• Installation of this kit should ONLY be performed by persons experienced in the installation and proper operation of disc brake systems.
Before assembling this Wilwood front disc brake kit, double check the following to ensure a trouble free installation.
•Make sure this is the correct kit to fit the exact make and model year. This kit is specifically designed as a direct bolt-on OE replacement
for 2007 through 2011 model year Ford Mustang GT500.
•Verify the hat lug pattern in this kit matches the lug pattern of the vehicle’s axle hub.
•Inspect the package contents against the parts list to ensure that all components are included.
Disassembly Instructions
•Disassemble the original equipment front brakes:
Raise the front wheels off the ground and support the suspension according to the vehicle manufacturer’s instructions.
Remove the wheel, caliper, and rotor.
Remove all nicks or burrs on the hub/axle flange face or registration diameter that may interfere with the installation of the new
hat/rotor.
Clean and de-grease the axle hub.
Assembly Instructions (numbers in parenthesis refer to the parts list and Figure 1 on the preceding page):
• Orient the rotor (1) and the hat (2) as shown in Figure 1. Attach rotor to hat using bolts (3)
and washers (4). Using an alternating sequence, apply red Loctite
®
271 to the threads, and
torque to 155 in-lbs. 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 2. 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 hat/rotor assembly onto the axle hub. NOTE: The hat must fit flush against the
axle hub flange or excessive rotor run out may result. Install three lug nuts (finger tight) to
keep the hat/rotor assembly in place while continuing with the installation.
•Remove the OE pads from the caliper and insert the Wilwood brake pads (5) into the caliper,
with the friction material facing the rotor.
•Reinstall the caliper in its original location and torque the mounting bolts to manufacturer’s
specification.
