ABS is quite cablable now. From documents pertianing to my new vehicles ABS system: "Off-Road ABS The off-road anti-lock brake system (ABS) permits the front wheels to lock momentarily. The beauty of ABS is that it allows the driver to steer the vehicle in an emergency stopping situation; by locking only the front wheels, oversteer is prevented. However, many experienced off-road specialists do not want ABS when driving off-road. They depend on their own ability to lock the front wheels in loose gravel or dirt because the shoveling effect created by the front wheels builds up a pile of gravel or dirt in front of the wheels, causing the vehicle to slow down. Therefore, off-road ABS only acts at speeds less than 18 mph (29 km/h) on the front wheels, when driving forward and in low-range gear reduction." And "The off-road ABS permits the front wheels to lock momentarily. The wedge action created in front of the front wheels supports braking. The off-road ABS only acts: At speeds less than 30 km/h On the front wheels When driving forwards In low range gear reduction" I guess the manufacturer figures that ABS works as per normal in all but the most hideous conditions in the case of my vehicle, they have obvioulsy taken all surface types into account these days.
