Antilock brake engagement at low speeds I own a 2000 chevy Silverado LS 1500 4-dr, VIN 1gcek19t4ye408437. I have had it into a brake shop twice over the last 3 years for the antilock engaging at low speeds (3-5mph). The antilock alarm does not light up. I finally got disgusted when it started doing it again this winter and pulled the fuse for the abs system. Both repairs were performed at the brake and alignment service center 1770 barlow, traverse city, mi 231-947-2600. Each time they identified the abs sensor for a single wheel engaging inappropriately at very low speed. I do not have the exact dates of the repairs handy, but can get them from the above business if needed. The incident date below is my best guess at the moment for when this first started. I can tell you that there is great potential for low speed accidents at intersections with this defect. When the abs system engages, the vehicle does not brake effectively at all. The brake pedal has to be released briefly and then pressed again to engage the normal braking action. I can't count the number of times I have had to release and than stand on the brake pedal to stop in time without rear-ending someone.

When brake applied at slow speed, truck failed to slow down with constant brake pressure. I almost rear-ended vehicle in front of me. Pavement was clean and dry. I have also been getting abs chatter when stopping at slow speeds. Dt.

Problems with the brake pedal and abs system. Also stated that everytime he is driving the vehicle on a flat surface every thing is fine but if is a rough surface the brake pedal will go down to the floor and it won't stop. Dealer was contacted and stated that it is normal on those vehicle but consumer doesn't feel safe. Ts.

Many people simply pull fuse or disconnect abs pump power and go without abs because of the cost of repairs. Due to the number of vehicles experiencing the same failure, this could be a significant safety problem. Dt.

I have talked with over 50 people just in the knoxville area that have had this same problem - a "burnt out electrical delay in the abs unit" - costing upwards of $1000 to fix. I have put less than 5000 on this vehicle from my date of purchase earlier this year. I am still under dealer warranty and I will be demanding a refund and an explanation. If so many people are having this same exact problem, some people told me it is caused by water from the left tire splashing on the speed sensors, vitrually rendering them useless, then why isn't there a recall? dt.

Consumer noticed the at home didn't have antilock brake system. Dealer has not been notified yet. Please provide further information . Mr.

The break pedel becomes rock hard and the truck will not stop have to use the emergancy brake when the antilock brake fuse is removed the brakes work fine. Before I removed the fuse was almost in many crashes, if I had not used the e brake!!!!!!!!!! dt.

The abs motor keeps running after the truck is cut off. The only way to stop it is to pull the fuse, so I have no abs. Gm finds ways to get out of their warranties and could careless that they are creating safety problems. When you pay $26,000 for something you expect it to work and extended warranties should be just that instead of ways to suck out more money from buyers. Dt.

Abs module fails, and antilock brake are inoperatable. Module is located under the truck on the frame rail. This probably causes water to short it out. Dt.

No summary. Dt.

Ecbm shorted out. Located on top of abs brake pump, attached to frame under drivers seat. Dealer wanted $1100 to fix, $770 part. Bought part $409 (discount) had installed for $300, called Chevrolet service help. No help!! got other recalls fixed at dealer. Dealer nor me couldn't get hold of chevorlet service help. Ecbm located where water can damage it. Seems to be a problem with 1999. Dt.

Abs pump continued to run with vehicle off. Abs/brake light remain on seems to be a very common problem. Dt.

Consumer states that the module that controls the abs failed, resulting in no abs brakes, when needed. Dealer contacted, this is a common problem. Ts.

The module that controls the abs is failing to turn the abs motor off when the truck is stopped. I have contacted chevy and they have said there is nothing that can be done but said this is a common problem with these trucks. It was not mentioned at the time of purchase. I have searched the internet concerning this issue and it is filled with message boards complaining of this same issue. How much more has to be done to start a recall campaign for this? dt.

Antilock brack module failed at approximately 42,000 miles.

The abs pump continues to run even after ignition is turned off, thus draining battery. Inorder to stop pump the abs must be disabled resulting in a dangerous situation, driving the vehicle wih compromised stopping ability which can result in an accident causing bodily harm or even death.

The failure of the abs ecu and pump are due to the location of the unit which is located under the vehicle below the drivers seat. The abs unit is in the direct spash path of the front left tire. I dont think the engineers that designed this unit took into consideration that the abs ecu and pump get a presure wash evertime it rains. When the unit failed I went to the dealer in norman, ok (mark heitz) and talked to the service manager about it. He told me that they replace these units quite often because they get water in them and short out. Not being familiar with the unit I asked more question. The ecu is sealed to the pump and when water enters through the seal it shorts out the ecu and starts rusting out the pump. The rust in the pump concerns me because it can potentialy contaminate the brake fluid and cause brake failure. Tom-the service manager at mark heitz exact words "the pump had water in it and it was full of rust" mark heitz phone number is 405-321-7021. The other failure is the parking break. I dont think it ever worked the day it came off the dealer lot. The first time I tried toused the parking brake was at beaver lake in arkansas on a camping trip. This was last summer -summer of 2000-. I parked on a steep hill and applied the parking break . The pedal went to the floor rater easily and I thought nothing of it, that was unitll I got in the truck and tried to put it in drive, I had a hard time getting it out of park. The nut on the tensioner shaft to the parking brake system under the truck is completely tightened. The cable brances off to each rear caliper and is each attached to a lever on the calipers. I've observed the levers move and still no parking brake. The levers look to be fully engaged, that is the levers are pulled as far forward as possible by the cables. It's a great feeling to know that you've paid thirty grand for a vehicle with problems. If you have any question I can be reached at any time on my mobile 405. 205. 6621-thanks.

