I HAVE A 1999 NEW BODY STYLE GMC SIERRA 3 DOOR TRUCK. I AM THE ONLY OWNER AND DRIVER OF THE VEHICLE. I ATTEMPTED TO USE THE EMERGENCY BRAKE IN 02/2002 AND IT DID NOT PREVENT THE TRUCK FROM ROLLING. I HAVE NEVER USED THE EMERGENCY BRAKE BEFORE TO EITHER STOP THE TRUCK OR HOLD IT IN PLACE AGAINST A LOAD. I TOOK THE TRUCK IN FOR OTHER UNRELATED FACTORY RECALL NOTICES. I HAD THE EMERGENCY BRAKE CHECKED. BOTH REAR BRAKE SHOE WHERE WORN COMPLETELY OUT AND THE DRUM ON ONE SIDE WAS BEYOND RECOVERY. I HAD TO BUY NEW SHOES AND REPLACE ONE ROTOR (APPROXIMATELY $450). AGAIN, I HAVE NEVER USED THE EMERGENCY BRAKE TO STOP THE VEHICLE OR HOLD IT IN PLACE AGAINST A LOAD. IT HAS NOT BEEN USED. THIS IS A SERIOUS SAFETY PROBLEM. I TALKED TO A GMC MECHANIC AND SEVERAL TRUCK OWNERS AND THEY HAVE HAD THE SAME PROBLEM. THE MECHANIC SAID HE HAS REPLACED SEVERAL EMERGENCY BRAKE SYSTEMS WITH THE OWNER STATING THE SAME THING I HAVE CONCERNING USAGE. SOME OF THESE VEHICLES HAD LESS THAN 30K MILES ON THEM. MY BROTHER HAS A 2000 CHEV. TRUCK AND THE SAME PROBLEM. A BRAKE SPECIALTY REPAIR CENTER TOLD HIM THE SAME THING THE GMC MECHANIC TOLD ME. THE EMERGENCY BRAKE SYSTEM HAS A SERIOUS DESIGN FLAW. IT WEARS OUT WITHOUT WARNING TO THE OWNER. I WROTE GMC CUSTOMER SERVICE AND THEY DISMISSED MY CONCERN WITHOUT FIRM EXPLANATION AFTER SEVERAL LETTERS. PLEASE INVESTIGATE THIS CONCERN. I DO NOT THINK THIS IS AN ISOLATED OCCURANCE.*AK

MY ABS BRAKE SYSTEM FAILED COMPLETELY. I CALLED GM WHO STILL HAVE NOT RETURNED MY CALLS. I CONTACTED THE GM DEALER HERE IN CHEYENNE. I WAS TOLD THIS IS A COMMON PROBLEM WITH THE 99 Z71; HOWEVER, THERE IS NO RECALL ON THIS ITEM. I WAS TOLD THEABS MOTOR HAS GONE OUT AND THE COST OF THE PART IS $700 WITH APPROXIMATELY $1500 IN LABOR. I CONTINUED TO QUESTION ON SINCE THIS GM DEALER IN CHEYENNE IS REPLACING THESE ABS BRAKE MOTORS SO OFTEN, ISN'T THIS CONSISTENT WITH A DEFECT? THIS IS A HAZARD HAVING YOUR ABS SYSTEM GO OUT IN THE ICE. THE GM DEALER TOLD ME TO CONTACT GM TO FIND OUT ABOUT REPLACING THE PART AT NO COST. AGAIN, I STILL HAVE NOT RECEIVED A CALL FROM THEM. MY QUESTION IS, IF THIS IS SUCH A COMMON PROBLEM IN THE 1999 SIERRA Z71 WHY HAS THIS NOT BEEN RECALLED? DO WE HAVE TO WAIT FOR A FATALITY TO OCCUR FIRST?*AK

THE ABS SYSTEM VIBRATES AT A LOW RATE AND VEHICLE WILL NOT SLOW DOWN WHEN APPLYING CONSTANT PRESSURE ON BRAKES. THERE APPEARS TO BE A 2 TO 3 SECOND DELAY BETWEEN THE TIME ABS TAKES OVER AND WHEN YOU HAVE COME CONTROL OVER THE BRAKING OF THE VEHICLE. THIS TIME ELAPSE CAUSES YOU TO USE OTHER MEANS FOR AVOIDING AN ACCIDENT SUCH AS VEERING TO THE LEFT OR RIGHT TO AVOID CONTACT DURING HEAVY BRAKING. THIS PROBLEM WILL ALSO OCCUR IF THE REAR DRIVETRAN LOSES CONTACT WITH THE ROAD SURFACE DURING LIGHT BRAKING. THE DRIVER HAS TO ALWAYS BE AWARE OF THE POSSIBILITY OF NOT BEING ABLE TO STOP TO BE ABLE TO AVOID AN ACCIDENT.
