Stop!
| The minimum thread depth (see Tab. 1) is required to adjust the brake.
| If the required thread depth is not observed the fixing screws may run into
the thread root when adjusting the brake. As a result, the required
prestressing force will no longer be built up and the brake will no longer be
fixed securely!
