1. A brake crawler assembly configured for vertically moving an arm assembly along a pivot member in a multi-disk hard disk drive, comprising:
a first clamp including:
a first recess within which is disposed a first actuator;
a first clamp calibration element including:
a first clamp calibration access portion adapted to be accessible externally of the first clamp and adapted to receive a first external adjustment; and
a first clamp internal compression modifier adapted to modify a force exerted by the first actuator on the first recess, responsive to the received first external adjustment,
wherein the first clamp is configured to selectively engage the pivot member at a position along the pivot member relative to at least one disk of the multi-disk hard disk drive based on the modified force exerted.
