Wilwood Forged Superlite 4 Big Brake Front Brake Kit (Hat) - Manual (Page 3)

Installation of this kit should ONLY be performed by persons experienced in the
installation and proper operation of disc brake systems. Before installation begins,
please read the complete procedure thoroughly to familiarize yourself with the
process, and 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
vehicle’s hubs (i.e., brackets for a 2000 Toyota spindle will not fit a 2004 Scion
spindle).
•Verify the hat stud pattern in this kit matches the stud pattern of the vehicle’s hubs.
•Verify your wheel clearance using Figure 2.
•Inspect the package contents against the parts list to ensure that all
components and hardware are included.
Disassembly
•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 wheel. Disconnect the caliper brake hose from the brake line at
the body. Remove the two bolts that hold the stock caliper mounting bracket
to the hub. Lift off the bracket and stock caliper as one unit, then slide off the
stock hat and rotor assembly. On some models you may have to unbolt the
stock caliper from the caliper bracket before removal.
•Thoroughly clean the hubs and remove all nicks or burrs.
Assembly Instructions (numbers in parenthesis refer to the part list/diagram on the preceding page): CAUTION: All mounting bolts must
fully engage insert nuts. Be sure to check that all bolts are either flush or protruding through flanged side of insert nut after shimming.
•Insert one sleeve (2) each into the holes on the top and bottom of the spindle “ears” where the OEM caliper bracket was removed.
Apply red Loctite® 271 to the caliper mounting bracket bolt threads (4) before installation of the caliper mounting bracket (1). Install
the bracket with the flanged heads of the clinch nuts facing outboard, as shown in Figure 1. Slide bolt (4) through washer (3) and
into the previously installed sleeve (2), from the backside of the hub. Finger tighten. Repeat for the lower mounting holes. Torque
bolts to 60 ft-lb.
