Wilwood Forged Dynalite Big Brake Front Brake Kit (Hub) - Manual (Page 4)

•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, wheel bearing nut and wheel bearing washer. Save the wheel bearing nut and nut
locking device. Remove the brake drum or rotor and hub assembly, including the wheel bearings. Disconnect the brake hoses
from the brake line at the body. Unbolt and remove the original caliper and caliper bracket. Remove the dust shield retaining bolts
and the dust shield.
•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 (1) should be installed first with clean, dry threads on the
mounting bolts. Position the caliper mounting bracket (1) on the inboard side of the spindle.
NOTE: Be sure the heads of the caliper bracket (1) insert nuts are facing outward toward the
wheel. Slide bolt (2) through washer (3) and through the upper section of the spindle into the
caliper mounting bracket (1). Slide bolt (4) from the backside through washer (3) and into the
mounting boss on the spindle body (reference figure 1). Finger tighten only at this time. The
bracket must tighten squarely against the inboard side of the spindle body. Inspect for
interference from casting irregularities, machining ridges, burrs, etc. Later, after the caliper,
pad, and rotor alignment has been checked, and any necessary shims have been put in place,
the threads of the mounting bolts should be coated with red Loctite® 271 (see below).
•Install wheel studs (5) into the hub (6). Torque to 77 ft-lb. NOTE: There are two lug patterns
of five holes each in the hub (5 x 4.50 and 5 x 4.75). Make sure of the correct hole pattern
for the wheel application before installing the studs into the hub.
•Orient the rotor (10) and the rotor adapter (9) as shown in Figure 1. Attach the rotor to the
adapter using bolts (11). Using an alternating sequence, apply red Loctite® 271 to the threads,
and torque to 25 ft-lb.
•Mount the adapter/rotor assembly (9/10) to the hub (6) using bolts (12), as shown in Figure 1.
Using an alternating sequence, apply red Loctite® 271 to the threads, and torque to 55 ft-lb.
•Pack the large inner bearing cone (7) with high temperature disc brake bearing grease
(available from your local auto parts store) and install into the backside of the hub (6).
•Install the grease seal (8) by pressing into the backside of the hub (6).
•Pack the small outer bearing cone (13) with high temperature disc brake bearing grease and
install into front of hub (6). Slide the hub assembly (5, 6, 7, 8, 9 and 10) with outer bearing
cone (13) onto the spindle. Secure using spindle washer (14), stock adjusting nut and nut
locking device. Adjust bearings per Original Equipment Manufacturer (OEM) specifications.
