• Installation of this kit should ONLY be performed by individuals experienced in the installation and proper operation of disc brake
systems. Prior to any attempt to install this kit, please check the following to ensure a trouble free installation.
• Inspect the contents of this kit against the parts list to ensure that all components and hardware are included.
• Make sure this is the correct kit to fit your spindle. This kit is designed for direct bolt-on installation to standard midget type car
applications.
Disassembly (if applicable)
• Disassemble the existing front brakes. Raise the front wheels off the ground and support the front suspension per applicable racing
guidelines.
• Clean, de-grease the stock spindle while removing any nicks or burrs.
Assembly Instructions (numbers in parenthesis refer to the parts list and Figure 1 on the preceding pages): 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
while making sure all other mounting bolts fully engage threaded holes, where applicable.
•Install the caliper mounting bracket (1 for front mount) or (1a for top mount) onto the inboard side of the spindle mounting tabs using
customer supplied bolts and washers by first coating bolt threads with red Loctite ® 271 and sliding bolt through washer, then through
caliper mounting bracket and thread into the tabs on spindle as shown in Figure 1. The bracket must tighten squarely against the
inboard side of the spindle mounting tabs. Inspect for interference from casting irregularities, machining ridges, burrs, etc. Torque bolts
to specification.
•With the T-notches of the rotor adapter (2) facing away from the rotor (3), attach adapter to rotor using bolts (4), washers (5), and t-nuts
(6) as shown in Figure 1. Finger tighten. After all t-nuts have been installed, torque bolts in an alternating sequence to 220 ± 20 in-lbs
(~19 ± 1 ft-lb). Please refer to Wilwood’s data sheet DS-669 (available at
www.wilwood.com/Pdf/DataSheets/ds669.pdf ) for complete
t-nut bolt kit installation instructions.
•NOTE: When cross-drilled bolts are supplied with the rotor bolt kits, the additional step of safety wiring bolts is recommended. Safety
