PostSubject: Question about RABS   December 10th 2009, 8:18 pm

What is the point of only having rear anti-lock brakes? I thought the whole point of ABS was so that you could steer while braking. Hard to do that when the front wheels dont have ABS, but your not supposed to pump the brakes because you have RABS?

So what am i supposed to do when braking hard and having to steer?

Another variation is the "single channel" rear-wheel only ABS system that is used on many rear-wheel drive pickups and vans. Fords version is called "Rear Antilock Brakes" (RABS) while GM and Chrysler call theirs "Rear Wheel Anti-Lock" (RWAL). The front wheels have no speed sensors and only a single speed sensor mounted in the differential or transmission is used for both rear wheels. Rear-wheel antilock systems are typically used on applications where vehicle loading can affect rear wheel traction, which is why it is used on pickup trucks and vans. Because the rear-wheel antilock systems have only a single channel, they are much less complex and costly than their three- and four-channel, four-wheel counterparts.

In short John, its to keep the rear wheels from locking up when your truck is loaded.
