2. Position the open brake on the brake
holding rail so that there is 3 mm clearance
between the brake bolt and tyre up to a
maximum of 4 mm.

from 3 mm to maximum 4 mm, with opened brake
3. Tighten the M5 fixing screws (AF 4 mm)
again to 4 Nm.
4. Then check the correct setting of the
brakes: When the brake is closed,the
braking bolt presses the tyre in by approx.
4 mm. When the brake is not applied, the
brake bolt may not drag along the tyre.
5. The actuating force of the brake lever can
be adjusted via the M5 joint screws. For
this purpose, you need a slotted
screwdriver and an open-ended spanner
(AF 8 mm). The screw is retained at the
front with the slotted screwdriver and the
open-ended spanner (AF 8 mm) is used to
either screw tight or to loosen a little. An
important point here is that both joint
screws must be tightened equally as this
leads to a long-lasting uniform actuating
force of the brake lever.

force of the brake lever
Generally, the braking bolt is mounted in
the standard position (see following figure).
The assembly of the braking bolt in the other
possible position (see following figure) may be
necessary after the adjustment of the drive
wheels.
