Wilwood Forged Narrow Superlite 6R Big Brake Front Brake Kit (Hub and 1PC Rotor) - Manual (Page 5)

•Pack the small outer bearing cone (15) with high temperature
disc brake bearing grease and install into hub (10). Slide the hub
assembly onto the spindle. Secure using spindle washer (16)
and OEM spindle nut, Photo 3. Adjust bearings per OEM
specifications. Install saved OEM nut lock (if any) and a new
cotter pin (not included).
•Screw dust cap (17) into hub (10), Photo 4. Friction created by
the o-ring (18) on the dust cap keeps it from unscrewing.
NOTE: The O.D. of the existing OEM spindle washer may be
larger than the I.D. of the dust cap not allowing it to seat against
the hub face. Therefore, use the spindle washer (16) supplied
with the kit instead of the OEM washer.
• Slide the hat/rotor (13) onto the hub (10) taking care to align the
small countersunk holes in the hat with the small threaded holes
in the hub. NOTE: The hat must fit flush against the hub face or
excessive rotor run out may result. Install three flat head screws
(14) through the small holes in the hat (13), Photo 4, and torque
to 85 in-lb.
• NOTE: This kit contains distinct right and left hand calipers that
must be mounted in a specific direction, as described below.
Lubricate the caliper mounting studs (22) with lightweight oil.
Initially place one .035” thick shim (23) on each stud between the
caliper and the bracket, as shown in Figure 1 and Photo 5.
Mount the caliper (19) onto the bracket (1) using lock nuts (20)
and washers (21), Figure 1. 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
lock nuts.
•Remove the caliper center bridge pad retainer bolt, nut, and tube
from the caliper. Insert the brake pads (24) into the caliper, with
the friction material facing the rotor, as shown in Photo 6. Check
that the top of the brake pad is flush with the outside diameter of
the rotor, Photo 7. If not, adjust by adding or subtracting shims
(23) between the caliper and the bracket. After the caliper pad
height is set, torque the caliper lock nuts (20) to 30 ft-lb. Secure
the brake pads in place with the center bridge pad retainer tube,
bolt, and locknut. The locknut should be snug without play in the
bolt or tube. Be cautious not to over tighten.
•Temporarily install the wheel and torque lug nuts to manufacturer’s specification. Ensure that the
wheel rotates freely without any interference.
•NOTE: The caliper in this brake kit utilizes a 1/8-27 NPT pipe thread inlet. OEM rubber brake hoses
generally cannot be adapted to Wilwood calipers. 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 and turning radius, lock to lock. 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.
