Low speed ABS trigger

[spaul100]

Apologies for jumping a thread. I've included prior post and answer here to update anyone with similar issues.
j cAT suggests sensors or wheel bearings. How does one know if wheel bearings are worn and how difficult are they to replace? When writing about sensor pads I mean the machined flat spot where they sit. Did clean corrosion away carefully to good metal.
Thanks j cAT.

Can you offer advice on the ABS system. 2001, burb, 1500 4wd when stopping the ABS kicks in just about at one or two mph. Have replaced pads, rotors, etc. Put two new to me, front sensors on and still no difference. Did clean the corrosion down to good metal on the sensor mounting pads.
Hoping not to have to replace the ABS module. Any help appreciated. Have not checked the transmission sensor nor the codes. WHile not sure if my new code reader will even read the brake codes.

remove connector to abs front sensors and rotate tire should get 350-500mv ac if too low may be sensor or bearing the low side will be the bad side... this is most likely the problemn area as abs comes on at low speeds......sensor mounting pad????????
