Brake Antilock Wheel Speed Sensor Problems of Chevrolet Silverado - part 2

The contact stated when putting pressure on the brake pedal the vehicle did not stop properly. There was extended stopping distance. The abs system activates, and it took longer for the vehicle to stop. The contact took the vehicle to a local mechanic shop and had the vehicle repaired. The mechanic replaced the left and right front speed sensors. There was manufacturer's recall 05068 but the contact's state was not included in the recall.

The contact stated the dealer diagnosed the problem as the abs signal dropping out at low speeds. This vehicle was showing the same symptoms as indicated in the recall. The delaer told her on 11-05-29005 this vehicle was not involved on 11-05-05 the wheel speed sensors had to be replaced at the contact's expense.

When applying the brakes, the pedal kicks up and the vehicle is difficult to stop. The stopping distance has at least doubled. I found that the anti-lock brake speed sensor quit working with 37000 miles on the truck. I unplugged the sensor and the brakes are working fine (without anti lock brakes).

The abs comes on at low speed when it shouldn't, resulting in extending stopping distance. Dealer miss diagnosed the problem as the left front hub. Replacing both front hubs and wheel speed sensors which fixed the problem.

About a year in half ago the anti lock brakes starting acting up, when it was wet and preparing to stop the anti lock brakes would engage and the truck would not stop. Code was left front sensor. This was replaced. Did not correct the problem. Had the right front sensor replaced, did not correct the problem. The fuse was then unplugged just so I would have brakes. Currently, in vermont truck was due for inspection in June, and it will not pass inspection, with or without the anti lock brakes. Spoke with elmore at gm in portland office, and he advised to take vehicle to gm dealer and have a diagnostic test done. Dealer cleaned both front speed sensors but did not guarantee it would solve the problem.

I am experiencing undesired application of the anti-lock brake system on my 2002 Chevrolet Silverado pick up truck due to faulty wheel hub speed sensors. It started out as a once in a while thing a couple months ago and is now an almost routine occurance on almost every braking. When the abs applies, the stopping distance is almost doubled. This occurs at speeds below 10mph, which is when you are usually closing the range on whatever you're trying to stop for. Aside from having it checked over by a local Chevrolet dealer, nothing has been done to correct the failure. The cost estimate has ranged from $300. 00 up to over $1,000. 00. I was told the problem was corrosion related due to being kept outside and driven on dirt roads, etc. The truck was purchased from my uncle who drove it on paved roads, kept it in a heated garage, and it has seen only occasional exposure to road salt. It is only in the last year that is has been parked outdoors on a regular basis. I have not done the repairs as I am going to persue it with gm to pay for them since this is a very common problem and is no way related to anything I've done, as well as being out of my budget if the cost becomes excessive.

2001 Chevrolet Silverado experiencing problems with the anti-lock brake system. The consumer stated the abs began to engage on dry pavement while slowing between speeds of 5 mph and stopping. At first it was occasional, but then the brakes began to engage consistently on dry pavement. The consumer took the vehicle to a mechanic where corrosion was discovered on the driver side front wheel speed sensor. The mechanic recommended removing, lubricating and replacing both front wheel speed sensors. The mechanic stated it was a common problem with the pickup's due to the design of the part and the conditions which the vehicle are driven; snow and highway salt.

The vehicle is a 2000 Chevrolet Silverado pick-up truck. The abs is coming on unexpectedly when the consumer applies the brakes. Several times when this occurred it caused the brakes not to work properly and at other times it caused them to fail. This problem has caused the consumer to almost hit another vehicle and a building on separate occasions. She has taken it to the dealership which they told her that the problem was the abs senor needed to be cleaned. They removed and cleaned both front wheel speed sensors. Because of some kind of build up on the sensor. When the consumer had this fixed the dealership broke the brake pads and rotors trying to get to the problem. They replaced these parts at the consumers expense. The problem has not come back since they cleaned the sensor. This is the only know problem with the vehicle at this time.

