4.11 Adjustment of brake torque
The clamping force between the linings and the
disc and so the brake torque is created by a
helical compression spring.
The adjustment of the brake torque is done by
increasing or decreasing the spring preload
with the help of the adjustable spring chamber
(see figure 10 and figure 11).
Ex works the clamping force is already adjusted
to the brake torque the customer has specified
in his order. If there is no specification the
brake is adjusted to the minimum clamping
force. In this case the brake torque has to be
adjusted at site.
The adjustment of the brake torque is carried out as follows.

Ascertain the required dimension x for the overhang of the adjustable spring chamber out of the
housing acc. to figure 11.

Turn around the spring chamber (figure 10 and figure 11) with a hexagon key Ø5 mm till the
ascertained overhang is reached.
