Sorry. I have to fix air gap issue. . if air gap is bigger than 0,5 mm it can be adjusted.
And B can not be under 1.6 mm.

"1 Check if:
a) There is excessive noise from the brake calipers.
b) The air gap (8) is within the permissible range: A ≤ 0.5 mm.
2 If air gap A > 0.5 mm, adjust the air gap as instructed in section “Adjustment of
Air Gap and Check of Microswitch”.
Prior to adjusting, consider that the distance B between the head of the
adjustment screw and the counternut could become too small.
If B < 1.6 mm, the entire brake caliper has to be replaced."
