Abs issues but no light.

[Newblue]

2000 V6. Just in the last few days the abs will kick on with light brake application but not when braking heavy. No abs light so this is an odd one for me

The signal from one of the wheel speed sensors is probably marginal. I don't think that you will find it with a scan tool. It should be easy to find with an oscilloscope, but I am going to assume that you don't have one of those. (Note that you can get a really cheap one for about $30 that is good enough for this problem.)
You might start by inspecting/cleaning the tone rings and sensors.

I'll start with the right rear. The pad material fell off the backing plate and found a bunch of metal shavings in the lip of the wheel. Found the pad material in my driveway. Lol

Got it figured out. Corrosion between the rear sensor and mounting bracket. When it would get wet it would expand and push the sensor away from the tone wheel creating too much of an air gap. That was a tough one to figure out because it would act fine when dry. Lol

Dielectric grease does wonders for electrical connections.

That's a botched brake job on that one rotor & pad.

Rust caused the pad material to separate from the backing plate. Notice the second pic.
