Notes

Note:  When the caliper bracket is affixed to the spindle properly so that the bracket is square to the spindle and brake rotor face for proper caliper alignment and installation, the welded roid that features female threads in the caliper bracket will be offset inboard or towards the centerline of the vehicle in relation to the centerline of the caliper bracket plate.
Some parts are not legal for use in California or other states with similar laws/regulations
