96 Explorer brake issue

[JamesHolt]

I have a 96 2wd, auto,5.0
I just had to replace the wheel bearings on the front, did both sides, inner,outer bearings and races + seals..
I didn't see any damage to the slotted disc for the anti-lock, but lately when I get just about stopped the anti-lock kicks in for a few seconds..
I have no warning lights..
Anyone got any ideas on where to start looking???
I don't have much experience with the anti-lock systems, never had an issue until now...

Nobody??

ABS sensors?

Not sure how they are on the 2wd.
They should basically be just a wire so, shouldn't be expensive to replace.

I'd drive it for a bit and if it doesn't go away... sensors.

did the same thing on my 96 EB two wheel drive changing the bearings on the the front. didnt have your problem but later the abs started kicking in and it was the sensor the t went bad.like rodman said drive it for a while and see what happens

No guarantee to help, but lift the front tires off the ground and remove the small bolt on each sensor to clean the magnetic sensor heads. Spin each tire slowly while spraying brake cleaner with the tube in the sensor holes to clean
the slotted tone rings followed with compressed air. Seemed to slightly reduce my slow speed brake pull which turned
out to be a sticking caliper. For those interested this applies to RWD only, 4WD ABS sensors are integrated in the hubs.

For some reason I think I've taken an ABS sensor out of a 4x4 hub, I think it's held in by an allen head bolt. - could be wrong

that is true, provided it isn't rusted in.
the trigger ring is inside the bearing and kinda out of reach.

to the original poster, clean the trigger disk and sensor, re-adjust the wheel bearings.


the anti-locks work by the magnetic sensor detecting the spokes of the trigger disk. both the frequency and the amplitude of the signal increases with speed, decreases as you slow down. the frequency is what measures speed, amplitude is just how strong the frequency signal is..
so, as the sensor is watching the frequency of the spokes going by the sensor the strength of the signal weakens as you slow to a stop. with the weakest signal being as you slow to a stop, that's where its the most difficult for the sensor to properly sense.

if you replaced the big bearing races there is a good chance you bent a trigger disk. if they are bent away from the sensor the signal weakens. 1mm can make a big difference.
