Anti-Lock brake issue

Hello, I have recently been experiencing a problem with the anti-ock brakes on my 2002 trailbazer LT. The brakes work fine when you initially press them, but as the vehicle is coming to a complete stop, and only withn the vehicle is rolling to a stop (right as the vehicle is about to completely stop), the anti-lock brakes kick in. No ice, rain, etc...normal temp and normal pavement. Anyone have any ideas?

I had my truck in the shop and they replaced the hub assembly and the problem went away. It was exactly as you described it.

That would be odd b/c I just replaced the hub assembly on the drivers side approx. 5000 miles ago Cost me an arm and a leg. I sure hope that not the case. Any other ideas? Thanks a million.

I do not think that you can do that.

Could be a wheel speed sensor gone bad. It thinks one wheel is locked up and the other one is still turning = detects one wheel lock-up and initiates pulsing.

my friend had a similar issue w/ his 02 tb. It would really kick in if you were stopping, and hit a bump. Turns out, a few months after noticing that, the wheel bearing went. Maybe its the sensor on the side you didn't get replaced?

If you have air tools and some mechanical ablity, you should do the hub yourself..and save some bucks (the only expensive part would be the hub)..

all you need is a 35mm axle nut socket (can get at autozone and Im sure other places) and a 19mm/18mm to take the caliper off and to get the three bolts that hold the hub, and I think thats pretty much it. (though I'm sure I'm missing something)

ABS and Hub problem

I recently encountered the same issue with my 02TB. I my ABS activated just prior to stoping, I replaced the hub and it was resolved (Unfortunatly the sensor is inside the hub and cannot be serviced without replaceing the entire hub assembly). It started again after about 4000 miles. To isolate the problem, I unhooked each wheels sensor one at a time and drove around the block. being shure to go fast enough to get the ABS to acticate (They are only on the front wheels, rear is on drive shaft) It was the same hub, and the berings had allready gone bad again. If you just did this recently you can do as I did and return the part because they are usually under warranty. They replaced it for free and now all is fine again. I dont think you will hurt anything by unhooking the fuse I drove like this for 10000 miles until I initially pin pointed the problem. But you will not be able to tell if there is any other problem with the brakes because the red BRAKE light will not go off until the fuse is replaced. Also one more piece of advice. The problem will eventually go away because the sensor will fall completly apart. Then the ABS light will come on, but the funny stoping will go away. Hope this helps with your problem I pulled my hair out for a long time with this. GOOD LUCK!!!!
