Problem Description and Possible Solution

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

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.
Brakes get hard and growl a slow speed.
Feels like a beach ball under brake pedal. Happens more when it's cold. Retards breaking and have to pump pedal to help resolve issue.
ABS activates at slow speed, Need to pump brakes with both feet to control stop on my 2000 Sierra 1500
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.
front right break locked up, replaced breaks,caliper,rotor, and bleed breaks , locked up again burned breaks some, replaced breaks again re-bled brakes. abs lights came back on and my next step is to replace sensor not sure if that will take care of the problem.
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!!
(rebuilt engine) brakes cause bouncing effect of pedal and vehicle. rotors, calipers, brakes all been replaced but not fixed. There is no ABS indicator light illuminated.
Left front wheel ABS wheel sensor melted. Replaced it and the shield. Also, replaced caliper hoses and brake disc pads, wheel bearings and rotors.
ABS light came on after bounding through a snow bank. Told I'd need to replace ABS on front left...expensive and haven't done repair yet.
i hope the reps at chevy read these my loyalty is startin to slip chevy has some of the most reported issuse this sensor cost almost as much as the whole hub assem come on chevy help us help u by a recall for bad ideas and failure to test better leaving ur loyal cust to fix ur mistakes
I have brake light and abs light both illuminated at all times when truck is cranked havent discovered problem yet but since its electrical obviously.
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.
