A Ford F-150's brake rotors are the disk portion of the pickup truck's disk brake system. When performing brake and rotor maintenance on the F-150, seating the wheel properly and tightening the lug nuts to the correct torque specifications will help ensure that the wheel is flush against the hub and rotor and that the new brake rotor will not wear unevenly.
For F-150s manufactured since 2000, tighten lug nuts to 150 ft-lbs of torque. Lug nuts on these F-150 models are 14 mm.
For F-150s in the model years 1997, 1998 and1999, tighten lug nuts to 100 ft-lbs of torque. These models have 12 mm lug nuts.
Start at any lug nut. Working in a circle, tighten opposite lugs in tandem before moving to the next pair. This will ensure that the pressure placed on the hub is evenly distributed during the tightening process.
After driving your F-150 100 miles, recheck the torque of each lug nut. Tighten to specification any lugs that are loose. Road vibration and alloy flexing may cause some lugs to loosen.
