•Slide the rotor registration adapter (10) onto the axle register on
the axle flange with the smaller O.D. facing toward the rotor/hat
(3), Photo 3. Align the correct hole pattern in the rotor/hat with
the stud pattern on the axle flange and slide into place, Figure 1
and Photo 4. NOTE: The rotor/hat must fit flush against the axle
flange or excessive rotor run out may result. Install three lug nuts
(finger tight) to keep the rotor/hat assembly in place while
continuing with the installation. NOTE: Some OEM and after
market axles come with stud sizes larger than 0.50” diameter.
Verify stud size and have a qualified machine shop drill the bolt
circle of the hat/rotor to the correct stud size, if necessary.
•NOTE: Please reference the caution statement at the beginning
of the assembly instructions. Mount the caliper (4) onto the
caliper mounting bracket (1) using bolts (6) and washers (5), as
shown in Figure 1. Initially place two .035” thick shims (7) on
each bolt between the caliper and the bracket, Photo 5.
Temporarily tighten the mounting bolts and view the rotor (3)
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 5.
If necessary place spare shims between washer (5) 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 (8) into the caliper, with the friction
material facing the rotor (3), and secure in place using the pad
clip retainer (9), Photo 7.
•Temporarily install wheel and torque lug nuts to manufacturer’s
specification. Ensure that the wheel rotates freely without any
interference.
•NOTE: Clevis and cable kits which attach to the parking brake
assembly are not included in the Wilwood parking brake kit.
Wilwood offers a generic style parking brake cable kit, P/N
330-9371 for this application which can be ordered separately
from your local Wilwood dealer or by calling Wilwood customer
service at (805) 388-1188.
•Before final installation of the wheel, install three lug nuts, remove the rubber grommet in the bracket kit assembly (1) and adjust the
parking brake shoes outward (using a drum shoe adjustment tool available at your local auto parts store) while spinning the rotor/hat
(3) until a slight drag is felt against the hat/drum. Replace the rubber grommet when finished.
•NOTE: OEM rubber brake hoses generally cannot be adapted to Wilwood calipers. The caliper inlet fitting is a 1/8-27 NPT. The preferred
method is to use steel adapter fittings at the caliper, either straight, 45 or 90 degree and enough steel braided line to allow for full
suspension travel. Carefully route hoses to prevent contact with moving suspension, brake or wheel components. NOTE:
Wilwood hose kits are designed for use in many different vehicle applications and it is the installer's responsibility to properly route and
ensure adequate clearance and retention for brake hose components. Wilwood offers universal brake flex line hose kits, order P/N 220-
7056 for the 14 inch length, P/N 220-7699 for the 16 inch length, or P/N 220-8307 for the 18 inch length. Hose kits include hoses,
fitting, etc., all in one package for this application.
