1992 Chevrolet Suburban SERVICE BRAKES, HYDRAULIC

CONSUMER STATES WHILE DRIVING VEHICLE ON WET SURFACE THE BRAKE PEDAL WILL GO TO THE FLOOR CAUSING THE VEHICLE TO HAVE EXTENDED STOPPING DISTANCE. *NLM

ABS BRAKING SYSTEM IS DEFECTIVE. HOWEVER, BRAKING SYSTEM WORKS. SO WHEN TRAVELING IN SNOW OR ICE AND MAKING A SUDDEN STOP ABS SYTEM TAKES LONGER. *AK

WHILE DRIVING ON HIGHWAY ABS BRAKES KICKED IN ON DRY PAVEMENT UNEXPECTEDLY, AND EXTENDED STOPPING DISTANCE 50 PERCENT. CONTACT DEALER.*AK

THIS VEHICLE HAS A TREMENDOUSLY LONG STOPPING DISTANCE, ESPECIALLY IN THE WET. ONE DEALER SAYS THERE IS NOTHING WRONG; THE OTHER SAYS TO TRY A NEW ANTILOCK UNIT. THEY SAY IT MIGHT HELP BUT IF IT DOESN'T MAKE ANY DIFFERENCE IT IS NON-RETURNABLE. IT WILL COST @ $1000 JUST TO TRIAL AND ERROR A FIX FOR A SERIOUS SAFETY DEFECT. *AK

ABS BRAKING SYSTEM MALFUNCTIONED, CAUSING EXTENDED STOPPING DISTANCE WHICH RESULTED IN A CRASH. THE BRAKE MANUFACTURER IS AWARE OF THE PROBLEM BUT HAS YET TO FIX IT. *AK *ML

ON ANY SLICK ROAD SURFACES AT SPEED OF 10 MILES PER HOUR , WHEN THE BRAKES WERE APPLIED TO COME TO A COMPLETE STOP AT STOPSIGN. THE ANTILOCK BRAKE SYSTEM KICKED IN. THE ANTILOCK BRAKE LIGHT AND THE BRAKE LIGHT TURN ON IN THE CONTROL PANEL. THE ANTILOCK BRAKE SYSTEM IS SUPPOSED TO READJUST ITSELF AUTOMATICALLY IN A FEW SECONDS AFTER IT HAS BEEN DEPLOYED. BUT MY VEHICLE DOES NOT DO THIS. THIS IS THE SECOND INCIDENT THAT THE ANTILOCK BRAKE SYSTEM HAS KICKED IN WITHIN A SIX MONTHS PERIOD SINCE THE VEHICLE WAS PURCHASED. THE FIRST INCIDENT INVOLVED A COMPLETELY DIFFERENT SCENARIO. THE FIRST TIME THE ROADS WERE SLICK AND THE VEHICLE WAS BEING DRIVEN ON THE HIGHWAY AT ABOUT 55 MPH. ANOTHER VEHICLE WAS ENTERING THE HIGHWAY AT A HIGH RATE OF SPEED, DESPITE THE SLICK ROAD CONDITIONS. THIS VEHICLE HIT A SLICK SPOT ON THE HIGHWAY AND SLIDE COMPLETE ACROSS THE THREE LANE HIGHWAY, INWHICH I WAS TRAVELING ON THE FARTHEST LANE. THERE WERE ABOUT 4 OTHER CARS THAT HAD TO SLAM ON THEIR BRAKES AND BASICALLY COME TO A COMPLETE STOP IN ORDER TO AVOID THE VEHICLE THAT WAS SKIDDING THROUGH THE HIGHWAY. MY ANTILOCK BRAKES KICKED IN WITH A LOUD THUG. AND THE ANTILOCK LIGHT AND BRAKE LIGHT CAME ON TOO. BUT IT NEVER READJUSTED ITSELF AFTER THIS INCIDENT. THE VEHICLE HAD TO BE TAKEN INTO REPAIR TO RESET THE ABS. THE FIRST TIME HAPPENED IN JULY 1999 AND WAS REPAIRED IN EARLY AUGUST. THIS SECOND INCIDENT DID NOT WARRENT THE ABS TO KICK IN. I BELIEVE THAT THE ABS ARE OVERLY SENSITIVE AND NEED TO BE REPROGRAMED. I HEARD ON A NEWS REPORT THAT THE CHEVROLET SUBURBAN WAS BEING RECALLED FOR ITS FAULTY ABS BRAKES FROM 1999 THROUGH 1992. HOWEVER, I HAVE BEEN UNABLE TO CONFIRM THAT THE 1992 CHEVROLET SUBURBAN IS BEING RECALLED FOR THIS PROBLEM. THE DEALERSHIP THAT I CALLED ABOUT REPAIRS SAID THE RECALL WAS FOR VEHICLES STARTING IN 1994, NOT 1992. I WOULD LIKE TO GET THIS RESOLVED . PLEASE LET ME KNOW THE RESULTS. THANK YOU.

