I replaced the front rotors and the Pedal, brakes all seems fine at the end of braking when you just come to a stop the ABS comes on. Is this because the speed sensors are touching the rotors? how do I adjust them?
You can not adjust them you can replace them or take them out and file down the rust where the speed sensor sits.

go to ford dealership and have them scan your truck with a scan tool

have you check? the master cylinder. sometine when you get the rotors cut they dont come out right because they may be warped or to thin. if you did the job yourself you might have put the calipers in on the wrong side. this happens alot . if your rotors front and rear are fine then switch the calipers to the other side.

This seems like two different vehicles with two different problems. first the 1997 Ford Explorer- with new rotors and pad. I can almost guaranty that the rotor and pads that were replace are "after market" parts. If it is true,then the brake pad are at fault 95% of the time, the other 5% is the rotor. This because alot of after market parts are alot cheaper and are poorly manufactured out of cheap materials. I would recommend Motor-craft rotors and pads for this vehicle and that would take care of this problem. However if it is original parts on the car the dust shield on the hub may be to blamed, may have gotten bent into rotor during brake job. As far as ABS re-learn braking pattern that all BS that's absolutely 100% NOT TRUE. I am ASE certified in brakes and I never heard of such nonsense. As for the 1999 Explorer this problem is the ABS system applying it self prematurely. The sound that you feel on the pedal is when the ABS is active. Most common reason for this is a bad abs/wheel speed sensor, it could have gotten damaged during the brake job or grease or rust or something is between the sensor and sensor gear/ring. I have seen this many times before, just re-check everything. The abs becomes active because it detects a slip or brakes locking up or in your case maybe a false reading from sensor. Good luck and contact me if you need more help

Sounds like an abs sensor or a pick up ring. The sensor is normally bolted to the hub assembly and the pick up ring is on the end of the drine shaft on the front or the back of the rear bearing hub on the rear. Bet you the garage who did your brakes knocked a sensor with a hammer and damaged the wire to one of the sensors.

most likely have a bad wheel speed sensor- you can either take it to the local ford dealer to have them tell you what sensor it is, or you can remove the abs fuse and it will disable the abs alltogether. your brakes will work normaly, they WILL lock up if you stop fast.hope this helps and good luck
