ABS Warning Light On and/or Erratic ABS Operation on Chevrolet Tahoe

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.

Erratic brake pedal with grinding and pulsating. Can act like it won't stop. Metal-on-metal grinding sound.

The brakes were worked on but this problem still persists. ABS light on, sometimes steady, and you can hear them activating when first starting out. One time they seemed to 'lock'.

ABS activates for no reason. Mostly around turns. Will activate either with, or without the brake being applied.

Abs and brake warning lights come and go with no actual braking failure. Come on and off randomly. Wheel speed sensor replaced.

All four brakes locking down while driving. Engine in overdrive to account for the increase in resistance. Stopped at red light and smoke engulfed the area around my Tahoe. One of the codes on the computer says transmission is slipping. The vehicle is in the shop now... We shall see!

There has been a recall for this (specific brands are listed). I just started having this problem and my tahoe is completely out of commission now until I can take it in to see if it was part of the recall. Fingers crossed.

I talked to the Bosch engineer who designed the anti-lock brake system. He told me that one of the sensors at one of the wheels was defective - probably the LR. He said that was a comon problem.

The abs light stay on and the other brake like jump on and off, then after driving a mile the brake padel get hard to push down n the brakes lock up on me, then when I park n turn the Tahoe off I'll spray the front brakes with cold water then they will loosing up.
The abs lights coming on and the air blowing cold sometimes hot air. This is 2 different problems but happened at the same time.

Abs just came on the other day getting it checked out sounds the same as many others on here. Hope it's not to expensive to fix. We will see

My brake and abs light come on randomly when I brake or hit a bump. It won't go of until I shut the Tahoe off.
ABS failure and brake light along with alarm go off every time you start the vehicle

sometimes when i brake it feels like it stalls and isn't going to stop and that went on for almost a month and it only happened a few times so i thought nothing of it then my ABS light came on and i read up on it and became concerned that I've been driving like this with two kids in the car. I called my local dealer and my vin number doesn't have a recall on it so it has to come out of pocket which can be pricey.

erratic abs activation, particularly at slow speeds. Affects ability to come to a complete stop.
Been trying to fix the problem, no luck. Replaced rear wheel cylinders, abs brain, hub and bearing assemblies on front, abs sensors 3 separate times, bleed system. Don't have a dump valve cycling programmer. The abs kicks in at 1 t0 3 mph and pedal goes down and a grinding noise with pulsating coming from front brakes.
