Application
C - During the movement through C, the design clearance is
measured between the pad and brake disc by the adjuster.
There is a predetermined clearance between the tongue of the
adjustment spring and the slot in the companion sleeve, which
determines the free stroke before the adjustment.
Ce - If excess clearance remains after the mechanism has
moved radially in accordance with the design clearance C, the
adjuster, synchronization shaft, pinions, crown wheels, adjusting
shaft/readjustment shaft and the adjustment screws are turned.
The rotation of the adjustment screws means that a percentage
of the measured excess Ce is removed.
In the adjuster, the turning movement is transferred from the
housing via the adjustment spring, companion sleeve, and
friction spring to hub, which engages with the synchronization
shaft.
