Wilwood Forged Dynalite Big Brake Front Brake Kit (Hat) - Manual (Page 4)

Assembly Instructions (numbers in parenthesis refer to the parts list and Figure 1 on the preceding pages): CAUTION: All mounting
bolts must fully engage clinch nuts. Be sure to check that all bolts are either flush or protruding through flanged side of clinch nut after
shimming, Figure 3.
• Orient the caliper mount bracket (1) as shown in Figure 1 and
Photo 1, and install using bolts (2) and washers (3). Place a
spacer (4) on each bolt between the bracket and caliper
mounting bosses, Figure 1 and Photo 2. Ensure that the flanged
heads of the clinch nuts in the bracket are facing outboard,
Photo 1. Temporarily tighten the mounting bolts. NOTE: The
bracket must fit squarely against the mount bosses on the
upright.
Inspect for interference from casting irregularities,
machining ridges, burrs, etc. Remove bolts one at a time, apply
red Loctite
® 271 to the threads and torque to 30 ft-lb.
• Orient the rotor (6) and the hat (7) as shown in Figure 1 and
Photo 3. Attach rotor to hat using bolts (9). Using an alternating
sequence, apply red Loctite
® 271 to the threads, and torque to
25 ft-lbs.
•Slide the rotor registration adapter (5) onto the axle register on
the axle hub with the smaller O.D. facing toward the rotor/hat
(6/7), Photo 4. Slide the hat/rotor assembly onto the axle hub.
NOTE: The hat must fit flush against the axle hub flange or
excessive rotor run out may result. Install three lug nuts (finger
tight) to keep the hat/rotor assembly in place while continuing
with the installation.
•NOTE: Please reference the caution statement at the beginning
of the assembly instructions. This kit contains distinct right and
left hand calipers that must be mounted in a specific direction, as
described below.
Mount the caliper (10) onto the caliper
mounting bracket (1) using bolts (12) and washers (11), as
shown in Figure 1. Initially place two .035” thick shim (13) on
each bolt between the caliper and the bracket, Photo 5. Ensure
that the caliper is mounted so the largest pistons are at the rotor
exit end of the caliper, in relation to the direction of rotor rotation.
Temporarily tighten the mounting bolts and view the rotor (6)
through the top opening of the caliper. The rotor should be
centered in the caliper, Photo 6. If not, adjust by adding or
subtracting shims between the bracket and the caliper. Always
use the same amount of shims on each of the two mounting
bolts. NOTE: The end of each bolt must be flush with or slightly
protruding from the head of the clinch nut, as shown in Figure 3.
If necessary place spare shims between washer (11) and caliper
mounting ear to achieve the proper clinch nut engagement.
Once the caliper alignment and clinch nut engagement are
correct, remove the bolts one at a time, apply red Loctite® 271 to
bolt threads, and torque to 40 ft-lb.
•Install the disc brake pads (14) into the caliper, with the friction material facing the rotor (6), and
secure in place using the pad clip retainer (8), Photo 7.
•Temporarily install wheel and torque lug nuts to manufacturer’s specification. Ensure that the wheel
rotates freely without any interference.
