[QUOTE="fiveohhhstang, post: 10255897, member: 25965"] 4WD/AWD is most definitely safer than 2WD in the winter. It's the morons who think it helps with every aspect of the car that get themselves into trouble. They think that just because the vehicle acts mostly normal while accelerating on ice and snow, it will act mostly normal when turning and braking. It's this carelessness that puts people in the ditch or on the sidewalk 4WD is more stable when accelerating, and more stable when maintaining speed, and that's it. 4WD has absolutely NO bearing on brake bias. How exactly do you think it affects brake bias? Do you think when the transfer case/center diff is activated, that some module or solenoid is told to determine how much fluid is sent to the front and rear brakes? That's not the case at all. 4WD systems simply determine how much driving power is sent to the wheels and when, which is why it's called 4 wheel [b]drive[/b]. Also, ABS does not give or distribute force to whatever wheel has the most traction, it simply takes away and gives back the force quickly. It does this by comparing a wheel's speed to the other 3 wheels (or other wheel in front only ABS systems) and if the speeds are too far apart, the ABS module will kick in, which simply pulses the brakes (either individual brakes or both on that axle) to whatever wheel is locked. This allows you to keep steering while braking, not stop in a shorter distance. Also, Tractor, the link you provided states the following: This disproves your point that 4WD affects brake bias. -ford_racer [/QUOTE]