WHEN THE BRAKES WERE APPLIED PEDAL WENT TO THE FLOOR, RESULTING IN EXTENDED STOPPING DISTANCE, CAUSING A COLLISION. DEALER HAS BEEN NOTIFIED. *AK

BRAKES SLIP DURING A NORMAL STOPPING, CAUSING EXTENDED STOPPING DISTANCE.DEALER HAS YET TO BE CONTACTED. *AK

NO SUMMARY

THE FIRST BRAKE FAILURE OCCURRED ON MARCH 30, 1999 AT THE INTERSECTION OF AL 150 AND I-459 IN HOOVER AL. I TRIED TO STOP AT THE LIGHT BUT THE SUBURBAN JUST WOULD NOT STOP. THE ANTI LOCK MECHANISM DID NOT ACTIVATE AND THERE WAS NO SLIDING OR SKIDDING. I RAN INTO THE BACK OF THE CAR IN FRONT OF ME AT ABOUT 5 MPH. THERE WAS RAIN PRESENT, BUT IT WAS LIGHT RAIN ITH NO WATER STANDING ON THE ROAD. THE SECOND OCCASION WAS IN HOUSTON TX ON MAY 28, 1999. MY DAUGHTER WAS DRIVING THE SUBURBAN ON THE SAM HOUSTON TOLL ROAD WHEN SHE WENT TO CHANGE LANES. SHE DISCOVERED THAT SOMEONE WAS OVERTAKING HER FROM BEHIND AT A HIGH RATE OF SPEED IN THE LANE THAT SHE WANTED TO BE IN. SHE PULLED THE WHEEL IN THE OPPOSITE DIRECTION, SAW SOMEONE IN THE ADJACENT LANE, PULLED THE WHEEL IN THE OPPOSITE DIRECTION AND APPLIED THE BRAKES, HARD. THE SUBURBAN'S REAR WHEELS LOCKED, AND THE SUBURBAN MADE A 180 DEGREE TURN IN THE MIDDLE OF THE ROAD, AND EXITTED THE ROADWAY BACKWARD AT ABOUT 20 MPH STRIKING A CONCRETE BARRIER. I HAVE SPENT ABOUT $1000 MAKING THE SUBURBAN DRIVABLE, AND I HAVE NOT GOTTEN INTO THE BODY WORK YET. I FEEL THAT BOTH OCCURANCES HAVE BEEN CAUSED AT LEAST IN PART BY FAILURE OF THE FOUR WHEEL ANTI LOCK BRAKE SYSTEM. THE RIGHT REAR WHEEL THREW THE TREAD SIX DAYS LATER ON THE WAY HOME. I DON'T THINK IT WAS DESIGNED TO GO SIDEWAYS.( DOT NUMBER: AN11LX1127 TIRE SIZE: LT24575R16 )

ON TWO OCCASIONS THE CONSUMER HAS SLAMMED ON BRAKES ABRUPTLY, THE BRAKE PEDAL WENT TO THE FLOOR AND THE ANTI LOCK BRAKES FAILED, DEALER CHECKED BUT SAID THEY LOOKED FINE. NLM

EA95026, INTERMITTENTLY, THE ABS BRAKING SYSTEM MALFUNCTIONED, CAUSING BRAKE PEDAL TO THE FLOOR, CAUSING EXTENDED STOPPING DISTANCE AND VIBRATION, WHICH MAY RESULT IN A CRASH. DEALER REPLACED PARTS IN THE BRAKING SYSTEM. PROBLEM IS STILL OCCURRING. PLEASE PROVIDE FURTHER INFORMATION. *AK

ABS DOES NOT STOP MY SUBURBAN WHEN SYSTEM ACTIVATED. THE VEHICLE TAKES A LOT LONGER TO STOP. I HAVE TALKED TO THE DEALER AND SEVERAL BRAKE SHOPS AND THEY CLAIM THIS PHENOMENON IS NORMAL. THIS PROBLEM HAS CAUSED 4 NEAR MISSES AND ONE ACCIDENT. I JUST WANT TO KNOW HOW TO GET IT CORRECTED BEFORE WE GET IN A SERIOUS ACCIDENT. *AK

