abs problems

[pete]

I have just changed rotors and pads on 95 legacy L and I noticed a lot of iron filings clinging to the abs sensors at the wheels. It appears to be touching the notched wheel that the sensor is supposed to monitor. Could this be confusing the transfer clutches , causing torque bind? I cleaned them (a little) and it seemed to improve the condition. However , the problem is not always the same severity. I could be reading more into it than there is. I would like to here from anyone with an idea one way or an other. Pete a very nubie.
