Removing Front Brake Disc

→ Use two assembly pins when removing and fitting the wheel.

→ Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.

1. Screw the two assembly aids (assembly pins) -1-  , instead of two wheel bolts, into the wheel hub before removing/fitting the wheel. During removal, first remove the three remaining wheel bolts and remove the wheel carefully without touching the brake discs.