ONGOING / INTERMITTENT PROBLEM WITH ABS SYSTEM ACTIVATING BY ITSELF, AND CAUSING BRAKE SYSTEM TO FAIL. DEALER INSPECTED VEHICLE AND INFORMED CONSUMER THAT THE COST OF REPAIRS WOULD BE AT CONSUMER'S EXPENSE OF APPROXIMATELY $1300.00. SEEKING HELP FROM NHTSA IN THIS MATTER. *AK

FAILED ABS IMPACTS BRAKING ACTION - INCREASED STOPPING DISTANCE, SOFT PEDAL. SETS TROUBLE CODE 63. DEFINITE SAFETY HAZARD. 4WD ABS INSTALLED ON 2WD VEHICLE AT FACTORY. UNDERSTAND THAT RECALL TO REPLACE CORRECT ABS MAY BE PENDING.

WHEN THE BRAKES ARE APPLIED INTERMITTENTLY A GRINDING NOISE IS HEARD, WHICH RESULTS IN EXTENDED STOPPING DISTANCE. BRAKES HAVE BEEN WORKED ON BY PRIVATE MECHANIC. MANUFACTURER HAS BEEN NOTIFIED. *AK *YC

ABS SYSTEM FAILS TO OPERATE RESULTING IN BRAKE PEDAL GOING TO FLOOR, COMPLETE LOSS OF BRAKING, AND A LOUD SQUEALING NOISE FROM THE UNIT. IN PRIOR INCIDENTS TO 2-12-99, VEHICLE HAS BEEN PUT UP ON CURB AND HOMEOWNER'S FRONT LAWN TO AVOID REAR END COLLISIONS. ON 2-12-99 REARENDED A PICKUP TRUCK THAT STOPPED SUDDENLY IN FRONT OF ME. HAD AT LEAST 50 FEET OF STOPPING DISTANCE. WHEN CHEVROLET DEALER WAS QUESTIONED ABOUT SUBURBAN ABS PROBLEM, OWNER WAS TOLD PROBLEM DOES NOT EXIST. SYSTEM IS SUPPOSED TO ACT LIKE IT DOES AND SQUEAL IS NORMAL. UNLESS ABS LIGHT COMES ON, IT IS NOT VEHICLE ERROR. MASTER CYLINDER HAS BEEN REPLACED ON VEHICLE, BUT DANGEROUS SITUATION CONTINUES TO PERSIST.

CONSUMER HAS BEEN EXPERIENCING PROBLEMS WITH ANITLOCK BRAKES. WHEN DRIVER APPLIED BRAKES DURING INCLEMENT WEATHER, VEHICLE SKIDDED. ON DRY PAVEMENT, AND/OR DURING LOW SPEEDS, IT IS DIFFICULT TO STOP. THE MANUFACTURER HAS YET TO BE CONTACTED. *AK *ML

WE HAVE HAD AN ONGOING PROBLEM WITH THE ANTI LOCK BRAKES MAKING A LOUD GROANING SOUND. THIS TYPICALLY OCCURS RIGHT AFTER WE START THE ENGINE AND THEN SEEMS TO GO AWAY. IT WILL ALSO OCCUR WHEN WE GO OVER A BUMP WITH THE BRAKES ENGAGED. I REPORTED THIS TO THE DEALER(S) WHEN WE FIRST GOT THE VEHICLE AND THEY COULD NOT FIND ANYTHING WRONG. ON JAN 15, 1999 I WAS FOLLOWING A CAR WHO STOPPED AT A YELLOW SIGNAL LIGHT. WHEN I APPLIED THE BRAKES, THERE WAS A LOUD "GROAN" AND I BELIEVE THE PEDAL WENT TO FLOOR. I HAD ADEQUATE ROOM TO STOP, BUT THE BRAKES SEEMED TO JUST NOT WORK PROPERLY. WHEN I WENT OUT THIS MORNING TO CHECKTHE BRAKES, THEY FELT SPONGY AND THEN FINALLY GOT A NORMAL FEEL AGAIN. I BELIEVE THAT THERE IS A PROBLEM WITH THE ANTI-LOCK BRAKES ON THIS VEHICLE. FORTUNATELY THE ACCIDENT WAS RELATIVELY MINOR; HOWEVER, I BELIEVE THAT GM SHOULD FIX BOTH MY VEHICLES BRAKES, AND TAKE CARE OF THE DAMAGE ON THE OTHER CAR. I WILL BE OUT OF TOWN UNTIL THE 26TH OF JANUARY.

WHEN BRAKES ARE APPLIED IN EMERGENCY SITUATION THE PEDAL IS HARD. THE BRAKES REACT AND THEN RELEASE, CAUSING THE VEHICLE TO KEEP ON ROLLING. DEALER HAS BEEN CONTACTED. *AK *ML
