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

Assembly Instructions (Continued)
•Mount the radial mount caliper bracket (24) to the first “flat”caliper mounting bracket (1) from
the far side by sliding bolt (22) through washer (23). Place two .030 thick flat washers (26)
between the two brackets (1 and 24) before sliding the mounting bolts (22) all the way into the
first caliper mounting bracket (1). Finger tight only.
•NOTE: This kit contains distinct right and left hand calipers that must be mounted in a specific
direction, as described below. Lubricate caliper mounting studs (29) and nuts (27) with
lightweight oil. Install spacer (30) and one shim (31) over each stud (29) on the radial mount
bracket (24). Slide the caliper (21) in place over the studs and rotors and install the washer (28)
and lock nut (27) to hold the caliper in place, Figure 1. Ensure that the caliper is mounted so that
the largest pistons are at the rotor exit end of the caliper, in relation to the direction of rotor rotation.
Snug the lock nuts (27) and check that the rotor (12) is centered in the caliper (21). Add or
subtract .030" shims (26), or add additional .015” shims (25), as necessary between the radial
mount bracket (24) and the flat bracket (1) to center the caliper. Finger tighten and recheck
alignment. Use as many shim washers (combination of 25 and 26) as necessary to achieve the
correct alignment. Apply red Loctite® 271 to bolt threads (22) and torque to 42 ft-lb.
•Remove the caliper center bridge pad retainer bolt, nut, and tube from the caliper. Slide the brake pads (6) into place. They should
install easily without interference. Check that the outside radius of the brake pad is aligned with the outside diameter radius of the rotor
face. Add or subtract shims (31) between the caliper (21) and radial mount bracket (24) to gain the proper alignment. Reinstall the
caliper and torque the caliper nuts (27) to 28 ft-lb. Reinstall 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.
•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.
•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.
•Repeat assembly procedure for the other wheel.
•Bleed the brake system. Reference the general information and recommendations on page 6 for proper bleeding instructions.
•Please read the following concerning balancing the brake bias on 4 wheel disc vehicles.
This General Motors spindle kit can be operated using the stock OEM disc brake master cylinder. However, as with most
suspension, brake and/or tire modifications (from OEM specifications), changing the brakes may alter the front to rear brake bias.
Rear brakes should not lock up before the front. Brake system evaluation and tests should be performed by persons experienced
in the installation and proper operation of brake systems. Evaluation and tests should be performed under controlled conditions.
Start by making several stops from low speeds then gradually work up to higher speeds. Always utilize safety restraint systems
while operating vehicle.
For competition or modified vehicles, please see biasing instructions on page 6.

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
