The F900 has an upper and lower wiring harness for the nose wheel anti-skid transducers. It is well known that these two wiring harnesses break down internally because of all the flexing and can cause intermittent anti-skid issues. What is NOT well known is that during the nose gear overhaul, these harnesses are not replaced but only cleaned and ohmed-out with a meter.
If it has been a while since the upper and lower wiring harnesses have been replaced, I recommend doing so during the next gear overhaul. This will help prevent unexpected anti-skid issues.
