CAUTION: Never turn the adjuster (23) without the
shear adapter (61) installed. The shear adapter is a
safety feature and is designed to prevent excessive
torque from being applied to the adjuster. The shear
adapter will fail (by breaking) if too much torque is
applied.

Note: Always double-check that the spring brake is released
(where applicable) if a shear adapter fails; if this step was
missed, the shear adapter will break off, and it may appear
that the caliper is seized.
