• Description:

  This is a genuine Ford disc brake caliper mounting bolt catalogued under specification W716761-S439, used to secure the front brake caliper anchor bracket to the steering knuckle on the F-150 pickup. Catalogued as a Caliper Mount Bolt, this M14 by 40mm hex-flange bolt clamps the caliper support to the knuckle so the caliper stays rigidly located over the rotor and the pads track squarely during braking. It carries the full braking load transferred through the caliper, so it must hold precise clamp tension to keep the assembly from shifting under hard stops. Drivers replacing this bolt are usually performing a brake job, swapping calipers or pads, or addressing a caliper that has loosened, causing uneven pad wear, a pulsation, or a knock from the front wheel area. Ford flags this as a one-time-use fastener, meaning it should be replaced rather than reinstalled once it has been torqued, because the original clamp load cannot be guaranteed after removal. Manufactured to Ford specifications, it provides the correct thread form, length, and flange bearing surface for the F-150 knuckle and installs in the original location without modification. Always torque to the published value in the proper sequence, and inspect the caliper bracket and knuckle threads before installation. Using the correct mount bolt preserves brake safety and the factory feel of the pedal.
