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

•With the larger I.D. side of the rotor (5) facing away from the hat (6), bolt rotor (5) to hat (6)
through the backside of the rotor using washers (7) and bolts (8). 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 3. Please refer to Wilwood’s data sheet DS-386 (available
at
www.wilwood.com/Pdf/DataSheets/ds386.pdf ) for complete safety wire installation
instructions. Slide the rotor/hat assembly onto the hub. Install a couple of lug nuts (finger
tighten) to keep the rotor/hat assembly in place while continuing with the installation.
•NOTE: Please reference the caution statement at the beginning of the assembly instructions.
Mount the caliper (9) onto the caliper mounting bracket (1) using bolts (10) and washers (11).
Insert spacer between the caliper ears and the bracket before tightening the bolts. View the rotor
(5) through the top of the caliper. The rotor should be aligned in the center of the caliper. If
not, loosen the two bolts and adjust the caliper by using 0.016 inch thick shims (12), placed
between the spacer (13) and the bracket, Figure 1. Finger tighten and recheck alignment.
Always use the same amount of shims on both the top and bottom caliper mounting bolts.
Loosen the two bolts and apply red Loctite® 271 to bolt threads and torque to 60 ft-lb.
•Remove the caliper bridge bolt and install the disc brake pads (14) then reinstall the caliper
bridge bolt. Repeat this procedure for the other wheel.
•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 220-8336,
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.
•Remove the two lug nuts that were used to hold the rotor/hat assembly in place during caliper installation. Install the wheel and lug
nuts, torque to OEM specifications.
•Repeat this entire procedure for the other wheel.

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
