8. Brake and Wheel Installation
Caliper Installation
Reinstall and adjust the brake
pads and brake caliper according
to the brake manufacturer’s
recommended instructions.
Wheel Installation
1. Reinstall the wheels and torque
the wheel bolts in a star pattern
to 450-500 ft-lbs. The last nut
rotation must be with a torque-
controlled device.
2. After the rst 50 to 100 miles,
retorque the wheel nuts to 450-
500 ft-lbs in a star pattern. The
last nut rotation must be with a
torque-controlled device.
Hub Pilot Wheel Mounting
System
The brake drum must be fully seated on the drum
pilot and against the hub face during and after
installation of the wheel(s).
CAUTION
!
If your shop practice requires the use of lubricant
or anticorrosion material to the threads and/or the
drum pilot area, avoid getting lubricant on the at
mating surfaces of the hub, drum, and wheels.
NOTE
Always snug the top nut rst to fully seat the
brake drum on the drum pilot and against the hub
face. See the adjacent diagram for bolt tightening
sequence, and tighten in order from 1 through 8
or 10, depending on the bolt pattern (see gure
89 and gure 90).

1. Clean all mating surfaces
on the hub, drum and nuts.
Remove loose paint, scale, and
any material building around
the pilots of the drum, hub, and
wheels. Be sure paint is fully
cured on recently refurbished
wheels.
Care should be taken to avoid damaging the hub
or other components.
CAUTION
!
If you plan to replace the brake drum (i.e., cast in
place of CentriFuse®) or wheels (i.e., aluminum
in place of steel), measure stud standout (see
gure 91). In hub piloted mounting systems, the
studs must be long enough for the threads to
be exposed beyond the installed wheel nut. In
the ball seat mounting system, the stud length
beyond the brake drum should be from 1.31-1.44"
as measured from the brake drum to the end of
the stud. Call ConMet at 1-800-547-9473 for the
correct stud part number for your application.
If you plan to replace the brake drum, verify the
new drum has the same drum pilot diameter as
the one that has been removed.

2. In environments where a
corrosion inhibitor is benecial,
ConMet recommends the use
of Corrosion Block, a product of
Lear Chemical Research, (905)
564-0018. In severely corrosive
environments, a light coat of
Corrosion Block on the drum
and wheel pilots has proven
benecial.
3. In addition to the above
preparation, apply two drops of
oil to a point between the nuts
and nut ange washer and two
drops to the last two or three
threads at the end of each
stud. Also, lightly lubricate the
pilots on the hub to ease wheel
installation and removal.
