There is a button but in two wheel drive it does not completely turn off ever. There are mods to disable it though.

Short version is the older ones, pre-4wabs, had to go light on the rear brake pressure to prevent lockup...like 80/20...20% stopping in the rear. They controlled actual hydraulic pressure to attain the set percentage. Now they push the limit of the rears as much as possible, using the abs for electronic proportioning. Meaning, same amount of hydraulic pressure to all wheels, until skidding.  Notice that the newer cars don't nose dive as much as previous versions?
Funny thing is, they can't make the rears larger because then they would be prone to over braking, since they all have the same pressure applied.
Ok, maybe it wasn't the short version

Thanks for the explanation Ken. But why weren't you sleeping at 11:19PM instead of explaining why rear brakes wear faster.

That's the best time for me to put thoughts "on paper" ... when I'm completely beat down. Lol

I remember when this started to be more common on passenger cars back in the old les schwab days. usually RR would waste away the fastest, (hard cornering lefts are more common, making the outside rear wheel the one that gets the brake pressure to limit slippage). we'd see a lot of GM and mopars, Grand Ams and Intrepid and stratus cars with the same issues. 1/2 ton ram pickups were really bad and the customer wouldn't even notice until the ABS light came on and we'd find rivets cutting through the rotors. Shawn is right, to completely shut it off you'd need to mod it with a physical switch interrupting the signal.
