Wilwood Forged Dynalite Front Drag Brake Kit - Manual (Page 3)

General Information and Disassembly Instructions
General Information:
Installation of this kit should ONLY be performed by persons experienced in the installation and proper operation of disc brake systems.
Before assembling the Wilwood front disc brake kit, double check the following items to ensure a trouble-free installation. Also, please read
these instructions thoroughly to be sure you have a complete understanding of the procedure involved before work is begun.
•Make sure this is the correct kit to match the exact make and model year of the vehicles spindle (i.e., hubs for a 1960 Ford spindle will
not fit a 1969 Ford spindle). On some models of disc brake spindles there are “ears” where the OEM calipers were mounted and these
“ears” interfere with the assembly of the Wilwood disc brake kit. If it becomes necessary to remove these “ears”, remove as little as
possible being careful not to cut away any of the mounting holes that may be required to bolt on the caliper mounting bracket.
•Verify the hub stud pattern in this kit matches the stud pattern of the vehicles wheels.
•Inspect the package contents against the parts list (below) to ensure that all components and hardware are included.
•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 (Wilwood P/N 300-11961, sold separately) 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, sold separately) 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 center cap, cotter pin, nut lock and the wheel bearing nut and washer. Save the wheel bearing nut and nut lock.
Remove the brake drum and hub assembly, including the wheel bearings. Disconnect the brake hoses from the brake line at the
body. Remove the two upper backing plate retaining nuts and bolts. Remove the two lower ball joint to spindle nuts and bolts. The
backing plate, spindle and ball joint will now separate. Remove the brake backing plate and shoes as an assembly. Reinstall the
front ball joint bolt and nut. Do not tighten at this time. Do not reinstall the rear bolt and nut.
Important Notice - Read This First
Before any tear-down or disassembly begins, review the following information:
• Review the wheel clearance diagram (Figure 3, page 5) to verify that there is adequate clearance with the
wheels you will be using with the installation. This kit will result in the wheels being moved out approximately
.50” beyond the stock location.
• Front brake kits do not include flex lines. OEM brake lines will not adapt to Wilwood calipers. Check the
assembly instructions, or associated components section for brake line recommendations before assembly.
In addition, Wilwood offers an extensive listing of brake lines and fittings on our web site:
www.wilwood.com .
• Due to OEM production differences and other variations from vehicle to vehicle, the fastener hardware and
other components in this kit may not be suitable for a specific application or vehicle.
• It is the responsibility of the purchaser and installer of this kit to verify suitability / fitment of all components
and ensure all fasteners and hardware achieve complete and proper engagement. Improper or inadequate
engagement can lead to component failure.
