How to Install Wilwood Superlite 6R Rear Big Brake Kit - Black on your F-150

Modifications

•The dust shield needs to be modified as shown in Figure 3 to clear the new Wilwood rotor. NOTE: It is recommended that the dust shield be removed before modification, and the modifications be performed by a qualified machine shop.

Assembly Instructions (numbers in parenthesis refer to the parts list and Figure 1 on the preceding pages):

• The caliper mount bracket (1) should initially be installed with clean, dry threads on the mounting bolts. Orient the bracket as shown in Figure 1 and Photo 1, and install using bolts (2) and washers (3). Initially place one .029 thick shim (4) on each bolt between the bracket and upright, Figure 1. Temporarily tighten the mounting bolts. NOTE: The bracket must fit squarely against the mount bosses on the upright. Inspect for interference from casting irregularities, machining ridges, burrs, etc. Later, after the caliper alignment has been checked, the mount bolts will be secured using red Loctite® 271.

• Orient the rotor (5) and the hat (6) as shown in Figure 1 and Photo 2. Attach rotor to hat using bolts (7) and washers (8). Using an alternating sequence, apply red Loctite® 271 to the threads, and torque to 140 in-lbs. The bolts must be safety wired 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.

• Slide the hat/rotor assembly onto the axle hub. NOTE: The hat must fit flush against the axle hub flange or excessive rotor run out may result. Install three lug nuts (finger tight) to keep the hat/rotor assembly in place while continuing with the installation.

•NOTE: This kit contains distinct right and left hand calipers that must be mounted in a specific direction, as described below. Lubricate the caliper mounting studs (12) with lightweight oil. Initially place two .035” thick shims (13) on each stud as shown in Figure 1 and Photo 3. Mount the caliper (9) onto the bracket (1) using lock nuts (10) and washers (11), Figure 1. Ensure that the caliper is mounted so that the largest pistons are at the rotor exit end of the caliper, in relation to the direction of rotor rotation. Temporarily tighten the lock nuts and view the rotor through the top opening of the caliper. The rotor should be centered in the caliper, Photo 4. If not, adjust by adding or subtracting shims (4) between the bracket and the upright. Always use the same amount of shims on each of the two mounting bolts. Once the caliper alignment is correct, remove the bracket mounting bolts (2) one at a time, apply red Loctite® 271 to the threads, and torque to 77 ft-lb.

•Remove the caliper center bridge pad retainer bolt, nut, and tube from the caliper. Insert the brake pads (14) into the caliper, with the friction material facing the rotor, as shown in Photo 5. Check that the top of the brake pad is flush with the outside diameter of the rotor, Photo 6. If not, adjust by adding or subtracting shims (13) between the caliper and the bracket. After the caliper pad height is set, reinstall the center bridge pad retainer tube, bolt, and lock nut. The lock nut should be snug without play in the bolt or tube. Be cautious not to over tighten. Torque the caliper lock nuts (10) to 30 ft-lb.

Torque the caliper lock nuts (10) to 30 ft-lb.

• Temporarily install the wheel and torque the lug nuts to the manufacturer’s specification. Ensure that the wheel rotates freely without any 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. Carefully route hoses to prevent contact with moving suspension, brake or wheel components. NOTE: 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 flex line hose kit to fit this application, order P/N 220-15277 (M10 x 1.0 IF) for 2012-2014, or P/N 220-15276 (M10 x 1.5 IF) for 2015-present for vehicles without SVT wider track width. Hose kits include hoses, fitting, etc., all in one package for this application.
