Is this a 2wd or 4wd? I think there was a GM bulliten where there was rust build-up on the reluctor wheel or the abs sensor in the hub had rust on it.
I am having a similar problem. I replaced both wheel bearing assemblies on my 99 2500 Suburban 4x4 about 6 months ago. When I first start up and go I will drive a little and then when I go to stop the brake pedal starts vibrating and the pedal goes to the floor and I can't stop. Usually the ABS light comes on and the brakes work again but without the ABS working obviously. The light goes out eventually and then it might happen again. Anybody have any ideas before I wreck?!?!Is this a 2wd or 4wd? I think there was a GM bulliten where there was rust build-up on the reluctor wheel or the abs sensor in the hub had rust on it.
