8.7 Braking deceleration setting
The brake adjustment is to be carried out only with one effective brake shoe with the
elevator car loaded with the rated load on a descending run (full down) or with an
empty elevator car on an ascending run (empty up) according to the deceleration
values in the table below.
The braking torque must be set on uniformly on both brake shoes by pre-tensioning
the brake spring depending on the installation.

8.8 Brake readjustment in the event of brake lining wear
With wear on the brake linings, the stroke of the brake shoes increases compared
with the reference state (0.3 mm + 0.1 mm). As of a limit value of 0.6 mm, the
following settings on the brake are to be checked and, if required, corrected:
1. Armature base plate pre-tension: check and, if required, adjustment of the pre-
tension
2. Stroke of the brake shoes: setting to reference value 0.3 mm +0.1 mm to
middle of brake disc
3. Pre-tension of the compression springs: setting of the reference value to a
maximum of 20.5 mm, as well as check of the deceleration

4. Setting for brake test switches
5. Operation position of the brake release lever: setting to 5 - 10° above the
horizontal. For readjustment, the lock nut on the pressure rod must be released
and the rod in the pressure piece adjusted. Subsequently secure the setting by
tightening the lock nut.
