Filed Jun 25, 2021 · Brakes · WA

Stopping, from between 5 and 10 mph, after a small drive - like a few yards.. the anti-lock brake engaged, made a pulsing / ratcheting noise and the brake pedal vibrated -- but the truck did not stop. I could not press down on the pedal any harder, and the truck took SUBSTANTIAL distance to come to a stop. --Dry road. -- I also have an ABS light on the dash from time to time.

Abs pump or speed sensor are damaged and not working on this truck. When my vehicle was turned off the ABS pump kept running causing me to pull the fuse for the ABS. Chevrolet is aware of this problem as I have been calling them trying to have them include my truck in the ABS/speed sensor recall which is on other trucks like mine. Chevrolet continues only to recall these trucks which were manufactured in the "salt states" only. As stated on: http://www.chevroletproblems.com/recalls/avalanche/2002/ service brakes, hydraulic:antilock recall for 2002 chevrolet avalanche recall announced august 29 2005 the federal safety agency reference #05v379000 number affected 1,353,718 summary: certain pickup trucks and sport utility vehicles may experience unwanted antilock brake system (ABS) activation. This condition is more likely to occur in environmentally corrosive areas. This recall will be launched in the "salt belt" states of connecticut, delaware, illinois, indiana, iowa, maryland, massachusetts, maine, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia, wisconsin and the district of columbia only. Consequence: this can cause increased stopping distances during low-speed brake applications, which could result in a crash. Fix: dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the peak-to-peak output voltage to ensure the wheel speed signal is within specifications. The recall began september 22, 2005. Owners may contact chevrolet at 1‑800‑630‑2438 or gmc at 1‑866‑996‑9463.

I am an owner of a 2002 chevrolet avalanche 1500. Lately I have had continued and consistent unwanted anti-lock brake (ABS) activation when traveling at low speeds and approaching stop signs, stop lights, and yield signs at or near intersections. The unwanted ABS activation appears identical and consistent with gm product recall 05068 and the federal safety agency campaign number 05v‑379 in which 804,000 gmc and chevrolet vehicles were recalled for unwanted ABS activation. The primary geographic regions affected appears to be the salt belt states. The problem appeared to be ABS wheel sensors not properly prepared prior to installation causing rust and/or corrosion to affect the wheel sensors. Although a check of my VIN does not yield any safety recalls on my specific vehicle, I believe my vehicle is affected by the same front wheel sensor corrosion issue as those vehicles listed in the recall. My vehicle avalanche which is one of the vehicles affected. I also reside in illinois which is one of the states affected. I am concerned this may cause and accident. I also believe this is a manufacturer defect and therefor the manufacturer should be accountable for any defect that may jeopardize consumer safety. I would like my wheel sensors cleaned and/or replaced per gm recall and at no cost to me.

At slow speeds, the ABS comes on without warning on dry pavement, so this is not a result of a slippery road surface. I have almost hit several things/cars. There was a previous recall for this exact issue (050068a), but the dealer says that the recall repair was already done and they will not perform the repair again. I can understand the dealer's position if this were not the result of a recall, but this seems to be an ongoing issue. The recall repair work was completed in 2006, and now in 2015, I am sure it has rusted again to the point that the same probelm is occurring. Rust in the braking system is a problem with this vehicle, as the brake lines have rusted out and failed twice already.

I purchased a used 2002 chevrolet avalanche 1500 in november 2014. I have had continued and consistent unwanted anti-lock brake (ABS) activation when traveling at low speeds and approaching stop signs, stop lights, and yield signs at or near intersections. The unwanted ABS activation has nearly caused several accidents. The unwanted ABS activation appears identical and consistent with gm product recall 05068 and the federal safety agency campaign number 05v‑379 in which 804,000 gmc and chevrolet vehicles were recalled for unwanted ABS activation. The primary geographic regions affected appears to be the salt belt states.

Although a check of my VIN does not yield any safety recalls on my specific vehicle, I believe my vehicle is affected by the same front wheel sensor corrosion issue as those vehicles listed in the recall. My vehicle is a 2002 avalanche which is one of the vehicles affected. I also reside in minnesota which is one of the states affected. I am concerned this may cause and accident. I also believe this is a manufacturer defect and therefor the manufacturer should be accountable for any defect that may jeopardize consumer safety.

When attempting to shift out of park the brake must be applied. The brake pedal sank to the floor and the brake telltale illuminated. Investigation identified a leak in the brake line just forward of the ABS module. Additional inspection highlighted significant brake line corrosion in the remainder of the system. The mechanic advised that a complete replacement should be done.

On 8/15/13 in the evening hours I was traveling in my 2002 chevy avalanche with my wife and daughter to a friends house when I went to stop for a turn. As I applied the brake I felt a little pressure then heard pop noise and the peddle went to the floor with no warning and the truck would not stop thankfully there was no one stopped to make the same turn. I was able to get slowed enough further down the road at a turn around and got stopped. I got out to look at what had happened and noticed brake fluid leaking from under the truck on the driver side upon further investigation I found the metal brake lines running from the master cylinder to the ABS module on the frame rail corroded severely, about half way down the line I found a large pin hole blew out the side and was leaking, at the time it happened I got no warning lights just brake to the floor. The vehicle has 150000 miles on it and for the last 5 years has mainly been garage kept averaging under 1000 miles a year the last 5 years. I have owned it since 2002. I keep this vehicle very clean, I am in a salt belt state and if I drive it in the winter I always wash under it frequently. I feel this is a direct manufactured problem I also own a old 77 pick up and it has the original brake lines in it and have hardly any corrosion on them. In researching for new brake lines I noticed alot of complaints with this issue and finally got here seeing a case opened way back in 2011. This problem is not going to go away and gm needs to address it before someone gets killed. After talking to my local chevy dealer there is not even a prebent brake line option to purchase.years ago chevy issued a recall for the tailgate cables in a quick fashion not sure why a brake problem that is more serious is taking so long to correct.

Im getting ready for a trip, from texas to ohio in sept. Pulling another vehicle. I decided to get the truck ready before such a long trip. It started fine, no signs of problems, I pushed on the brake before changing gears, and my pedal went to the floor. I could hear squirting and air. I knew I had a leak. I investigated the issue and found hydraulic fluid under the driver side seat. I found one of the lines had split above the ehcu unit, spitting fluid all over the under body. This line was severely rusted. The other lines have some surface rust but nothing like this line. It is no longer tubular looking and looks more like a wet stick with a lot of missing branches, and is much larger looking than the others. Also, I found a leak on a line that runs to the rear axle, on the driver side frame that was severely rusted like the one described above. Im pretty sure this is the line that is split, but its hard to tell, I cant find a diagram to help trace the lines. After investigating the issue, I rechecked my dash lights to see if an ABS or a brake light, none are on. I have contacted dealers and brake mechanics for repair, and have to have it towed as there is not enough pressure in the line to stop the vehicle. The truck was purchased in ohio. I would have imagined that they would be coated or stainless since it is a salt belt state, and im not sure why only one line degraded like it did.. This is a 2002 avalanche 1500 4wd with z71 off road package, it is expected to get dirty and wet. I believe better standards are in order to improve safety, and that there should, with this many people affected, definitely be a recall on the lines. Had it decided to hold up until my trip, this could have been very disastrous.
