1994 Chevrolet S10

THE BRAKE PEDAL WILL GO TO THE FLOOR WHEN THE ABS SYSTEM RESPONDS TO A BUMP IN THE ROAD, RESULTING IN EXTENDED STOPPING DISTANCES. THE BRAKE PEDAL NEEDS TO BE PUMPED SEVERAL TIMES UNTIL A FIRM PEDAL IS ACHIEVED. THIS OCCURS ONLY INTERMITTENTLY, SO IS DIFFICULT TO TROUBLESHOOT. THE 'RECALL' WORK FOR THE ABS WAS PERFORMED YEARS AGO. THIS PROBLEM HAS OCCURED BOTH BEFORE AND AFTER THE ABS WORK WAS PERFORMED.*AK

CONSUMER WAS DRIVING APPROX 30MPH AND BEGAN BRAKING. ONCE REACHED APPROXIMATELY 10MPH, BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. CONSUMER HAD TO CONTINOUSLY PUMP BRAKES FOR BRAKING ABILITY TO RETURN. VEHICLE CHECKED BY DEALER, WHO REPLACED MASTER CYLINDER. ON 7/19/01 INCIDENT OCCURRED AGAIN. VEHICLE CHECKED BY DEALER, WHO COULD NOT FIND A CAUSE. *AK *JB

IN SITUATIONS WHERE EMERGENCY STOPS ARE NEEDED ON ROAD SURFACES THAT ARE COVERED WITH GRAVEL, WET, OR OTHERWISE TRACTION CHALLENGING ENVIRONMENT, THE BRAKES ARE NOT RELIABLE. THE DESIGN OF THE BRAKE SYSTEM OF THIS CLASS VEHICLE IS FAULTY, AND PRODUCES UNRELIABLE PREFORMANCE AT TIMES WHEN ONE WOULD EXPECT RELIABLE AND DEPENDABLE PERFORMANCE. SINCE BUYING THIS TRUCK I HAVE BEEN INVOLVED IN 3 REAR END COLLISIONS IN WHICH THE TRUCK DID NOT STOP UNTIL IT FOUND WHATEVER WAS IN FRONT OF ME. IN ALL 3 CASES IT HAS BEEN ANOTHER CAR PRODUCING, 2 POSSIBLY 3, WHIPLASH CLAIMS PLUS VECHICLE DAMAGE CLAIMS. UNTIL BUYING THIS VEHICLE I NEVER HAD A REAR END ACCIDENT. ON 7/7/2002, ON A WET BUT LEVEL PRAVEMENT AS I APPROACHED AN INTERSECTION WITH A TRAFFIC LIGHT THAT WAS RED FOR THE DIRECTION I WAS GOING. I BEGAN TO SLOW DOWN AS I APPROACHED THE CAR IN FRONT OF ME. THE BRAKE LIGHTS ON THE CAR IN FRONT OF ME WENT OUT AND IT APPEAR THE CAR WAS MOVING FORWARD. WHEN THE BRAKE LIGHTS SUDDENLY CAME BACK ON, I HIT MY BRAKE PEDDLE HARD AND FIRM. INTIALLY THERE WAS SOME BRAKING SENSATION AN A "WHIRRRR-ING" SOUND BUT I KEPT GOING FORWARD UNTIL I HIT THE CAR IN FRONT ME. WHILE DAMAGE TO MY TRUCK WAS MINIMAL, ABOUT $900, THE REAR OF THE 2001 NISSAN ALTIMA THAT I HIT, WAS CONSIDERABLE, FORTUNATELY THE DRIVER SAYS SHE WAS NOT HURT BUT I WOULD NOT BE SURPRISED IF A WHIPLASH CLAIM IS FILED. THE NEXT DAY I TOOK THE TRUCK INTO THE NEAREST CHEVROLET DEALER TO CHECK THE CONDITION OF THE BRAKES AND TO DOUBLE CHECK THAT THE RECALL CAMPAIGN WORK HAD BEEN DONE. THE BRAKES WERE INSPECTED, ROAD TESTED AND DECLARED TO BE IN PROPER CONDITION AND "FUNCTION AS DESIGNED". THE KEY HERE IS THE PHRASE FUNCTION AS DESIGNED. WHAT IS NOT SAID IS THAT THE DESIGN OF THIS BRAKE SYSTEM ALLOWS FOR AN EXTENDED STOPPING DISTANCE OF UNPREDICTABLE LENGTH OR CONTROL OF THE DRIVER, UNDER THE EXACT CIRCUMSTANCES OF MY COLLISIONS. NEITHER CHEVROLET OR GM GIVE A WARNING IN THE OWNER'S MANUAL OR BY OTHER MEANS.*AK