Abs failed on wet surface,spun 450 deg,after spin failed to stop vehicle. History: appoximately 4-6 times over a nine month period, when the brakes were first applied they did not appear to work. Upon releasing the brake and reapplying, the brakes then worked. Then over three month period the brakes began to feel choppy when stopping. The vehicle was taken to the dealer and all four rotors needed to be turned (only 10000 miles on vehicle). Two days later on a wet surface, going 16-20 mph on a right turn with a slight uphill grade, when the brakes were applied the back end of the truck came spinning around in a clockwise direction. At 90 degrees the brake was released. The truck spun a total of 450 degrees. Then the brakes were applied hard, you could hear the sound of the abs but the truck did not respond at all, there was no braking action. The vehicle crashed head on into a guard rail. The entire front bumper needs replacing. Fortunately no one was injured.

When stopping on rough road the brakes released and then locked up. I talked to the dealer and they advised they haven't received any complaints on the brake systems. Problem was not resoved.

The abs system/pump made a terrible sound and the warning light came on inside the vehicle. I contacted the dealer who stated just to unplug the abs power supply but the brakes were fine. Another friend, julian scaff, has the same make/model/year truck and has had the exact abs failure. Both were at approx. 45,000 miles. I have also had problems with the rear brakes locking up and not unlocking for a few minutes. This has caused untold wear and reduced fuel milage considerably. These are serious safety issues.

Vehicle would not stop during emergency situations. Many times I slammed on the brakes and the truck will stop at first a second and then the brakes would let go and the truck would still go. I have to put the brakes to the floor and then the truck would slow down. I have taken the truck to 3 different dealers in san diego and none of them knew the problem. One dealer told me to gently apply the brakes for the vehicle to stop properly, but I'm sorry, I can't do that during a panic situation. The has failed at least 5 times and one time when my pregnant sister was driving, the truck would not stop through a parking lot, so she crashed into another vehicle. Don't know what do now. Truck is already over extended warranty. We plan on selling the truck soon and buying another because this one is not safe.

Front brakes don't have a sure stop when going over a bump. Dealer has seen vehicle several for the problem, but can not find anything wrong.

The brakes get hard and won't work, then they suddenly lock up. This has happened to us several times, and to the service guy once. The first two times it was in for service, they couldn't duplicate the problem. After they went out on the service guy, they replaced the brake booster. They went out again, and they replaced the master cylinder. They just went out again, at an intersection, and we almost had an accident. It is back at the chevy dealer, but they don't know, and chevy doesn't know what to do with it. This is a dangerous situation. Is anyone else reporting problems with these trucks?.

The anti-lock brake system fails on dry pavement when a bump or separation is contacted in the pavement during the braking operation, resulting in lost of braking capacity. This occurs usually between speeds of 25-35 mph during braking while the vehicle is slowing down. If during that time, a bump or rise occurs in the pavement, it seems like traction is lost and braking capacity is diminished, resulting in increased stopping distance. Often this occurs at stop signs and intersections, occasionally when attempting to turn, resulting in hazardous handling. Dealer has been notified several times, and attempts to repair by replacement of gasket on fluid reservior lid of master cylinder dimished the symptoms but did not rectify the problem. Hazardous braking situations continues when brake failure and/or increased stopping distance on dry payment occurs.

Abs is too sensitive, especially on slippery or bumpy surface which causes a longer stopping distance. Consumer was told by service writer for Chevrolet that z71 models are known to have this probelm.

Abs brakes severly resist the operators attempts to bring the vehicle to a stop at slow speed. The brake pedal vibrates but increased pressure by the operator will not being the vehicle to a stop. You have to take your foot off of the pedal completely, then slam it down with force to get the truck to jerk to a stop many feet past where it would normally stop. This frequently causes a loss of control at slow speed such as pulling up to a gas pump or stopping at an intersection. On numerous occasions, the vehicle failed to stop until it was well into an intersection. Dealer would not repair unless "the abs light came on" which it never did. Owner removed the abs fuse and the vehicle stops normally with abs disabled. Owner investigation revealed that this is a common problem on the 1999 Silverado which requires nearly $1000 to repair, but gm will not cover the repair of these obviously defective abs systems. Dt.

When applying anti lock brakes, they failed. Also, power steering wouldn't work when coming to a stop and trying to turn. Took truck back numerous of times to the dealership, and they checked the truck, and said they couldn't find anything wrong with the truck. Called manufacturer about the the problem, and manufacturer called the service manager. Service manager told him to take his truck to another dealership. He traded a 2000, Chevrolet Silverado for a 2001 Chevrolet Silverado and still having the same problem. Tallked to several other people who had the same truck, and they were having similar problems. Had an accident on the the 2001 truck when the brakes wouldn't catch and hit an embankment, causing $1100. 00 worth of damage. No one was hurt. 2000 Chevrolet Silverado p/u, 4 w/d VIN#: 2gcek19v2y1119463; 22,826 miles; 2001 Chevrolet Silverado p//u 4 w/d VIN#:1gcek19tx1e155517; 50,000 miles.
