Wilwood Dynapro Dust-Boot Pro Series Front Brake Kit - Manual (Page 4)

General Information (Continued), Disassembly and Assembly Instructions
•WARNING: The wheel contact surfaces must
seat completely on the face of the hub. If any
contact surfaces overhang the outside diameter
of the hub face, a 6.60” diameter x .20” thick
steel spacer (item 27, Wilwood P/N 300-11961)
MUST be used between the wheel and the hub.
•To prevent damage to the hub face, a 6.15”
diameter x .09” thick hub shield (Wilwood P/N
300-10716) should be used with any stamped
steel wheels that do NOT overhang the outside
diameter of the hub face.
•Always tighten lug nuts to the wheel
manufacturer’s specifications.
•Always recheck the lug nuts after test driving the vehicle at safe speeds. If they are
NOT still tight, inspect the wheel-to-hub contact surfaces for damage and/or
incomplete contact.
•As routine maintenance, periodically remove the wheels and inspect the wheel-to-
hub contact surfaces for damage.
•It is the installer’s responsibility to ensure that the wheels used with this hub kit are
properly and securely installed. Some wheels may NOT be compatible with the hub
in this kit.
Disassembly Instructions:
•Disassemble the original equipment front brakes:
Raise the front wheels off the ground and support the front
suspension according to the vehicle manufacturer’s
instructions.
Remove the front wheels and completely disassemble the
stock brake system down to the bare spindles. Save the
Original Equipment Manufacturer’s (OEM) spindle nuts, nut
locks (if any), and the forward steering arm bolts and nuts.
•Remove any nicks or burrs on the spindle mount faces that may
interfere with the installation of the new brake components.
•Clean and de-grease the spindles and saved components.
Assembly Instructions (numbers in parenthesis refer to the
parts list and Figure 1 on the preceding page): CAUTION: All
mounting bolts must fully engage clinch nuts. Be sure to check
that all bolts are either flush or protruding through flanged side of
clinch nut after shimming, Figure 4.
•NOTE: 1964-66 spindles may require the following modifications
(reference Figure 1 and Figure 3): Top anchor pin hole (Z) must
be drilled and tapped to the dimensions as outlined in Figure 3.
Bottom rear steering arm bolt hole (Y) in the spindle and steering
arm must be enlarged to .50” by drilling.