Dt contact states in March, 2005, when brakes were applied it seemed as if the anti lock brake system was in. When the brakes were pushed, the vehicle did not stop right away, but did eventually stop. The contact took the vehicle to a service dealer, they stated that the vehicle computer was showing there was nothing wrong. The service mechanic suggested taking the vehicle to the dealership where the vehicle was purchased. They informed the contact that rotors needed to be replaced due to rust, replaced left front wheel speed sensor, cleaned front and rear speed sensor ground. This did help the problem. The dealership stated that the rotors needed to be replaced.

The contact owns a 2002 Chevrolet Silverado z71. While driving approximately 15 mph in normal conditions, the vehicle lunged without warning when the brake pedal was depressed. The vehicle was taken to an authorized dealer for inspection and they stated that the failure was related to the speed sensor. The speed sensor system was replaced in the vehicle. The failure recurred on a separate occasion. The contact received a recall notice and the vehicle was repaired for the recall defect; however, the failure recurred. The recall remedy has not corrected the failure. The vehicle has not been repaired. The VIN, NHTSA campaign id number, and failure mileage were unknown. The current mileage was 94,000. Updated 03/04/09. Updated 03/06/09.

Brake pedal became very hard, truck became hard to stop under 5 miles per hour. The problem occured more often,once for every three stops. The truck was taken to the dealer for repairs. The antilock brakes were found to be faulty. A speed sensor was replaced in each front wheel. Cost of repairs was $400.

Traveling at slow speeds, the brakes would not work (anti-lock activating) causing long stopping distance or had to stomp brake peddle several times to get vehicle to stop. No major accidents but second time I ran over sidewalk I took car to service center (not dealer) and they disconnected anti-lock brakes and have not had any further trouble. Mechanic said the brake sensors (speed sensors?) would need to be replaced.

: the contact stated the abs activates below 10 mph. There is a NHTSA recall, # 05v379000, regarding the anti-lock brakes. The vehicle has the same problems as indicated in the recall; however, it is not included in the recall due to the VIN. Upon inspection of the vehicle,it was discovered both abs speed sensors were faulty. Updated 03/03/06.

Dt: 2002 chevy Silverado. When the consumer applied the brakes, the abs activated. The abs activated on dry roads as well. Sometimes when this happened the abs popped the brake pedal up and the consumer would not be able to stop the truck. Sometimes the consumer had to place the gear into park just to stop. The vehicle was taken to the dealer, who said it was a wheel speed sensor issue. The vehicle has not been repaired.

Contact states: abs on 2001 Chevrolet, Silverado pickup truck. Abs kicked in at low speed. Progressed to where consumer had no brakes at low speed. He had them repaired. The left front hub and speed sensor was replaced.

Upon braking to a stop when 5 mph is reached the abs system falsely activates and prevents the truck from coming to a complete stop. This problem has resulted in one low speed collision (<5 mph) and numerous times I have hit parking barriers. I am told the solution to the problem is to have the front wheel speed sensors removed from the hub/bearing assembly and cleaned. Also, gm has a TSB out on this problem and transportation canada has issued a safety recall for this problem.

Abs initates on dry pavement as I decelerate from about 6 mph to about 3mph. This happens approximately 50% of every stop. I have not had any incidents, as I am the only driver, and allow extra distance. After talking with 4 CO-workers who have/had the same problem, I pulled the abs fuse and have not completed a repair yet. My extended warranty provider claims it is a service claim, which is not covered under warranty. Dealership says it's a common problem with this model, not covered under the extended warranty. Says it's rust build up under the speed sensor, and needs to be cleaned & reseated. I read about this investigation on my company website, and decided to register my problem to help the research.

While driving at a low speed the brake pedal went completely to the floor. Contacted the dealer. However the problem recurred. Dealer stated the sensor hub assembly has to be replaced. The dealer replaced both front wheel speed sensors and cleaned the hubs.

