Wilwood Dynapro 6 Big Brake Front Brake Kit (Hub) - Manual (Page 5)

Page 5
Assembly Instructions (Continued)
•Pack the small outer bearing cone (15) with high temperature disc brake bearing grease and
install into front of hub (8). Slide the hub/rotor assembly (8 and 12) with outer bearing cone (15)
onto the spindle. Secure using spindle washer (16), stock adjusting nut and nut locking device.
Adjust bearings per Original Equipment Manufacturer (OEM) specifications.
•Install the dust cap (17) onto the hub (8). Friction created by the o-ring (18) on the dust cap
(17) keeps it from unscrewing. The O.D. of the existing spindle washer may be larger than
the I.D. of the dust cap (17) not allowing it to seat against the hub face. Some grinding on
the washer O.D. may be necessary to clear the I.D. of the dust cap (17).
•NOTE: Please reference the caution statement at the beginning of the assembly instructions.
This kit contains distinct right and left hand calipers that must be mounted in a specific direction,
as described below. Mount the caliper (19) onto the caliper bracket (1) using bolts (21) and
washers (20), as shown in Figure 1. Initially place two .032” thick shims (22) on each bolt
between the caliper and the bracket. 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 mounting bolts and view the rotor (12) through the top opening of the caliper. The
rotor should be centered in the caliper. If not, adjust by adding or substracting shims (22)
between the bracket and the caliper. Always use the same amount of shims on each of the two
mounting bolts. NOTE: The end of the bolt must be flush with or slightly protuding from the
head of the clinch nut in the bracket. If necessary, place spare shims between the washer
and the caliper mounting ear to achieve the proper clinch nut engagement, as shown in
Figure 4. Once the caliper alignment and clinch nut engagement are correct, remove the bolts
one at a time, apply red Loctite® 271 to the threads, and torque to 40 ft-lb.
•Install the disc brake pads (23) and secure using cotter pin (24). Repeat procedure for the
other wheel.
•Temporarily install wheel and torque lug nuts to manufacturer’s specification. Ensure that the
wheel rotates freely without any interference. NOTE: Wheel spacer (Wilwood P/N 300-11961)
MUST be used if any wheel contact surfaces overhang the outside diameter of the hub face.
See warning on page 3.
•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 220-7056,
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 6 for proper bleeding instructions.
• Install the wheel and torque to manufacturer’s specifications. NOTE: Wheel spacer (Wilwood P/N 300-11961) MUST be used if any
wheel contact surfaces overhang the outside diameter of the hub face. See warning on page 3.
