Sweet, thanks man. After I replace the master, I will be doing this. What I don't understand is why bleeding the brakes helped with the issue? Maybe the vibration from the impact gun caused it to read correctly for a little while? I don't know, but I do remember having to do this to my other Silvy a while back. I'll let you know what the result is.

Is there anyway, other than looking at the WSS on the hubs to diagnose which one is causing the issue? I am thinking probably not, which means it'll be the last one that I do.

•Place a Digital Volt Meter (DVM) across the terminals of each wheel speed sensor connector.
•Rotate the wheel clockwise approximately one revolution per second. The minimum reading should be at least 350 ACmV's. If the reading is less than 350 ACmV's, remove the wheel speed sensor
probably just as easy to just remove the sensor and clean the mating surface...

^^^^thats what I did the last time, just have to be careful not to get any dirt in the hub where the sensor sits, thats the hardest part.

Just caught the second part of your question...yes, a sticking slider can act like a sticking caliper and cause a brake pull...and now that I think about it, a sticking/siezed caliper or slider pin could contribute to pre-mature ABS activation, as that wheel will be spinning at a different speed than the others when the brakes are applied and the EBCM will pick that up and activate the ABS.