1/2) low speed manuevering in parking lot or pulling up to a stop sign or red light situatiuons on various road conditions; first became an issue after snow/freezing weather conditions with no earlier warning signs, but continued to occur occasionally even on dry pavement; brake failure / inadvertant abs activation upon extemely low speed causing vehicle to coast further and overall increased stopping distance when this failure would occur 3) dealer replaced left front hub and wheel speed sensor assembly as they had found the sensor was providing erratic readings (in warranty service--no charge).

Failure of service brakes which resulted in a crash (low speed). Caused by corrosion of speed sensors. Repaired by dealer (cleaning of speed sensors). Dealer repair manager explained that the problem has occurred in past and another similar incident occurred a few days after this one, involving another Chevrolet truck. Dealer further related that the manufacturer is aware of the problem however has only issued a bulletin on how to repair at owners cost (approx. $400. 00 without replacement parts, only labor).

There were no unusual events leading up to the failure of the anti-lock braking system in my truck. The system would fail to operate properly at approximately 5 mph when coming to a stop. The failure is that the system engages unnecessarily at low speeds, causing the vehicle not to stop when desired. It would happen several times daily, and the only crash I did not avoid was into a chain link fence, which did not cause damage. However, there were several near misses. The corrective action that I took was to remove the fuse for the anti-lock brakes. The corrective action that my dealer suggested was to spend $500 replacing the front wheel speed sensors. He said that this is a common occurrence on the Chevrolet Silverado, and that my problem would only get worse. Gm has issued a TSB on this issue, but not safety recall. I feel that since I have lurched into busy intersections, lurched forward in crosswalks, and come close to crashing into other vehicles while parking, this should be regarded as a safety issue.

The abs brakes locked and the pedal went to the floor at low speeds between 3-10 mph. Also, the brakes would not function properly at high speeds. This resulted in extended stopping distance. The consumer replaced the front wheel bearings and wheel speed sensors; this did not correct the problem. The consumer did not refer vehicle to a dealer, but took vehicle to a certified mechanic, who did not known how to remedy the problem. The consumer was experiencing the same problem with his gm truck. A recall was issued. However, this vehicle was not included in the recall due to the model year although the exact same brake system was on this vehicle.

Abs brakes engage each time I come to a slow stop( I. E. Pulling up to a stop sign or red light) extending my stopping distance. Dealer states that the abs speed sensors and front hubs must be replaced but cannot tell me what is wrong. The abs warning light does not come on although according to the dealer( kelly Chevrolet, butler, PA) the system is malfunctioning.

Dt : about 6 months ago going slowyly brakes were applied hard but they wouldnt work, and vehicle went through the garage. Dealer reported that the wheel speed sensors were corroded. The problem was repaired with a new wheel on the left side front. The right front was cleaned. The problem was returning. When approaching a stop sign the abs was heard, and resulted in extended stopping distance. This occurred in all conditions. The abs warning light did not come on.

2000 chevy Silverado z-71, 4wd, v-8 extended cab 31,000 miles. I purchased the vehicle used on June 24, 2004. In September, 2004 I noticed that the abs brake system would activate as I slowed (< 10 mph) to a stop. This issue began intermittantly but worsened as I continued to drive the vehicle. By Jan, 2005, the abs would activate every time I applied the brakes at slow speeds (< 10 mph). No trouble lights came on. I did not have any accidents with this issue but had one very close call in a parking lot. This incident caused m to investigate and fix the problem. In late January, I had a gm dealer investigate the issue and they recommended replacing the left front hub assembly. Given the high price the dealer was going to charge for the replacement part and the labor, I elected to purchase a replacement front hub assembly from a local auto parts store (autozone). I replaced the left front hub assembly per the vehicle's service manual directions. And the problem went away. The hub I removed was heavily corroded with signs that the seal on the inboard side of the hub was corroded with a portion of the excluder lips missing. I still have the hub assembly that was removed from the vehicle and would be glad to provide it for teardown inspection. In addition, I am a degreed mechanical engineer that works for a leading axle and driveshaft manufacturer and would be glad to discuss this serious safety issue further. I believe that seal failed and this allowed debris / corrosion to enter the hub assembly which then subsequently caused a signal interuption between the tone whee and speed sensor. Thus, the abs system believed that the left front hub was not rotating and caused the abs system to activate. My issue is very much like the issue described in the may 27, 2005 issue of the detroit free pess titled "gm truck owners insist brakes are a problem".

