how does it know if the brakes are hot? i'd imagine an algorithm or even analog charging circuit that times the rotor heat dissapation constant vs. the total activated time over some time period to decide when to disable it. and brakes were designed to be able run pretty damn hot anyhow. I was trolling over at the FJC forums and this same logic seems to be there as well.

to answer another question back a couple of posts, the ABLS works pretty well, but the locker with abls front was VERY noticibly better on a tough climb.
