Anti lock brakes

This may be the wrong place to ask this. It may be complex, and maybe not, but......<br>Does engaging 4wd bypass the anti lock brake systems on most trucks? Does engaging 4wd low only, bypass the anti locks, or does nothing bypass the anti - locks?<br>How would anti locks affect tire chain operation, or vice versa?<br>Would not being able to lock the brakes rob the benefits of chains in a braking situation?<br>Anyone run chains with anti - locks?<p>~Chuck Smith<br><p>----------<br>Chuck's Chevy Truck Pages - Snowplowing Central<br>http://members.aol.com/csmith669/plowcentral.html

On Dodge vehicles, it does not deactivate 4wabs. GM trucks it does some model years. not sure about Ford. Rear only abs is unaffected. I removed the controller for rear only abs on my Dodge, abs is dangerous with 4wd. <p>It used to be, at least thru 99 model year, 4wabs was unavailable with snowplow prep on Dodge and also with offroad package due to its unpredictable nature in 4WD.<p>Bill
