JCV8 is correct, you should have your foot planted firmly and steer yourself out of trouble, pumping the brakes can be used for normal slowing/stopping.
I nearly hit a roo the other day, he was on a median strip at 8.00am, 4 lane highway, in the burbs. As they do, he jumped in front of me at the last minute, and I found out ABS does work, roo skidded to a halt as I was steering away (under full brakes) from the impending collision. Live roo, unmarked car. ABS rules, baby!
