Wilwood Forged Dynalite Pro Series Rear Brake Kit - Manual (Page 4)

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.
•With the slot pointing upward and the mounting ears pointing towards the rear of the vehicle,
install the caliper mounting bracket (1) to the housing flange using the stock Original Equipment
Manufacturer (OEM) bolts and nuts. Stock OEM hex nuts that retain the bracket (1) should be on
the wheel side of the bracket. Apply red Loctite® 271 to the stock OEM bolt threads and torque
to OEM specifications. NOTE: Some brackets act as the bearing retainers, while others help
locate the bearing in the axle housing flange. If the stock bearing plates are still on the axle, the
caliper mounting brackets (1) should be located between the axle housing flange and the
bearing retainer plate. Make sure the heads of the caliper mounting bracket insert nuts are
FACING OUTWARD TOWARDS THE WHEEL.
•Bolt the hat (2) to the rotor (3) using washers (4) and bolts (5). Torque bolts (5) to 180 in-lb.
Safety wire bolts (5) using standard 0.032 inch diameter stainless steel safety wire as shown
in Figure 4. Please refer to Wilwood’s data sheet DS-386 (available at
www.wilwood.com/Pdf/DataSheets/ds386.pdf ) for complete safety wire installation instructions.
•Align the correct hole pattern in the hat (2) with the stud pattern on the axle flange.
NOTE: Some OEM and after market axles come with stud sizes larger than 0.50” diameter.
Verify stud size and have a qualified machine shop drill the hats to the correct size. Slide the
hat/rotor assembly (2 and 3) over the wheel studs and against the axle flange face.
•NOTE: Please reference the caution statement at the beginning of the assembly instructions.
WITH THE BLEED SCREWS POINTING UP, mount the caliper (6) over the rotor (3) and onto
the caliper mounting bracket (1) using washers (7) and mounting bolts (8). View the rotor
through the top opening of the caliper. The rotor should be aligned in the center of the caliper.
If not, adjust the caliper by using 0.032 inch shim washers (9), placing them between the caliper
mounting bracket (1) and the caliper (6). Add as many shim washers (9) as necessary to
achieve the correct alignment. NOTE: The end of the bolt must be flush with or slightly
protuding from the head of the clinch nut. See Figure 5. Place spare shims (9) between
washer and caliper mounting ear to achieve the proper mounting fastener configuration.
Always use the same amount of shims on both the top and bottom caliper mounting bolts (8).
Apply red Loctite® 271 to the mounting bolt threads (8), torque bolts to 30 ft-lb. Safety wire the
caliper mounting bolts (8).
•Position the Wilwood disc brake pads (10) into the caliper (6) and fasten with cotter pin (11).
Steel backing plate side of brake pad should face the caliper pistons.
•Repeat this procedure for the other wheel/brake assembly.
•NOTE: OEM rubber brake hoses generally cannot be adapted to Wilwood calipers. The caliper
inlet fitting is a 1/8-27 NPT. The preferred method is to use steel adapter fittings at the caliper,
either straight, 45 or 90 degree and enough steel braided line to allow for full suspension travel
and turning radius, lock to lock. Carefully route lines to prevent contact with moving
suspension, brake or wheel components. Wilwood hose kits are designed for use in many
different vehicle applications and it is the installer's responsibility to properly route and ensure
adequate clearance and retention for brake hose components.
•Specified brake hose kits may not work with all Years, Makes and Models of vehicle that this
brake kit is applicable to, due to possible OEM manufacturing changes during a production
vehicle's life. It is the installer's responsibility to ensure that all fittings and hoses are the correct
size and length, to ensure proper sealing and that they will not be subject to crimping, strain
and abrasion from vibration or interference with suspension components, brake rotor or wheel.
BEGIN BY SLIDING THE 0.032"
DIAMETER WIRE THROUGH TWO OF
THE HOLES (LEFT) THAT ARE 180°
APART. TWIST THE WIRE AS
SHOWN (BELOW) USING SAFETY
WIRE PLIERS. NOW SLIDE ONE
WIRE THROUGH TWO OF THE
HOLES (180° APART) AND WRAP THE
OTHER WIRE AROUND THE BOLT.
TWIST THE WIRES TOGETHER TO
FORM A PIGTAIL. SEE DS-386 FOR
COMPLETE DETAILS.
