configuration. Always use the same amount of shims on both the top and bottom caliper
mounting bolts (14). Apply red Loctite® 271 to bolt threads (14) and torque to 40 ft-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.
•Install the disc brake pads (16) and secure using retainer clip (17).
•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.
•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.
