I recently changed my pads and rotors and since the abs will kick in when coming to a slow stop. If I ride the brake to a stop abs usually kicks in under 7 mph. Even reversing out of my driveway the abs has kicked in. I changed the pads and rotors as the previous pads wore down to the metal. I barely drove the truck, knowing it was getting to the metal, so I parked it for a few days until I got the parts I needed.
I did a lot of researching on the abs issues and saw that a wheel hub nut not torqued properly could be the issue so I ensured it was torqued per specs 17 - 25 ft lbs, back off half turn,then 20 inch lbs. Then I read bearing issues can also be a cause so I changed both inner and outer bearings on both wheels, still the same problem. I took off the rotors again and cleaned the back area where the magnet reads the rotor/wheel speed and cleaned the abs magnet/sensor and this has caused the frequency of the abs turning on to be a lot less of an occurance. I noticed that the Abs usually kicks in now only when I am turning right. No indicator lights come on during the time the abs activates.

Any guidance wood be greatly appreciated

there is something wrong with one of the reluctor rings on the back of the rotors. pull the rotors off and make sure they are both intact, that the holes are spaced right and that there is no slag or casting defects in the holes for the reluctor ring

 

should have updated this long ago ..

Toreador4x4 you were correct, one rotor, had a damaged reluctor ring, was missed during installation, after taking it off and looking closely, with the replaced rotors, it looks like it was dented, and the holes had abnormal spaces, comparing them.

Thanks for the advice :) much appreciated.
