AS I APPROACHED A TRAFFIC LIGHT AT 30 MPH AND ATTEMPTED TO STOP, THE BRAKE PEDAL WENT RIGHT TO THE FLOOR WITH NO WARNING. I HAD TO VIGOROUSLY PUMP IT SEVERAL TIME TO COME TO A STOP AND WAS LUCKY I WAS GOING SLOWLY AND THERE WERE NO STOPPED CARS AHEAD OF ME. NO WARNING LIGHTS APPEARED ON THE DASH AND STILL DO NOT IF YOU START THE TRUCK. I WAS CLOSE TO HOME AND CAREFULLY MANAGED TO GET TO MY DRIVEWAY. A LARGE PUDDLE OF BRAKE FLUID DRIPPED FROM THE DRIVER SIDE BENEATH THE DOOR. WHEN I INSPECTED IT FROM BELOW, I FOUND THE BRAKE LINES SEVERELY CORRODED WHERE CLIPPED TO THE FRAME AND ONE HAD BURST THROUGH, CAUSING THE LEAK AND LOSS OF STOPPING ABILITY. *TR
BRAKE LINES UNDER HOOD AT DRIVERS SIDE RUSTED HOLE IN LINE CAUSED BRAKE FAILURE. *TR

I WAS ON MY WAY TO THE AUTOPARTS STORE FOR AN OIL FILTER FOR MY OTHER VEHICLE WHEN I CAME UPON A LIGHT AT A BUSY INTERSECTION. AS THE LIGHT CHANGED TO YELLOW I HIT MY BRAKES AND THE PEDAL WENT RIGHT TO THE FLOOR. I WAS DOING NO MORE THAN 30 AT THIS TIME. THERE WAS NO WAY THAT I COULD STOP, I DRIFTED THROUGH THE INTERSECTION AND WAS ABLE TO DRIFT TO SAFETY. I WAS LUCKY - ANOTHER CAR WAS ALSO ABOUT TO TURN LEFT IN FRONT OF ME AS I WAS DRIFTING THROUGH THE INTERSECTION, HE STOPPED SO AN ACCIDENT WAS AVOIDED. HAD THE VEHICLE TOWED AND HAD TO HAVE ALL BRAKE LINES REPLACED. ALL WERE RUSTED AND PITTED. PAID NEARLY $900.00 TO HAVE STAINLESS STEEL BRAKE LINES INSTALLED. THESE (STAINLESS STEEL BRAKE LINES) SHOULD HAVE BEEN INSTALLED BY GM AT THE FACTORY. MANUFACTURERS ALL USE STAINLESS STEEL FOR EXHAUST, WHY NOT FOR BRAKE LINES - SEEMS A BIT MORE IMPORTANT TO USE STAINLESS BRAKE LINES. WHAT IS THE COST DIFFERENTIAL BETWEEN CHEAP STEEL AND STAINLESS - A FEW EXTRA DOLLARS SPENT IN MANUFACTURING COULD SAVE SOMEONE'S LIFE. *TR

BRAKES FAILED DUE TO BURST LINE TO REAR AXLE; LITTLE OR NO STOPPING POWER FROM FRONT BRAKES; EMERGENCY BRAKE WORKED FOR A FEW MINUTES BUT NO LONGER AFTER COUPLE OF MILES TO MY DRIVEWAY. DISASSEMBLY REVEALED E-BRAKE PADS HAD CRUMBLED AWAY INSIDE REAR ROTORS; AND ALL 5 BRAKE LINES COMING OUT OF ABS UNIT WILL NEED TO BE REPLACED, NOT JUST REAR. FYI I HAVE OWNED IN EXCESS OF 20 G.M. TRUCKS, BUT NONE EVER AS BAD AS THIS ON BRAKE LINES. DAUGHTER IN TRUCK WITH ME- THIS COULD HAVE TURNED OUT VERY BADLY. TRUCK UNUSABLE UNTIL ALL LINES ARE FIXED- VERY DIFFICULT DUE TO POSITIONING OF LINES ( I HAVE DONE MANY BRAKE LINES- ON MUCH OLDER TRUCKS). THANKS... *TR

