Re: ABS in reverse (was 10/10ths)

[audistuff@juno.com (Paul R Anderson)]

ABS, particularly the early ones relied only on wheel sensors to tell
if a wheel was locked.  As you said, if all four wheels are locked, the
ABS computer is thinking, "No problem, we're stopped!!"  It should have
picked up the motion but if you were going too slow, it may not have.
I think you answered your own question.

keep up with the list very well.
