CAR)
Structure
2-piece, internally ventilated, compound brake disk without fasteners, consisting of friction surface (1) and sheet steel bowl (2).
Corrosion protection
- The steel metal casing (2) is galvanized with a zinc nickel coating.
- The gearing area is painted with zinc dust paint.
- The composite brake disk is also painted with zinc dust paint (exception: hub contact surface).
Structure
3-piece, internally ventilated, drilled compound brake disk with cast-iron friction surface (1) and aluminum bowl (3).
Structure
2-piece, internally ventilated, drilled compound brake disk with cast-iron friction surface (1), steel bowl (2) and wear bores.

Handling the composite brake disk
- For wheel combination components (wheel, compound brake disk, wheel hub), it must be ensured that the vehicle-specific rated torque is first reached in step 3.
- The composite brake disk must be corrosion free (dry storage etc.).
- Damage to the paint and coating of the composite brake disk is not permitted.
- Prevent brake disk from coming into contact with aggressive media (e.g. acids) (exception: Wheel cleaners approved by Mercedes-Benz).
- The steel metal casing base (wheel and hub contact surface) as well as the corresponding contact components (wheel and hub) must be free of soiling and corrosion before assembly.
- Do not apply axial forces on sheet steel bowl (2) or aluminum bowl (3) and circumference of brake disk.
- Do not apply lateral forces (parallel to rotational axis) (e.g. fastening through safety screw only).
- The composite brake disk may only be handled on the friction surface (1) and not on the sheet steel bowl (2) or on the aluminum bowl (3).
- Do not use compound brake disks anymore after a shock, impact or after being dropped.
- Do not separate sheet steel bowl (2) or aluminum bowl (3) from friction surface (1).
While carrying out the following operations, be careful with the compound brake disks so as to avoid damage to the friction surface (1):
- When detaching/attaching wheel and tire assemblies.
- During removal/installation of brake calipers, brake linings and brake disks.
- While working in the area of the wheel arches, e.g. removing/installing suspension struts, transverse control arms, stabilizer bars etc.
- While lowering vehicle with removed wheel and tire assemblies.
Avoid any metallic impacts (risk of damaging corrosion protection)
Avoid any shocks, impacts to the friction surface (1) (e.g. on mount carrier) or use installed disk as padding/supporting surface (e.g. for steering knuckle)
Only turn the steering by turning the steering wheel, not by pulling or pushing on the brake caliper and compound brake disk.
Otherwise, the compound brake disk may become damaged.
Avoid steering knuckle turning against steering resistance through composite brake disk pressure
