CHEVY SEEMS LIKE ABS NOISE

2008 Chevrolet Express

Brakes problem
2008 Chevy Express 6 cyl Two Wheel Drive Automatic 36900 miles

I purchased this van used with 33,000 miles on it.

I will be driving and comming to a stop and right before the van comes to a complete stop.
( with very light brake pedal pressure)
I hear a noise which seems to come from the front divers side wheel. It almost seems like the ABS is engaging.

I looked at the front pads and the rotors are clean and the smooth where the pads contact the rotor. I didnt pull them apart yet. Also the pads are as thick as the rear ones.

(Note) On another vheicle I noticed this if you drive over the white street markings for cross walks when wet.
This is not the case.


I looked at the rear brakes and noticed a rust build up (aprox 1/3 of the rotor) where the break pad would contact the rotor.
I just changed the rear brakes and rotors because of the rust build up. Thinking this would have caused the noise.

It did not correct the problem.

My next thought would be to pull apart the front pads and inspect.

Is there any service bullitens or other info on this break noise.

I bought a new 2008 Express 1500 and after 13,000 I began experiencing the same thing. Just as the truck comes to a stop it seems the ABS kicks in on the drivers side. Mine is covered under warrenty but I haven't had the time to take it in yet (it is a work truck). But my mechanic told me it's a know problem with Chevy where the ABS sensor gets gummed up and doesn't work properly. He said sometime they can just clean it or may have to replace the hub because the sensor is integrated. I plan to take it to the dealer within the next few weeks (when I get a break in my schedule) and will check back with this post after I get their answer.

I also talked to a garage since my van is out of waranty.
I was told the sensors need to be removed, cleaned, and clippep back in with die electric paste

If your van is all wheel drive yes the hub might need to be replaced
If it is 2 wheel drive the sensor can just be replaced

Thanks for your reply
