Wilwood Dynapro Rear Brake Kit For OE Parking Brake - Manual (Page 4)

Assembly Instructions
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 mount bracket assembly (1) should be installed first with clean, dry threads on the
mounting bolts. Mount the bracket (1) using bolt (6) and washer (5) from the backside of
the spindle with the threaded inserts facing the outside of the vehicle. The bracket must
tighten squarely against the outboard side of the caliper mount bosses on the spindle body.
Inspect for interference from casting irregularities, machining ridges, burrs, etc. After the
caliper, pad, and rotor alignment has been checked, and any necessary shims have been put
in place, the mount bolts should be coated with red Loctite
® 271 and torqued to 40 ft-lbs.
•Slide the rotor/hat assembly (2) onto the spindle. Check to be sure the hat seats squarely
against the hub. The hub must be free from any rust, debris, casting burrs, machining
irregularities, etc. Install a couple of wheel bolts (finger tighten) to keep the rotor/hat
assembly in place while continuing with the installation and clearance checking procedures.
•NOTE: Please reference the caution statement at the beginning of the assembly instructions.
Mount the caliper (3) over the rotor (2) and onto the caliper mounting bracket (1) using lock
washers (5) and mounting bolts (6). 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
0.035 inch shims (4) by placing them between the caliper mounting bracket (1) and the caliper
(3). Finger tighten and recheck alignment. Add as many shim washers (4) 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 3. Always use the same amount of shims
on both the top and bottom caliper mounting bolts (6). Loosen the two bolts (6) and apply red
Loctite
® 271 to the mounting bolt threads (6) and torque to 40 ft-lbs.
•Slide the brake pads (8) into the caliper (1) and secure with cotter pin (7). They should install
easily without interference with the steel backing plate side of the brake pad facing the caliper
pistons. Check that the outside radius of the brake pad is aligned with the outside diameter
radius of the rotor face. Add or subtract shims (4) between the caliper and mount bracket
(1) to gain the proper alignment.
•Remove the wheel bolts that were holding the rotor in place. Install the wheel and torque the
wheel bolts to specification. Check to see that the wheel rotates freely without interference.
•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. Wilwood offers a hose kit, P/N 220-8799,
which includes hoses, fittings, etc., all in one package for this application.
•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.
•In absence of specific instructions for brake line routing, the installer must use his best professional judgment on correct routing and
retention of lines to ensure safe operation. Test vehicle brake system per the 'minimum test' procedure stated within this document
before driving. After road testing, inspect for leaks and interference. Initially after install and testing, perform frequent checks of the
vehicle brake system and lines before driving, to confirm that there is no undue wear or interference not apparent from the initial test.
Afterwards, perform periodic inspections for function, leaks and wear in a interval relative to the usage of vehicle.
• Bleed the brake system. Reference the general information and recommendations on page 5 for proper bleeding instructions.
•Repeat this entire procedure for the other wheel.
