or subtracting shims between the bracket and the caliper. Always use the same amount of
shims on each of the two mounting bolts. NOTE: The end of each bolt must be flush with or
slightly protruding from the head of the clinch nut, as shown in Figure 4.
If necessary place
spare shims between washer (22) and 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 bolt threads, and torque to
40 ft-lb.

•Install the disc brake pads (25) into the caliper, with the friction material facing the rotor (14),

and secure in place using the pad clip retainer (26), Photo 11.

•Temporarily install wheel and torque lug nuts to manufacturer’s specification. Ensure that the

wheel rotates freely without any interference. NOTE: Wheel spacer (27) MUST be used if any
wheel contact surfaces overhang the outside diameter of the hub face. See warning on page 4.

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 hoses to prevent contact with moving
suspension, brake or wheel components. NOTE:
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

universal brake flex line hose kits, order P/N 220-7056 for the 14 inch length, P/N 220-7699 for
the 16 inch length, or P/N 220-8307 for the 18 inch length. Hose kits include hoses, fitting, 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, referring to the additional information and recommendations on page 7 for proper bleeding instructions. Check

system for leaks after bleeding.

• Install the wheel and torque to manufacturer’s specifications. NOTE: Wheel spacer (27) MUST be used if any wheel contact surfaces

overhang the outside diameter of the hub face. See warning on page 4.
