The abs light on means you have a fault. A code reader should be able tell you what the fault is.

 

I don't know about your actual model, but on some vehicles the ABS light can double up as "Worn brakes" light as well.

Pads often have proximity sensors that warn when they are getting too close to the disks.

Either way, worth checking pad and disk thickness.

After that it may be ABS rotation sensor, but as Landmannnnn says, there should be an error code for that....

 

Thanks for the replies, my truck is a 06 Outlaw, it does feel like the pads are down but only when the ABS light goes out !!!!!

 

Your truck has wear tabs on the pads designed to squeal wen the pads are wearing. There is no electrical interface with them.

Abs sensors can fail as can the wheel bearings causing the ABS light. The front wheel bearings have a habit of failing and one of the indications it is happening is the ABS light coming on. Do you have a rumbling noise from the front bearings?

As Landmannnn points out it will be worth getting the system diagnosed to pinpoint the problem. You could always try this method which some say is inconclusive: http://www.nissan-navara.net/45-d40-technical-library/30528-diagnose-replace-abs-sensors.html

 

I do have a slight 'squeal' coming from the front brakes !!, but haven't noticed any rumbling noise !!

 

The front wheel bearings don't rumble until you are 40 miles from bearing collapse.. For a few hundred miles before there is a very slight throbbing on corners, if you jack it up and turn the wheel buy hand it feels slightly rough.

 

Problem solved !!!,..thanks for the replies guys, it was the left rear ABS sensor !!!!!

 

How did you locate it?

 

My local garage put his code reader on it !!