I TOOK MY 2002 CHEVY SILVERADO 1500 IN TO GET INSPECTED. IT FAILED DUE TO NO PARKING/EMERGENCY BRAKES. I HAVE NEVER USED MY PARKING BRAKE, NEVER BEEN IN THE WHERE IT WAS NEEDED. I FIRST NOTICED AFTER REMOVING WHEEL THAT EVERYTHING IS RUSTED BEYOND WHAT I THINK IT SHOULD BE AT THIS POINT, THE SPLASH SHIELDS ARE ALMOST COMPLETELY GONE. I REMOVED THE DRUM AND BRAKE SHOES AND NOTICED THAT ON BOTH SETS OF SHOES, LEFT AND RIGHT, THE PADS OF THE SHOES WERE NOT REALLY WORN, BUT THE ACTUAL LINING THAT THE SHOES ARE ATTACHED TO WERE WORN AT THE VERY BOTTOM ON THE DRIVERS SIDE AND THE VERY TOP ON THE PASSENGER SIDE, BOTH WHERE THERE ARE NO PADS. I FOLLOWED THE DIRECTIONS THAT CAME WITH THE NEW SHOES, REPLACED EVERYTHING, AND STILL NO BRAKES. I THEN BOUGHT A NEW CABLE AND SWAPPED IT OUT, THINKING THE CABLE MAY BE STRETCHED. STILL NO BRAKES. I REMOVED THE WHEEL AND DRUM ONCE AGAIN AND HAD SOMEONE DEPRESS THE PARKING BRAKE. I NOTICED THE ACTUATOR WORKING, SO I REASSEMBLED EVERYTHING, AND STILL NO BRAKES. I THEN CONTACTED GM CUSTOMER SERVICE TO SEE IF THERE WERE ANY RECALLS FOR THIS PROBLEM, I WAS TOLD THAT THERE WAS NOT. I WAS TOLD THAT I CAN TAKE MY TRUCK TO A CERTIFIED CHEVY DEALER FOR THEM TO DIAGNOSE THE PROBLEM, AT MY EXPENSE, BEING THAT I HAVEN'T BEEN ABLE TO FIND GAINFUL EMPLOYMENT IN OVER 3 1/2 YEARS, I CAN NOT AFFORD THIS. I WAS TOLD THERE IS NOTHING FURTHER THAT CAN BE DONE TO HELP ME. I HAVE LESS THAN 2 WEEKS FOR MY TRUCK TO PASS INSPECTION, IF NOT, THEN I MUST PAY FINES AND COSTS WHEN I DO REREGISTER MY VEHICLE. HOW DO I GET MY VEHICLE TO PASS INSPECTION WHEN THERE IS OBVIOUSLY A DEFECT IN THEIR DESIGN. I'M HITTING A BRICK WALL EVERYWHERE I TURN. WITH ALL THE COMPLAINTS AND PROBLEMS THAT I SEE BEING POSTED ONLINE, HOW COULD THERE NOT BE A RECALL. WHAT HAS TO HAPPEN FOR THEM TO TAKE RESPONSIBILITY FOR THIS PROBLEM. *TR

STEEL BRAKE LINE RUSTED THROUGH AT REAR OF TRUCK NEAR DRIVER SIDE WHEEL WELL. ALL OTHER STEEL BRAKE AND FUEL LINES IN TRUCK HEAVILY RUSTED AND ALSO NEAR BLOW OUT POINT. *TR WHEN REAR LINE FAILED, BRAKE PEDAL WENT TO THE FLOOR AND STOPPING DISTANCE DOUBLED. I WAS PULLING A 3,000LBS BOAT AT THE TIME. THE BRAKE WARNING LAMP DID NOT ILLUMINATE. BRAKE WARNING LAMP CAME ON ONLY AFTER APPROX 10 MILES OF NO REAR BRAKE AVAILABILITY. I AM CURRENTLY TAKING PREVENTIVE MEASURES AND REPLACING ALL STEEL LINES IN TRUCK. OLD LINES AVAILABLE FOR INSPECTION IF YOU ACT QUICKLY.

Status: closed (inferred from source dates) · Parking Brake
ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
