2006 GMC Sierra brakes problems

MY 2006 GMC HAS ONLY 29,000 MILES ON IT. I BOUGHT THE TRUCK IN OCTOBER 2009 WITH 16,000 MILES. I KEEP THE TRUCK CLEAN INSIDE AND OUT, TOP TO BOTTOM INCLUDING UNDER THE VEHICLE. PEOPLE COMMENT TO ME ALL THE TIME ON HOW NICE THE TRUCK LOOKS. BRAKE LINE LET GO IN YARD. PEDAL WENT TO THE FLOOR, NO BRAKES HAD TO HIT REVERSE THEN NEUTRAL AND THE EMERGENCY BRAKE. I HAD JUST RETURNED HOME FROM GOING UP TO…

TOTAL BRAKE FAILURE WHILE IN MOTION. CORRODED BRAKE LINE RUPTURED CAUSING IMMEDIATE LOSS OF ALL FLUID. HAD THIS HAPPENED 5 MINUTES EARLIER, I WOULD HAVE BEEN ON A FOUR LANE HIGHWAY IN BUMPER TO BUMPER CHRISTMAS TRAFFIC. AT 70 YEARS OLD I CAN ONLY IMAGINE HOW CATASTROPHIC AN ACCIDENT MY REFLEXES WOULD HAVE GENERATED. THE FLUID SPRAYED ON THE HOT ENGINE CREATING A CLOUD OF SMOKE. I WAS AFRAID THE TR…

2006 SIERRA DENALI WITH JUST OVER 75,000 MILES. WITH 1/2 BLOCK WARNING AND ONLY TRAVELING AT A SPEED OF 20MPH, I WAS UNABLE TO COME TO A COMPLETE STOP. THE BRAKE PEDAL WAS ALL OF THE WAY TO THE FLOOR WHEN I RAN INTO A VAN IN THE INTERSECTION. I FELT VERY LITTLE RESISTANCE FROM THE PEDAL AND THE ABS DEFINITELY DID NOT GO OFF. THERE WAS NO SNOW OR ICE ON THE ROAD SURFACE. HOWEVER AFTER TOWING TH…

TL*THE CONTACT OWNS A 2006 GMC SIERRA 1500. THE CONTACT STATED THAT THE MASTER CYLINDER FAILED ON HIS VEHICLE. WHILE DRIVING AT AN UNKNOWN SPEED, THE BRAKE PEDAL EXTENDED TO THE FLOOR AND THE VEHICLE FAILED TO STOP. THE CONTACT REAR ENDED ANOTHER VEHICLE. THERE WERE NO INJURIES. THE FRONT END, HOOD, AND GRILL WERE DAMAGED. THE VEHICLE WAS TOWED FROM THE SCENE AND RETURNED TO THE SHOP IT WAS …

ABS ACTIVATION AT LOW SPEEDS RESULTING IN INCREASE STOPPING DISTANCE. IT RESULTED ALMOST STRIKING A PEDESTRIAN IN A CROSSWALK. THIS HAD PREVIOUSLY BEEN REPAIRED AT MY OWN COST IN 2011 AND THE PROBLEM HAS AGAIN RETURNED. PREVIOUSLY GMC SIERRAS WERE RECALLED WITH THE SAME PROBLEM. RECALL NUMBER: 05V379000 RECALL DATE: 08/29/2005 COMPONENT: SERVICE BRAKES, HYDRAULIC:ANTILOCK PROBLEM SUMMARY…

I PURCHASED THE 2006 2500HD DIESEL PICKUP NEW. THE TRUCK HAS HAD POOR BRAKING SINCE NEW AND THE DEALER HAS ALWAYS SAID IT FUNCTIONS NORMALLY. I HAVE HAD THE DEALER DO ALL THE MAINTENANCE ON THE TRUCK OTHER THAN OIL AND FILTER CHANGES. THE UNDERCARRIAGE OF THE TRUCK INCLUDING ALL LINES, BRAKES ROTORS, HUBS HAS BEEN RUSTING SINCE NEW. THE UNDERSIDE OF THE TRUCK LOOKS LIKE A 20 YEAR OLD PLOW TRUCK. O…

HYDRAULIC BRAKE LINE RUST OUT RESULTS IN LOSS OF STOPPING ABILITY. THE "BLOW OUT" OCCURRED WHILE THE VEHICLE WAS STOPPED (I WAS VERY LUCKY!). UPON INSPECTION, SEVERAL OF THE HYDRAULIC LINES WERE RUSTED BADLY. I FELT THAT I HAD TO REPLACE THEM ALL (WITH STAINLESS STEEL LINES) TO PREVENT ANOTHER FAILURE WHICH COULD HAVE DIRE CONSEQUENCES. THE COST OF THE REPLACEMENT STAINLESS STEEL HYDRAULIC LIN…

ABS LIGHT KEEPS COMING ON WHILE DRIVING

WHEN BRAKING AT SLOW SPEEDS THE ANTI LOCK BRAKES APPEAR TO ENGAGE CAUSING THE PULSATING BRAKE IN THE PEDAL. THE TRUCK STOPPING DISTANCE IS INCREASED AND THE BRAKES DO NOT FULLY ENGAGE CAUSING THE TRUCK TO BUMP THE CURB. THE PROBLEM ALSO MAY HAPPEN AT HIGHER SPEEDS SUCH AS 25 MPH AND CORRECTS WHEN THE PEDAL IS DEPRESSED FULLY TO THE FLOOR CAUSING THE BRAKES TO FULLY ENGAGE (LOCK UP). THE PROBLEM…

WHILE DRIVING AT LOW SPEEDS, ABOUT 20 MPH OR LOWER, THE BRAKE PEDAL FADES TO THE FLOOR. THERE ARE NO LIGHTS OR CODES AND BRAKE FLUID AT THE PROPER LEVEL. THIS HAPPENS QUITE FREQUENTLY AND ANYWHERE.