Intermittent loss of braking power. The brake pedal went to the floor, and vehicle experienced extended stopping distance. Dealer was notified. Dealer informed consumer that wheel speed sensor needed to be replaced. The vehicle crashed into a wall resulting in front end damage.

Abs system intermittently engages at low speed (@5mph). While pulling into a parking space, the abs engaged and I almost hit the car in the next slot. Also, while parking in front a a restaraunt, the abs engaged and I almost drove into the lobby. I've had the speed sensors replaced at about 60k milesand today (73k miles)the hubs are being replaced.

The contact stated there was a recall on the abs brakes. Has contacted the manufacturer, and they will replace the abs speed sensors, but they will not replace the rotors. The contact was having a problem with the rotors. They were corroded. He had the rotors turned and put back on vehicle with new pads. The abs speed sensors were still not working correctly. Updated 12/27/05.

Contact has no brakes between 0-10 mph. Brakes do work at other speeds. The vehicle wa seen by a local dealer who wanted to charge for repairs. The caller saw a recall for canadian vehicles in regard to what may be this same problem. The problem was front wheel speed sensor corrosion. There has been no accident although there were three near misses. The first incident was a year ago.

While applying the brake pedal the brakes failed. This caused consumer's vehicle to collide with another vehicle. Consumer took vehicle to dealer for inspection, and mechanic determined that speed control sensor needed to be replaced and he replaced it, however the problem recurred. The dealer has replaced the rotors due to rust, the pads, brake bleeder screws due to rust, the right front wheel speed sensor and the left front wheel speed sensor.

I purchased the vehicle with just over 36000 miles and have used it as a daily-driver. The abs began to activate while maneuvering at low speeds. Problem has occurred more often than I can count. Has lead to the vehicle running up onto curbs/sidewalks. One occasion has caused me to hit another vehicle. Dealership told me, after examining the vehicle, it was defective speed sensors. (they didn't really inspect it. The speed sensors were replaced earlier that week) ended up replacing entire front assemblies. I was told that the parts wore out. (funny, was told the plastic speed sensors wore out the metal surrounding them. And they showed no wear) I have the original speed sensors.

The contact owns a 1999 Chevrolet Silverado. While driving approximately 10 mph, the contact depressed the brake pedal and the vehicle failed to slow down. He crashed into the trash cans and the vehicle sustained minor damages. There were no injuries. The vehicle was taken to an independent mechanic that stated the failure was related to the rusting of the anti-lock sensor. The vehicle was repaired. Recently, the failure recurred. The authorized dealer advised the contact to pay for a diagnostic test. The contact was concerned of the safety risk involved with this malfunction. The failure mileage was 45,000 and current mileage was 85,000. Updated 07/29/08 the consumer stated the problem was due to a rusty speed sensor and the repair that the dealer performed was only a temporary fix. Updated 08/07/08.

Complete brake failure while pulling into a parking space at 2 mph, resulting in a accident. The consumer read there was a common problem with the anti-lock brake system activating at low speeds, if any surface rust or debris build up was on the wheel speed sensor mounting surface.

While driving at any speed and applying the brakes pedal went all the way to the floor, resulting in extended stopping distance. This vehicle was unsafe to drive. However, dealer replaced the speed sensor, but problem recurred.

1999 chevy, abs activates at low speeds ever since I bought the truck used in NY 2 years ago. When the problem started it was hit and miss, but now it happens all the time at low braking speeds. I have replaced 1 low speed sensor that did not help, so I removed the abs fuse. Gm said that my problem fits the recall #05068, but I was not the original owner and live in nc that I was not going to be included in the recall. I feel that this recall should include all vehicles that have been titled in the "salt belt" states regardless of where they are now and who owns them.
