Abs brakes cut out leaving you with little to no brakes. No warning light appears. This continues on and off over time. Then that abs warning light came on. When the warning light was on, brakes worked just not abs. Light would go out and back to the original issue. Took it in to dealership when the light remained on. They reset the light and told me every thing was fine. And charged me $$$. Abs brake warning light can right back on. Had the manager drive it. Told me it was fine, brakes worked well. The abs warning would go in and out. Removed the abs fuse, so I could depend on being able to stop, without having to worry about the abs cutting in and out for a few years. Watched for recalls, nothing appeared. Noticed on blogs, others were having the same issue. Took it to a great mechanic! who verified there were no leaks in the brake lines, replaced one line that had been known to have issues on this type of truck and verified there were no air bubbles on the lines. Still same issue, then replaced the computer system for the abs. No codes ever came up on the computer system that I can recall. Had more issues with the abs. Would go to stop, (generally on a hill) then when it came to the final stopping, I had no brakes, had to slam on the brakes to stop. Abs brake warning lights never came on. My mechanic looked and looked and relooked into this. Found from others that blogged that they had similar issues, that one or both of the abs brake sensors were not responding evenly causing an issue. Changed out the sensor. All is good now. This issues could have put and my family in danger a number of times. I was blessed to avoid a few accidents by driving far enough behind people and or had an emergency line to pull into when unable to stop. Hope a recall comes soon for these issues to prevent someone from being killed. These took place from about 2015-fixed 2020. Email me with a report number and where I can upload info at a later date, I will do so.

Suburban is extremely difficult to stop or will not stop at stop signs. Pedal goes to the floor for emergency stops on highway and going down hills. Brake pedal is very soft. Abs system activates at slow speeds and/or may pull vehicle very hard to the left. Nhtsa recall issued for this problem only in certain northern states but not in washington state where we have high corrosion from natural ocean air and extreme winter mountain driving with deicers. Though brakes have been repeatedly serviced since new this safety problem persists and is getting worse.
7 o' clock in the morning heading to work making a left turn into parking lot apply the brakes, pedal want to the floor, avoid hitting the car in front of me, jumping the curb came to a stop, checked underneath, oil leaking. Call for a tow truck. . Mechanic checked the brakes lines all need to be replace.
Upon leaving my driveway to the first intersection the brake pedal went all the way to the floorboard. I got the truck home and parked it. I thought the anti-lock part was probably the problem. Expensive as that part is I just let the truck sit. One day I left a piece of cardboard under the truck and isolated the leak to two rusted out lines at the plastic clip on the frame. This area must hold moisture and doesn't dry-out, allowing it to rust.
1999 GMC sierra pickup regular cab 4 wheel disc brakes. Truck would not come to a complete stop at a traffic light, speed less than 5 mph. Pedal vibrated then went almost to the floor. Truck bumped into car in front of it causing minor damage to car, very slight damage to truck. Roads were clear and dry, day was cold but sunny.
