Important: To maintain optimal braking, Bendix
strongly recommends that whenever brake pads
are replaced, the complete axle set be replaced
together. Use only pads which are permitted by the
vehicle manufacturer, axle manufacturer, and/or disc
brake manufacturer. Failure to comply with this may
invalidate the vehicle manufacturer’s warranty.
Before installing the brake pads, use the adjuster to
fully retract the tappets to provide adequate clearance.

(See Section 5.2.)
CAUTION: Never turn the adjuster (23) without the
shear adapter (61) installed. The shear adapter is a
safety feature and is designed to prevent too much
torque being applied. The shear adapter will fail (by
breaking) if too much torque is used.
Note: For wheel-ends with spring brakes, if a shear adapter
fails, always double-check to verify that the spring brake
has been released (or caged). If the spring brake is applied,
release or cage the brake (assure that the air system
pressure is at least 90 PSI) and start the procedure again.

CAUTION! Avoid overloading or damaging the adjuster
shaft. Do not use an open-ended wrench since it may
damage the adjuster shaft.
