A) Externally setting the brake torque:
•
To increase or decrease the desired brake torque
, proceed as follows:
1. Loosen the “hexagonal concave head” centre screw (fig. 17);
•
to increase the brake torque:
remove one or more washers until obtaining the desired brake torque
(fig. 18);
•
to decrease the brake torque:
with all washers
inserted under the “hexagonal concave head” screw,
the spring thrust is at its minimum setting, and consequently the brake torque is also at a minimum.
2. Reset the “hexagonal concave head” centre screw (with the desired washers) and tighten securely (fig.
19);
3. Perform driving and braking tests, and if necessary repeat the above steps until obtaining the desired
brake torque, after having reassembled the aerator and securely tightened the “hexagonal concave head”
screws (fig. 20).

If the brake torque adjustment has been performed several times and the desired braking
space is not achieved, proceed as outlined under the following point B) “Internally restoring
the brake play.”
