1996 GMC Sierra

DT*: THE CONTACT STATED THE ABS ACTIVATED AT VARIOUS LOW SPEEDS AND THERE WERE INCREASED STOPPING DISTANCES. THERE IS A NHTSA RECALL, # 05V379000, REGARDING THE ANTILOCK BRAKES. THE VEHICLE HAS THE SAME PROBLEMS AS INDICATED IN THE RECALL; HOWEVER IT IS NOT INCLUDED IN THE RECALL DUE TO THE VIN. ALTHOUGH THESE PROBLEMS PERSISTED, THE VEHICLE WAS NOT SEEN BY A DEALER.

THE BRAKE LINE ABOVE THE GAS TANK RUSTED AND FAILED WHILE IT WAS BEING DRIVEN. THERE WAS NO FOREWARNING OF THIS AND AS IT WAS ABOVE THE GAS TANK, WOULD NOT HAVE BEEN NOTICED. THE GAS TANK HAD TO BE DROPPED AND THE BRAKE LINE REPLACED. THANK GOODNESS THE VEHICLE STOPPED BEFORE REARENDING THE VEHICLE IN FRONT OF ME AND THANK GOODNESS MY ONE YEAR OLD WASN'T IN THE VEHICLE AT THE TIME. OLD PART HAS BEEN RETAINED. REPAIR COST WAS $458.21.

TRAVELING ON DRY PAVEMENT AT ~ 30 MPH, SUDDEN STOP DUE TO TRAFFIC. BRAKE PEDAL INITIALLY HAD GOOD BRAKE THEN WENT TO THE FLOOR. ALL BRAKE LOST, COLLIDED INTO VEHICLE AHEAD OF ME AND PUSHED THEM INTO VEHICLE AHEAD OF THEM. VEHICLE STALLED DUE TO COLLISION, RESTARTED TRUCK AND ALL BRAKE OPERATION APPEARED TO BE GOOD. TOOK VEHICLE TO DEALER FOR ANALYSIS, CONTACTED GM CUSTOMER SUPPORT FILED COMPLAINT, DEALER INSPECTION SHOWED NO FAILURE OF ABS OR OTHER COMPONENTS. GM FIELD TECH WENT TO DEALER INSPECTION REPORT FOUND NO REASON FOR FAILURE COULD NOT DUPLICATE FAILURE. GM DENIES ANY RESPONSIBILITY OR SUGGESTIONS FOR REPAIR. *NM

"REFER TO PRIOR COMPLAINT- ID VQ-528687-YN-PDF" WHEN A WHEEL SKIDS A VERY,VERY,VERY SHORT DISTANCE WHILE BRAKING, ABS DOES NOT ENGAGE BUT LOCKS OUT CONVENTIONAL BRAKING! NO BRAKES, NO STOP. WHEN TOWING A 7000+ POUND LOAD IT GIVES YOU A VERY NEGATIVE THRILL. NO FIX FROM DEALER OR GMC, TRIED MANY, MANY TIMES. REMOVED 60 AMP ABS FUSE! TRUCK STOPS BUT IT IS NOT WHAT SHOULD BE DONE. I HAVE DRIVEN THE TRUCK 116000 MILES, 40000 WITH THE FUSE REMOVED. DO YOU HAVE ANY SUGGESTIONS OTHER THAN JUNKING IT, REPLACING THE FUSE AND KILLING MYSELF AND OTHERS, ETC. PLEASE ADVISE. IT APPEARS TO BE VERY SIMILAR TO THE ABS PROBLEM ON 1995 AND EARLIER TRUCKS THAT PROMPTED A (MFG?) RECALL BUT GMC DENIES IT. AT THAT TIME I SPOKE WITH THE REPRESENTATIVE THAT WAS INVESTIGATING THE ABS PROBLEM. EXPLAINED TO HIM WHAT I THOUGHT WOULD GIVE HIM THE BEST CHANCE TO DUPLICATE THE PROBLEM. I FOUND OUT LATER THAT IT WAS DETERMINED THAT THE ABS COMPUTER HAD A PROGRAMMING PROBLEM AND I BELIEVE GMC DEVELOPED A FIX FOR IT. WHAT CAN YOU DO TO HELP ME ON THIS?

CONSUMER STATED THAT SINCE HE PURCHASED VEHICLE HE HAD BRAKE PROBLEMS. ONCE HE COULD NOT STOP VEHICLE AND RAN INTO THE REAR OF ANOTHER VEHICLE, BUT NO DAMAGE WAS DONE. HE TOOK VEHICLE TO MIDAS AND HAD BRAKE REPAIRS DONE, BUT RIGHT WHEEL KEPT LOCKING UP. HE HAD A NEW DISC PUT ON THAT PARTICULAR WHEEL. BUT WHEN HE DROVE THE VEHICLE IT STILL LOCKED UP, AND BEGAN TO SMOKE. HE WAS AFRAID OF A VEHICLE FIRE. *AK

SEVERE SURFACE CORROSION ON REAR BRAKE LINE LED TO LINE BURSTING DURING AN EMERGENCY STOP TO AVOID A COLLISION. BURST OCCURED AT NINETY DEGREE BEND IN LINE BY BRACKET LEADING TO THE FLEXIBLE LINE TO REAR AXLE. SURFACE CORROSION APPEARS ALONG BRAKE LINES AT OTHER PLACES. I THINK IT IS UNUSUAL THAT THE BRAKE LINES ON A SEVEN YEAR OLD VEHICLE WOULD EXHIBIT SUCH SEVERE CORROSION. UNLESS YOU WERE LOOKING FOR THIS YOU WOULD NOT NORMALLY SEE IT SINCE THE LINE RUNS INSIDE THE FRAME RAIL.*AK
