Anti-Locks coming on when not needed

[yellow_edge]

Another small problem this truck has is when you are pushing on the brakes the hardest, like when your rolling up to a stop sign - when they are pushed in the most - not slammed but just the most for that brake, the anti-locks come on, like i can feel the pedal move forward and a bit of the grinding. I figure the ABS sensor may need to be cleaned and if so where exactly is it located? On the hub correct? What else could this be? Oh and the ABS light is not on.

Metal fragments get caught on the sensors, and cause problems with false triggering. Pull off the wheels, and you will see the sensor. There is a wire leading into it.

your wheels bearings could be bad too

 

[99splodersport]

your wheel speed on one wheels vs the other wheel may be different throwing a code which in turn would indicate a dragging bearing

Mine does that from time to time. As BrooklynBay says, pull the wheel off and you'll see a wire going to the hub, the sensor is held in with an allen bolt. My left front sensor needs cleaning now and then when the the abs starts coming on just as i pull up to a junction or something. I know then hub bearing is on its way out, but its not whining yet so i'll just clean the sensor for now
