Tappet and Boot Assembly (13) Removal
CAUTION: NEVER EXTEND THE TAPPET MORE THAN
1.75 in. (44.5 mm). See Figure 47. Over-extending the
tappet will result in the tappet losing engagement with
the threads of the synchronizing mechanism. Since
the mechanism can only be set at the manufacturing
plant, the caliper/carrier assembly must be replaced
if this happens.

Important: If the vehicle is equipped with spring brakes,
cage the spring brakes on all axles requiring work.
Consult the vehicle manufacturer’s instructions as
necessary. This procedure may be carried out with
the air disc brake installed on, or removed from, the
vehicle. In cases where the caliper/carrier assembly
is removed from the vehicle, NEW fasteners must be
used and properly torqued during re-installation. Use
only fasteners approved by the vehicle manufacturer.
Note: This maintenance procedure uses specialized
tools. 7KHIXOO%HQGL[DLUGLVFEUDNHWRRONLW.
