and retain the mounting hardware for the cable
protection plate. The cable protection plate can
then be set aside while servicing the pads. Note the
position of the sensors in the brake pad channels,
and carefully remove them. In most cases you do
not need to release the cable connector in order to
move the sensors away from the pad installation
work area. Inspect the wear sensors - replace if
damaged or abraded.

the adjuster cap (37) using the tab, taking care not
to move the shear adapter (61). Note: One of two
styles of adjuster cap (stamped metal or plastic
adjuster cap) may be found; use the same style as
a replacement in step 5.2.21.

corrosion and/or damage is present, remove the
adjuster adapter using needle-nose pliers and
replace with the adapter supplied in the kit and

5.2.1 CAUTION: Follow all safe maintenance
practices, including those listed on page two of

Important: If the vehicle is equipped with spring brakes,
cage the spring brakes on all axles to be worked on.
Consult the vehicle manufacturer’s instructions as
necessary.
