1998 Chevrolet 1500 Pickup 168,503 mi,
ABS braking was working whenever it felt like it. Lights on and check engine came on. Failed and the ABS code came up. Replaced brake pads, calipers, rotors and the speed control sensor. They now are worse and can not drive the truck. When pressing the brake, the truck pulls so hard to either left or right(it chooses)and shakes violently, with brakes not stopping truck at all. What else can be the problem? Need input and suggestions please.

Brake light on dash comes on and stays on all of the time. No difference in braking system. If I unplug from the ABS system and then plug back in the light goes out and stays out for 2 or 3 days than comes back on. Can't figure out where to start looking.

ABS would activate when not needed at low speeds, then quite working and dash light would come on. Replaced speed sensor and it solved the problem.

Both front wheel speed sensors register as bad when scanned. i guess it's good(?) to know this is likely 2 bad sensors.
Brake indicator constantly on.

turning vehicle tightly left or right will cause brake failure. pumping the brakes after turn will fix.

I replaced the whole front end, including a new wheel hub. I had replaced the pas. side before, but in the process of the rebuild, my helper broke the speed sensor wire. I put the old one back on for a fix. After test driving it growled and kicked off the abs light. I then replaced both rotors and pads, bled the system and tested it again. Still the same problem. A brake shop told me to try and fix the old wire, my only option is jb weld. I cant afford another hub at the moment, so if any one has info please help!!

Speed sensor failure.
Those of you with ABS problems on GM vehicles, where ABS activates on dry roads at slow speed. the problem is one or both of your front wheel sensors. I didn't have to replace mine, I simply pulled it out of the hub, stick a small rag in the sensor hole to keep debris out, then emery cloth or sandpaper all around the base where the sensor sits, also clean the sensor. Rust builds up under the sensor & the base, lifting the sensor slightly & changing the gap between the end of sensor & sensor wheel that is on the bearing. If this doesn't work, replace the sensor. most can be purchased without the wheel bearing. I hate ABS. If you want to stop the erratic ABS behavior in the brake pedal, the above info will correct that, or what I have done before I cleaned sensor, is remove the ABS 60 or 40 amp fuse from the fuse box under the hood. This will shut down the ABS system completely, your ABS light will stay on, but you now will have normal brakes (works great) long as you don't mind looking at the light. In Mass you still can get an inspection sticker with this light on. I leave the fuse out now all the time, I like the brake operation better without ABS. Hope this helps

I'm not sure about the mileage. I've had this truck for 15 years now, and when this occurred, had it checked, part replaced, but it stayed on anyway. I've tested whether the ABS works by speeding up and abruptly stopping and it's been fine.