SINCE ABS CAMPAIGN #C99046 VEHICLE RECALL SERVICE JULY 7, 2000 TO REPLACE ABS PART # 8880026 MODULE KIT 4.720 I HAVE HAD THREE LOSS OF BRAKES IN EMERGENCY STOP/ACCIDENT AVOIDANCE SITUATION RESULTING IN DAMAGES TO FRONTAL AREA OF MY VEHICLE ALL 3 TIME. AND THE LAST TWO TIMES REAR ENDING OTHER PERSON'S VEHICLES. EVER SINCE THIS RECALLED MODULE WAS CHANGED IN LOW SPEED SUDD STOP OR ACCIDENT AVOIDANCE MANEUVERS WHILE HITTING THE BRAKE PEDAL THE ABS UNIT COMES ON WITH A PEDAL PUMPING PULSATION BUT NEVER SLOWS OR STOPS THE TRUCK. I HAVE ALSO HAD BOTH FRONT SEAT TRACKS BROKEN BY THE IMPACT TO IMPAIRING REAR SEAT PASSENGER ENTRY AND EXIT. I HAVE HAD THE BRAKES REDONE CONTINOUSLY AND FILED CLAIM WITH G.M. LAST TIME REQUESTING ENGINEERING INVESTIGATION TO NO AVAIL. I HAVE FOUND THAT THIS MODEL ABS REAR BRAKES ARE NOT AUTO ADJUSTING AFTER TWO PRIOR ACCIDENTS TRYING TO GET TH BRAKES WORKING CORRECTLY. I HAD HAD NO FOLLOWUP BY NHTSA REGARDING MY LAST COMPLAINT BY MADE BY A TTY/RELAY CALL AS I AM DEAF. MY INSURANC HAS GONE OUT OF SIGHT BECAUSE OF ACCIDENT CLAIM FILINGS TO FIX THIS TRUCK AND NEVER ONCE DID THE INSURANCE COMPANIES INCLUDE TH BRAKE REPAIRS IN THEIR REPORTS. THE TRUCK BRAKES FINE UNDER ALL NOPRMAL DRIVING CONDITIONS INCLUDING HIGH SPEED THRUWAY ACCIDENT AVOIDANCE STOPS. ITS JUST THE LOW SPEED ON DRY ROADS WITH VERY WARM NEAR 90 DEGREE TEMPERATURE DAYS ON ASPHALT THIS HAPPENS AND THERE IS NEVER A BRAKING SKID MARK OR WHEEL LOCK UP AT ANY ACCIDENT SITE. I WAS ADVISED THAT THE RECALL MODULE REPLACEMENT WAS TO RESOLVE A "NORTHERN" WINTERTIME ICY CONDITION STOPPING PROBLEM. THE TRUCK HAS NEVER BEEN DRIVEN IN NORTHERN ICY CLIMATES AND THE TRUCK HAS ALWAYS HAD EXPENSIVE OVERSIZED SPECIAL HIGH PERFORMANCE TIRES/WHEELS/SUSPENSION COMPONENTS TO ENHANCE BRAKING AND HANDLING. WITH THIS RECALL MODULE CHANGE THE BRAKE FLUID ALSO GETS BLACK AND CONTAMINATED FASTER. I WANT TO UNLOAD THIS VEHICLE BUT AM AFRAID A PERSON UNFAMILIAR COULD GET HURT OR HURT SOMEONE. HELP!*AK
