Flyer146,
What Lemurian said is quite correct. The autobrake was not providing the decleration that was set/required! You are also correct that the autobrake could have been working but because of a slippery runway could not provide the required deceleration. However the "NO DECEL" is a standard call and was missed out! Maybe the announcement of "No spoilers" & "No decel" would have woken the PF to the real reason or prompted him to go-around.
