  Bolt Hex.Head

• Description:

  This is a genuine Ford caliper support bolt, catalogued under base number W714660 with the S439 hex flange head specification, used to fasten the front disc brake caliper anchor bracket to the steering knuckle on the Explorer and its Police Interceptor Utility variant. The bolt carries the clamp load that holds the caliper mounting bracket rigid against the knuckle, anchoring the brake caliper so it does not move under the heavy reaction forces generated each time the brakes are applied. Technicians reach for this fastener during caliper, bracket, or rotor service, and after a knock, clunk, or uneven pad wear points to a loosened or corroded support bolt that has let the bracket shift. Because the caliper anchor is a primary brake structural joint, a stretched or under-torqued bolt can compromise braking feel and safety, so accurate torque is critical. Ford classifies this as a fastener that should be replaced rather than reused once removed, since the clamp load on a high-strength brake bracket bolt degrades after the first tightening. Manufactured to Ford engineering specifications, it provides the correct thread, length, and flange bearing surface for the original knuckle bore and installs without modification. Always tighten to the published torque value, replace both anchor bolts together, and inspect the bracket, rotor, and pad hardware while the caliper is off so the front brake corner is restored to factory integrity.

• Notes: Part cannot be reused/reinstalled.
