Wilwood Dynapro Radial Big Brake Front Brake Kit (Hat) - Manual (Page 3)

General Information, Disassembly, and Assembly Instructions
Parts List
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 spindle (i.e., brackets for a 1998 Golf may not fit a 2003 Golf 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. Remove the two bolts that hold the stock caliper mounting
bracket to the spindle. 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 spindles.
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.
•The caliper mounting bracket assembly (1) should be installed first with clean, dry threads on the mounting bolts. Install the bracket
from the rear side of the spindle by sliding bolts (2) through washer (4). Place spacer (5), and washer (6) between the bracket (1) and
the backside of the spindle (see Figure 1). The bracket must tighten squarely against the side of the spindle body. Inspect for
interference from casting irregularities, machining ridges, burrs, etc. Use one thin shim (6) between the spacer and spindle during
initial trial fitting.
