1999 Chevrolet Silverado brakes complaints
Page 24 of 35: complaints 671 to 700 of 1,003, newest first, as owners wrote them.
Approximately one week ago I began noticing problems on rough surfaces with my anti-lock brakes. Whenever the brakes were applied on a rough surface the anti-lock brakes actuated but didn't seem to be stopping the car. I attributed the problem to be simply a function of the rough surface combined with the rainy conditions at the time. Yesterday morning when I started my vehicle the ABS light came on and I immediately noticed a loud clicking noise which continued even after turning off the ignition. I had to remove the 60 amp fuse for the brake system to stop the pump from actuating. I took the vehicle to the dealer and was informed that the electronic module which operates the system had shorted out. This same problem has been experienced by 6 other people I work with here at eglin afb.
While driving at low speed and without warning anti-lock brake system was inoperable. Dealer has disconnected the system until further service.
When engine is turned off ABS pump continues to run. Consumer has to disconnect wire for pump to stop. *ak
After starting engine consumer noticed ABS pump kept running.
Abs failed with vehicle in motion. Abs motor/pump ran with the vehicle and shut it down. Dealer replaced the ABS module to correct the fault. Dealer personnel commented that this was a rather prevalent failure mode on this model truck. Dealer also stated that the replacement ABS module was an improved design, and the had not experienced any failures of the improved modules. Chevrolet customer assistance refuses to acknowledge that a problem exists and will take no action to correct this deficiency. *ts ***dimsii ivoq entry posted after 12-12-02 cut over to artemis***763173
Consumer states at 50,000 the ABS light stays on while driving. Cause unknown. Dealer notified.*ak
After turning off vehicle they can still hear ABS engaging. Cause unknown. Dealer notified.
Abs pump motor continuously runs ,causing ABS system to fail, resulting in extended stopping distance. Abs and regular brake light illumiinates if the vehicle stops quickly showing a system malfunction. Please describe more information.
The ebcm (electronic brake control module) failed, leaving me with no anit-lock brakes. I believe this is due to the fact that they mounted this electrical system underneath the truck (exposed to all elements) rather than underneath the hood. In fact, chevrolet must believe the same thing, because they changed the design in 2000 (they now put this component underneath the hood). I know this has happened to many people (see discussion thread "silverado ABS module failure" on http://www.4x4review.com/discussions/chevy/). Furthermore, chevrolet wants to charge almost $1800 to fix this ($711 for just the part, but special tools are required to calibrate it). I think this cost is prohibitive (almost 10% cost of the vehicle) to many people, causing them to neglect this repair and go without ABS. The central point of this complaint is that this is a design flaw and chevrolet refuses to provide any cost assistance.*ak.water can also get into the hydr, pump and brake down the brake fuel,causing brake failure.
Abs motor will continue to run even after the vehicle is shut off. Contacted dealer, and the dealer is not willing to do anything.
When shutting off engine ABS pump keeps running, braking distance is normal.*ak.
The ABS module started running when it did not need to be and would not shut off. I contacted service department at molle chevrolet in blue springs, mo, and they knew exactly what the problem was because they had seen the same thing several times before. They wanted around $1000 to fix it. I feel like gm needs to recall this component if it is failing with such high frequencies. I don't feel as safe driving without ABS especially in a pickup which is light on the rear end and can slide easily in an emergency situation.
Abs motor will not turn off after the consumer takes the keys out of ignition.
While traveling at 30 MPH, consumer pressed brakes to avoid hitting a deer and vehicle started to slide. Consumer states ABS locked up. Driver and passenger sustained injuries, passenger sustained injury to vocal cord due to seatbelt failure.
Abs motor was still running while vehicle was parked in the garage. Dealer contacted. Feel free to provide any further information.
Consumer stopped vehicle, when he went to restart the engine, consumer noticed the motor running, after investigating consumer discovered the ABS brake module was still running after the engine was shut down and the key turned off, consumer removed the fuse for the ABS to get the motor on the brake module to stop running.
Brakes locked up while the consumer was driving 25-35 MPH, causing vehicle to crash into a tree. Contacted dealer who was not willing to do anything. *ak. Consumer has documentation that the ABS module malfunctioned, there were 2 injuries, consumer does not believe that the recall on the seat belts was not repaired.
Control module failed, pump runs off of which makes ABS inoperable. Please provide any further information.
Emergency brake had to be replaced, would no longer hold when applied.*ak also, the rear brakes were worn out. The rear rotors could not be turned since it had crumbled. The driver door was replaced and the door panel was reinstalled.
While at dealership for repair work mechanic determined that rear rotors were crumbling and needed to be replaced, drums and lining as well.*ak the emergency brake was not working. The rear brakes were corroded and worn out. The rear brake pads and both rear rotors were replaced. The brake shoes on both sides were replaced. There was a squeaking noise in the front end when the vehicle goes over bumps. The driver door panel failed and was reinstalled, also the arm rest for the bucket seat pops off constantly, seat belts lock up after being replaced twice under recall, the steering joint was repaired, also when consumer steps on the gas, the truck does not move for a few seconds, the rear window was replaced, due to leaking, and the engine hesitates.
Abs computer malfunctioned causing loss of anti lock braking feature. Abs motor continues to operate after vehicle is shut down. Dealer disconnected fuse to deactivate the motor.
I already filled out a vehicle owner's questionnaire to send through the mail with my signature to authorize the federal safety agency to provide a copy of the report to the manufacturer. Reference no. 8008990. I included a copy of a recall notice on the 2000 chevrolet silverado 1500. The recall states: light duty pickup trucks equipped with 4-wheel disc brakes. Some of these vehicles have an ABS motor containing an out-of-specification spring clip. This clip could allow the motor bearing to become misaligned. If misalignment occurs, eventually the ABS would be non-functional. The base brakes would remain functional, but the dynamic rear proportioning system (drp), which optimizes front to rear brake balance, would become inoperative. This is the same malfunction my 1999 silverado 1500 has. The ABS systems are identicle in the 1999 and 2000 silverado. The replacement part number is the same for a 1999 and a 2000. I don't believe this is a coincidence, that this part has failed in my 1999, when in fact this is the same part in the 2000's that were recalled.
Abs was not working properly due malfunction of control unit. Dealer contacted.
Vehicle could be turned off and ABS motor would remain on. Repair shop notified, and informed consumer that ABS pump and module needed to be replaced. Dealer notifed. Feel free to provide any further information.
