Erratic brake pedal with grinding and pulsating. Can act like it won't stop. Metal-on-metal grinding sound.
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.
abs coming on for no reason at 1 to 3 mph when braking

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!
My ABS/brake light is on. When they came on, my tahoe is hard to take off. And now the transmission sounds like it's not shifting gears. How to I fix the problem.
When I'm hitting the brakes, or slowing down on a turn usually within city limits, the brakes or the truck grinds essentially. I always called it growling at me. Then the brake light came on and it seemed like I was pushing my brakes all the way to the floor which made me think that I was using only back brakes. It is not currently fixed and I'm looking for a good mechanic that's easy on my wallet.
Driving truck then felt like brakes locked up. grinding and vibrating
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.
Around 5k miles ago the abs light came on. Now I know the cause
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.
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'.
The lights of ABS and BRAKE turn on 3 or 4 times a week, so, when that happens I stop, turn off the engine,and i start again, so they don't stay on
Abs light comes on and off while driving. Brakes will grind and brake pedal will 've hard to push down. Does not happen every time brake is applied.
i pulled in a grocery store parking lot, pulled into a parking spot, hit the brakes and the pedal refused to go down. it was as if the pedal was sporadically pushing back
ABS light comes on and ABS breaks are engaged erratically in dry conditions
when coming to a stop pulsating abs kicks on like it wont stop (all low speed) seems like front brakes
While driving and coming to a stop and just before the vehicle comes to a stop . Break peddle gets soft and goes to the floor and a slight pull and peddle goes to floor , at the same time my voltage drops at according to amp gage and headlights dim. Assuming speed sensor is at fault . Once in a while I'll get an ABS and break alarm flashes on dash.
Abs activates at low speeds for no reason
