2006 Chevrolet Silverado 1500

AS I COME TO A STOP, THE BRAKE PEDAL PULSATES FROM ABS ACTIVATION INCREASING BRAKING TIME AND DISTANCE. THE GROUND IS DRY WHILE THIS HAPPENS. AFTER A WHILE THE AND LIGHT COMES ON. WAS TOLD BY A DEALER MECHANIC IT WAS A BAD ABS SENSOR AND TO REPLACE HUB. I DID AND NOW, TWO YEARS LATER, IT IS HAPPENING AGAIN. NOW I'M BEING TOLD IT IS A PROBLEM WITH ELEMENTS IN MY AREA, BEING IN A SNOWBELT STATE, GETTING INTO WHEEL SPEED SENSOR AND BLOCKING SIGNAL. SAME EXACT SYMPTOMS AS LAST TIME, DIFFERENT DIAGNOSIS. NEITHER TIME DID THEY PLUG INTO MY TRUCK FOR CODES. BOTH TIMES, I HAVE TO OPEN MY WALLET FOR FAULTY PRODUCTS.

I HAVE A HOME IN THE HILLS OF WEST VIRGINIA AND HAD JUST RETURNED FROM TOWN AFTER DRIVING UP AND DOWN LOCAL MOUNTAIN ROADS. I PARKED IN THE DRIVEWAY WITHOUT INCIDENT. WHEN I STARTED THE TRUCK TO MOVE IT IN DRIVEWAY AND PRESSED ON THE BRAKE PEDDLE, THE PEDDLE WENT COMPLETELY TO THE FLOOR AND I WAS TOTALLY WITHOUT BRAKES. LUCKILY, I WAS ON A FLAT SURFACE AND USED MY EMERGENCY BRAKE TO STOP VEHICLE. WHEN I STEPPED ON THE BRAKES AGAIN, I NOTICED A STREAM OF BRAKE FLUID SQUIRTING OUT FROM THE AREA UNDER THE DRIVER SIDE DOOR. UPON FURTHER INVESTIGATION I REALIZED THAT ONE OF THE BRAKE LINES ALONG THE FRAME HAD FAILED DUE TO CORROSION. ONLY ONE OF THE 4 BRAKE LINES HAD FAILED, HOWEVER, THE ENTIRE BRAKING SYSTEM WAS RENDERED COMPLETELY INOPERABLE. ABSOLUTELY NO REDUNDANT BRAKING AVAILABLE, EXCEPT FOR THE EMERGENCY BRAKE. IF THIS HAPPENED WHILE DRIVE ON THE HIGHWAY OR DOWN THE MOUNTAIN, IT COULD HAVE BEEN CATASTROPHIC. THE TRUCK HAS NO VISIBLE BODY OR FRAME CORROSION. HOW COULD THE THE SAFETY-CRITICAL BRAKE LINES CORRODE WHEN THE REST OF THE VEHICLE IS IN GOOD SHAPE RUST-WISE? SEEMS GM HAS USED SUB-STANDARD BRAKE LINES IN THE VEHICLE. I HAVE RESEARCHED THIS ISSUE AND IT IS A WELL-DOCUMENTED PROBLEM THAT GM KNOWS ABOUT AND SHOULD BE REQUIRED TO ADDRESS.

TL* THE CONTACT OWNS A 2006 CHEVROLET SILVERADO 1500. WHILE DRIVING APPROXIMATELY 35 MPH, THE BRAKE PEDAL WAS DEPRESSED, BUT THE VEHICLE HESITATED TO STOP. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE MECHANIC REPLACED THE BRAKE SYSTEM BUT THE FAILURE RECURRED. THE VIN WAS UNAVAILABLE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 110,000.

WHEN SLOWING DOWN TO STOP,APP 5 TO 10 MPH,BEFORE STOP.BRAKE PEDEL WILL SOFT AND PLUSE LIKE BRAKES WENT AWAY BUT STOPING YOU.ITS FEELS LIKE YOU LOST YOUR BRAKES.ITS BEEN STEATY APP 9 OUT OF 10 TIMES. HAD VEHICLE CHECK OUT SEVERAL PLACES FOR BAKES ISSUES,NEW ROTORS ,PADS ,DRUMS,AND SHOES .PLUG IN COMPUTER NO CODES ON BRAKES OR ABS SYSTEM.ITS CAN BE SCARY WHEN DRIVING TRYING TO STOP.

TRAVELED TO STORE ABOUT FOUR BLOCKS AWAY FROM MY RESIDENCE. UPON RETURNING, I NOTICED MY BRAKES BARELY WORKING WHILE GOING DOWNHILL ON STREET. I HAD TO DOWNSHIFT AND USE EMERGENCY BRAKE TO GET TO BOTTOM OF HILL. AT BOTTOM OF HILL IS MY DRIVEWAY. I WAS ABLE TO ENTER MY DRIVEWAY AND PARK. I COULD SEE A LIQUID DRIPPING RAPIDLY -- BRAKE FLUID-- UNDER THE TRUCK ABOUT THE MIDDLE OF THE DRIVERS SIDE DOOR. I OPENED THE HOOD AND CHECKED THE BRAKE FLUID LEVEL, ONLY A SMALL AMOUNT LEFT. WITHIN FIVE MINUTES THE REST OF THE BRAKE FLUID HAD DRAINED OUT WITH GRAVITY. THANKFULLY NO ONE WAS IN FRONT OF ME OR CROSSING THE STREET. NOTE: THERE WAS NO INDICATION ON DASH LIT PRIOR TO THIS HAPPENING. BRAKING LOSS HAPPENED FIRST. SEEMS LIKE BRAKE LINE JUST SPLIT/BURST.

LEAVING MY DRIVE WAY MY BRAKE PEDDLE WENT ALL THE WAY TO THE FLOOR. I HAD TO USE EMERGENCY BRAKE TO STOP TRUCK. AFTER CHECKING FOR PROBLEM I FOUND THAT THE METAL BRAKE LINE FROM THE MASTER CYLINDER TO THE BRAKES HAD RUSTED THROUGH IN THE ENGINE AREA AND BRAKE FLUID WAS BEING SPRAYED ON THE MANIFOLD. (IF ENGINE WAS HOTTER THEIR COULD HAVE BEEN A FIRE.) TRUCK IS SITTING IN MY DRIVEWAY STILL NOT FIXED.

APPROACHING A STOP SIGN I APPLIED THE BRAKES AND THE PEDAL WENT TO THE FLOOR. UPON EXAMINATION I FOUND THE BRAKE FLUID WAS LEAKING FROM A RUSTED LINE AT THE READ RIGHT OF THE TRUCK WHERE THE BRAKE LINE FROM THE FRONT OF THE VEHICLE CONNECTS TO THE RUBBER HOSE THAT FEEDS BOTH SIDES OF THE REAR BRAKES. THE REST OF THE LINES LOOK GREAT BUT THAT MAIN FEED IS RUSTED AND FAILED. THIS HAS NEVER HAPPENED TO ME IN ALL YEARS OWNING VEHICLES.

TL* THE CONTACT OWNS A 2006 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 55 MPH, THE BRAKE PEDAL WAS DEPRESSED AND THERE WAS AN INCREASED IN STOPPING DISTANCE. THE CONTACT DISCOVERED THAT THE BRAKE LINES RUSTED AND CORRODED CAUSING THE BRAKE FLUID TO LEAK FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHO DIAGNOSED THAT THE BRAKE LINES NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 26,000.
