Wilwood Superlite 6 Big Brake Front Brake Kit (Hat) - Manual (Page 4)

Preinstall Verification Before installation of modified knuckles on vehicle, preinstall
the caliper spindle mounting brackets (6) to backside of knuckles to be sure bracket
lays flat on mounting surface and clears machined away areas for clearance
verifications. If bracket (6) do not fit properly, more maching maybe necessary. Then
install knuckle back on vehicle in reverse order of disassembly.
Assembly Instructions (numbers in parenthesis refer to the part list/diagram on the
preceding page): CAUTION: All mounting bolts must fully engage insert nuts. Be sure
to check that all bolts are either flush or protruding through flanged side of insert nut
after shimming.
•Mount bracket (6) to the backside of the spindle/hub assembly using bolts (11) and
flat washer (12).
•With the larger I.D. side of the rotor (13) facing away from the hat (14), bolt rotor to
hat using washers (15) and bolts (16). Using an alternating sequence, apply red
Loctite® 271 to the threads and torque bolts to 155 in-lb. For an added measure of
security, the bolts may be safety wired using standard 0.032 inch diameter stainless
steel safety wire as shown in Figure 4. Please refer to Wilwood’s data sheet DS-
386 (available at
www.wilwood.com/Pdf/DataSheets/ds386.pdf ) for complete safety
wire installation instructions.Slip the rotor and hat combination onto the wheel studs
and hold in place with three lugs nuts.
•Apply red Loctite® 271 to bolt threads (2) before mounting caliper to the caliper
mounting bracket (1). NOTE: Be sure the heads of the 7/16-20 bracket (1) insert nuts
are facing outward toward the wheel.
•NOTE: Please reference the caution statement at the beginning of the assembly
instructions. With the bleed screws pointing up, mount the caliper (5) to the caliper
mounting bracket (1) using bolts (2) and washers (3), as shown in Figure 1. Torque
bolts (2) to 60 ft-lb. Mount caliper/bracket combination to the spindle bracket (6)
using bolts (7) and washers (8), while placing a shim (9) and spacer (10) between
the two brackets (1 and 6) as shown in Figure 1. Finger tighten only at this time.
•View the rotor (13) through the top opening of the caliper (5). The rotor should be aligned in
the center of the caliper (5). If not, adjust the caliper (5) by using 0.030 inch thick shims (9) placed
between the caliper mounting bracket (1) and the spindle bracket (6). Finger tighten and recheck
alignment. Apply red Loctite® 271 to bolt threads (7) and torque to 60 ft-lb.
•Remove the bridge bolt from the caliper (5) and install the disc brake pads (4). Reinstall the
caliper bridge bolt.
•Disconnect the OEM brake hoses from the brake line at the body & finish removing the OEM caliper.
•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
and turning radius, lock to lock. Carefully route lines to prevent contact with moving suspension, brake or wheel components.
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 a hose kit, P/N 220-6746, which includes hoses,
fittings, etc., all in one package for this application.
•Specified brake hose kits may not work with all Years, Makes and Models of vehicle that this brake kit is applicable to, due to possible
OEM manufacturing changes during a production vehicle's life. It is the installer's responsibility to ensure that all fittings and hoses are
the correct size and length, to ensure proper sealing and that they will not be subject to crimping, strain and abrasion from vibration or
interference with suspension components, brake rotor or wheel.
•In absence of specific instructions for brake line routing, the installer must use his best professional judgment on correct routing and
retention of lines to ensure safe operation. Test vehicle brake system per the 'minimum test' procedure stated within this document
before driving. After road testing, inspect for leaks and interference. Initially after install and testing, perform frequent checks of the
vehicle brake system and lines before driving, to confirm that there is no undue wear or interference not apparent from the initial test.
Afterwards, perform periodic inspections for function, leaks and wear in a interval relative to the usage of vehicle.
• Bleed the brake system. Reference the general information and recommendations on page 5 for proper bleeding instructions.

BEGIN BY SLIDING THE 0.032"
DIAMETER WIRE THROUGH TWO OF
THE HOLES (LEFT) THAT ARE 180°
APART. TWIST THE WIRE AS
SHOWN (BELOW) USING SAFETY
WIRE PLIERS. NOW SLIDE ONE
WIRE THROUGH TWO OF THE
HOLES (180° APART) AND WRAP THE
OTHER WIRE AROUND THE BOLT.
TWIST THE WIRES TOGETHER TO
FORM A PIGTAIL. SEE DS-386 FOR
