Problems with 1999 Chevrolet Silverado 1500 SERVICE BRAKES, HYDRAULIC

Abs module failure. *tr

Anti lock brake problems; at slower speeds when applying break, brake does not hold.*ak

At about 40,000 miles my abs motor under the drivers seat came on and would not turn off. contacted dealer, they said this was a common problem and the part needed to fix it cost $900. after investigating the problem i found there were thousands of 99 chevy 1500 owners with the exact problem.

Parked my 1999 chevrolet k pickup at a store and just before i turned the engine off, the abs light came on. when the ignition was off, there was a grinding noise from under the vehicle. apparently the abs module was still running. i crawled under the vehicle and unplugged it. when i took it to my gm mechanic, he told me that the ebcm shorted out and apparently happens frequently to this model. it cost me $781 for the part plus labor of $202.50. i was unimpressed, especially to find out that there has been so much problem with this and that there is no recall for it. can you help? isn't this a safety issue? my vehicle only has 50496 miles on it.*ak

Problems with abs system on 1999 chevrolet k1500.*mr before the consumer turned off the engine the abs light illuminated on the dash. when the ignition was off the consumer heard a grinding noise which originated under the vehicle. the consumer crawled under the vehicle and unplugged the abs and the noise stopped. the vehicle was taken to the dealer where it was determined that the ebcm shorted out. the consumer was told that this is a common problem with this model chevrolet. *nm

On the approx. date listed i had a problem with my abs. system running non stop. when i approached a local dealer about this issue, i was told it would be a few thousand dollars to fix or i could just pull the fuse and ignore the lights that would be on so this is what i did. i was recently notified that this problem could now be fixed for much less ($1500). *nm

March,2004 shut off truck and heard sound (like a small electric motor running) coming from under truck. unplugged electrical connection to avoid running battery down. called my mechanic and he knew right away what was wrong, he said he has seen quite a few of the 1999 pickups with the same condition. as a friend he looked at it no charge. said it would be around $650.00 to fix. called chevy dealer and they told me gm would pay half. i laughed and said that's not good enough. they also wanted $79.00 diagnostic fee. what a joke. i wrote a letter to gm they did not respond. i called on the phone and got all the way to the secretary of the chevrolet division and she would not put me through to him. i'm now driving with standard brakes but my child drive my truck from time to time and feel like i'm not providing him with a safe vehicle and i dont have the money to fix it. *nm

Dt*: the contact stated after parking the vehicle, a noise like a small electric motor running was heard. the underside of the vehicle was inspected by the contact. the plug to the abs antilock brake pump was disconnected. a service dealer was contacted and offered to diagnose and replace the pump at half the cost. the manufacturer was notified and made the same offer. updated 10/25/2006

At speeds under 7 miles per hour when the brakes are applied the anti-lock system engages and will not allow the brakes to work (no brakes whats so ever and the truck keeps rolling without any stopping effects at all). *ak

[1] brakeing seemed to be erratic so i went to a dealer to have it checked out.upon inspection it was found that the rear brakeing system was rusted to the point of a critical condition.[2]life threatening. [3]dealer replaced rotors,disks&pads on both rear wheels.

Consumer applied the brakes and the brake pedal went to the floor. took vehicle to the dealer for analysis. the mechanic could not resolve the problem. *ak

Dt: the contact is having a problem with the abs. it is engaging at low speeds at 5 mph. this has been a continuing problem for the past two years. he pulled the abs fuse to get the abs deactivated. the vehicle is running correctly now that the fuse has been removed. he contacted gm, and was informed that there were no recalls on this vehicle. also, he states that the straps on the tailgate are not holding correctly. *ak

Abs motor control unit failure, after seeing many complaints on the web i am reporting it here. abs warning light came on and pump motor started running. even when turning off the motor, the unit still runs. abs failure. had to pull fuse to stop, now driving without abs and abs and brake warning lights are on. $1000 - $1500 to repair problem, will most likely drive without abs for a long time. *la

Abs computer failed in my 1999 chevrolet k1500 silverado pickup. the module makes a continuous noise like a small engine running even with the key removed from the ignition. the only way to stop the noise is to disconnect the battery or remove the abs 60 amp fuse. dealer informs me the part costs $875.00 in checking with used parts shops i found this part is in very high demand -- much greater than they can supply. one used parts dealer told me they had 18 requests this year alone. the chevrolet dealer hesitatingly admitted they replace lots of these. with the fuse removed the vehicle is drivable but without the abs function. the dash board does have indicators constantly lit for brakes and abs. *jb

The abs module failed, which caused the vehicle to experience extended stopping distance.*jb

Constant noise from under drivers side ,had gm dealer diagnose problem ($75),was told electronic brake control module had internal short. ext. warranty would not cover the $900.00 expense,contacted gm customer assistance who said they could not help with problem,showed no concern over the safety of having the abs system working, dealer tech. advised to pull fuse. am know without abs brakes. feel gm should take care of this safety issue. *nm

Contact states: the brakes failed and the consumer ran into a vehicle. the rotors rusted so badly that brakes were not being applied. when he contacted gm. they told him to take it to the dealer, and the dealer replaced the hub assembly. they wouldn't pay for the brakes or the damage done to his truck. just the hub assembly.*ak the ignition system was replaced. *jb

Abs light come on. abs motor began to buzz and would not stop when the engine was shut off. i had to take the fuse out that was for the abs brakes. the brake light and abs light stay on the dash. i recently had valid break issues and i was not able to tell due to the staying on continually. *nlm

My 1999 chevrolet 1500 z71 has had numerous abs failures. a few very close calls. the dealer or mechanic haven't heard of a recall. i understand that the abs module is telling the system that one wheel is slowing down as if a skid erroneously which activates the abs taking the driver out of the equation. sombodys going to die. please forward any info to the e-mail address i listed . thank you. *ak

While driving 30mph brakes operated poorly, resulting in extended stopping distance, also brake pads wore out at 4000 miles.*ak

The abs pump wont shut off when i turn off my truck, causing a dead battery. the pump went bad 3 weeks after the warranty expired. dealer told me it would be around $1000 to fix or i could pull the fuse. every person ive talked to with a 99 silverado has had the exact same problem.

The abs sensor failure caused the front caliper and the rotor to fail which was replaced. *yh

Abs pump went out, luckly i had an extended warranty and only had to pay $100.00 instead of $800.00. also many other trucks in the area with same problem. had klunking noise in rear end carried to two different dealer ships and could not find anything. sounded like transmission was playing catch up with rearend. three months after warranty goes out it does the same thing and bust the gears in transmission. motor sounds like it is knocking when you first crank it up. the dealerships around are quick to sell you a car but will not stand behind you when there are problems. this will probally be my last chevy!!! *jb

The abs modual on my 1999 k1500 chevyrolet truck has gone bad. the pump stays on at all times, unless you pull out the fuse for the abs. by disconnecting the fuse, the abs brakes are disabled for the truck. this also leaves the abs light and brake light in the dash on. the replacement for this part is around $1000. this appears to be a fairly common problem on this model truck.my father is haveing the same luck with his 1999 k2500. note that the dealer recommended fix, short of replacing the unit, is pulling out the fuse. *ak
