In answer to topic title, if you have ABS, the car won't like up like made under hard braking, and the pedal will pulsate under hard braking.
You can also check the lines running from your brake master cylinder and trace where they run, if they run into another unit before going to the calipers you have ABS. If they run straight to the calipers from the BMC, you do not have ABS. OR easier still, if you have two lines coming out of your BMC you have ABS, if you have three lines you do not have ABS.
