Parts List
General Information and Disassembly Instructions
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.
•Make sure this is the correct kit to match the exact make and model
year of the vehicles spindle (i.e., hubs for a 1970 Mustang spindle will not fit a 1987 Mustang 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. See spindle modification instructions below.
•Verify the hub stud pattern in this kit matches the stud pattern of the
vehicles wheels.
•Verify your wheel clearance using Figure 3. •Inspect the package contents against the parts list to ensure that all
components and hardware are included.
Disassembly / Spindle Modifications •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 and hub assembly, including the wheel bearings. Disconnect the brake hoses from the brake line at the body. Remove the two upper spindle retaining nuts and bolts. Remove the lower ball joint to spindle nut and bolt. The backing plate, spindle and ball joint will now separate. Remove the spindle assembly.
•Clean and de-grease the spindles. Remove all nicks or burrs on the spindle snout and threads.
•The following spindle modifications should be performed by a qualified machinist. Refer to Figure 2 as necessary. Only one view of the
steering are/spindle is shown, but the modifications need to be performed on both steering arm/spindles.
•With the spindle positioned in its correct upright position with the snout pointing towards you, measure 2.875 inches from the spindle
centerline to lower OEM caliper mounting ear, mark this point. Remove OEM caliper mounting ear from this mark, be careful not to cut into the dust plate mounting hole and raised boss. Remove all sharp corners and burrs with a file or grinder.
