I have a 95 Chevy Silverado 4wd since new with 340,000km on it now.
Best machine I ever owned.
Never had any problem, except for the wipers, which I fixed by soldering the
cct board.
Problem is, ABS comes on just before it comes to a stop, even on dry
pavement and nearly every time.
Pads,rotors,shoes and drums all real good shape , I replaced them not long
ago.
I bled the lines all 4 wheels, but still happens.
Any suggestions?
Also, any way I could just de-activate the ABS without it displaying on the
instrument panel?
I drove 35 years without ABS and don't care if it works or not.
Common problem, may be covered under a recall depending on which
state you live in.
The problem occurs due to rust build up under the front wheel
speed sensors, the rust has pushed one sensor further away from
the tone ring than the other, this change in distance to the tone
ring causes a change in signal amplitude, the system reads both
sensor frequency and amplitude to determine wheel speed.
The fix is;
Remove both front wheels, brake calipers and rotors, remove two
of the wheel bearing attaching bolts that secure the inner splash
shield in place, this allows access to the wheel speed sensor,
remove the wheel speed sensor attaching bolt (4mm allen IIRC) and
carefully remove the wheel speed sensor.
Clean the area of the steering knuckle where the sensor mounts of
all rust, I plug the hole in the knuckle with a plastic plug and
sandblast with a speed blaster, but a wire wheel and/or a file
will do the job also. (do NOT allow debris to fall into the
sensor hole fouling the wheel bearing). Clean any rust that may
be stuck to the wheel speed sensor. Apply a light coating of
anti-seize to the sensor mounting area of the knuckle, re-install
the wheel speed sensor making certain that it seats fully and
squarely, re-install attaching bolt, re-install inner splash
shield and torque bearing hub bolts to spec, (use blue loc-tite
on the bearing hub bolts), re-install rotor and caliper,
re-install wheel and tire.
Thanks aarcuda69062 , that fixed it!
Very much appreciate your help.
