AFTER DROPPING OFF A BOAT FOR WINTER STORAGE, I WAS LEAVING THE STORAGE LOCATION AND ATTEMPTED TO APPLY BRAKES AND THE PEDAL DROPPED TO THE FLOOR. I HAD TO TAKE A VERY SLOW ROUTE HOME AS THE BRAKE PEDAL CONTINUED TO DROP TO THE FLOOR ANYTIME THE BRAKES WERE APPLIED. IN A COUPLE OF INSTANCES WHEN THE BRAKE PEDAL WAS PRESSED HARD, THE ABS SYSTEM DID ACTIVATE. FINALLY HAD A CHANCE TO PULL THIS VEHICLE INTO MY GARAGE FOR EXAMINATION ON 11/8/13 AND FOUND THE BRAKE LINES UNDER THE DRIVERS' FLOORBOARD AT THE FRAME-RAIL EXTREMELY CORRODED TO THE POINT OF FAILURE OF ONE OF THE FIVE LINES. THE OTHERS ARE MOST CERTAINLY NOT FAR BEHIND. THIS VEHICLE IS MAINLY USED IN THE WINTER MONTHS. I AM GRATEFUL THAT THE PROBLEM SURFACED NOW BEFORE THE SNOWMOBILE SEASON WHEN I AM HAULING A 24 FOOT TRAILER WITH FOUR PASSENGERS AND FOUR SNOWMOBILES ON ROADS THAT ARE NOT IN THE BEST SHAPE TO BEGIN WITH. THIS COULD HAVE BEEN A VERY BAD SITUATION TO SAY THE LEAST! GM NEEDS TO FIX THIS ISSUE BEFORE SOMEONE IS SERIOUSLY INJURED OR WORSE - THESE OBVIOUSLY ARE NOT ISOLATED INCIDENTS. *** PLEASE NOTE THAT THERE HAS YET TO BE A SINGLE WARNING LAMP TO COME ON AFTER APPLYING THE BRAKES AT LEAST TWENTY FIVE TIMES - NO MIL, NO BRAKE, NOTHING! *** I WILL BE TAKING A COMPLETE SERIES OF PICTURES OF THE CONDITION OF THESE LINES BEFORE THE REPAIRS ARE PERFORMED IF THEY ARE NEEDED FOR THIS COMPLAINT. *TR

THE TRUCK WAS HOOKED TO A 25' GOOSENECK TRAILER LOADED WITH HAY. THE ENGINE WAS THE DURAMAX DIESEL WITH ALLISON TRANSMISSION. THE INTENT WAS TO HAUL HAY FROM EASTERN WASHINGTON TO WESTERN WASHINGTON. THE POWER STEERING PUMP BROKE A SHAFT INSIDE THE PUMP MAKING THE POWER STEERING UNUSABLE. AS IT TURNS OUT THE POWER STEERING PUMP ALSO SERVES AS THE POWER BRAKE ASSIST. AT A SPEED OF ABOUT 3 MPH, IT WAS ALL I COULD DO TO BRAKE THE TRUCK BUT WAS UNABLE TO TURN THE WHEELS. IT WAS VERY FORTUNATE THAT THIS HAPPENED IN THE FARMERS FIELD AND NOT ON THE HIGHWAY. IF I HAD BEEN DRIVING ON THE HIGHWAY WHEN THE PUMP QUIT WORKING, THE TRUCK WOULD HAVE GONE OFF OF THE ROADWAY, MOST LIKELY OVER A STEEP CLIFF BECAUSE I WOULD HAVE BEEN UNABLE TO STEER THE TRUCK OR STOP IT DUE TO THE SINGLE PUMP FAILURE. ADDITIONALLY, THE LOAD OF HAY WOULD HAVE CAUSED THE TRUCK TO PICK UP SPEED IF IT WAS GOING DOWN HILL. *TR

BROUGHT MY TRUCK IN FOR AN OIL CHANGE, THEY COME IN TO TELL ME, HEY, YOUR BRAKE LINE BLEW. I WENT DOWN TO CHECK IT OUT, THE LINES ARE PRETTY SEVERELY RUSTED, AND SURE ENOUGH BRAKE FLUID WAS LEAKING OUT ONE OF THEM. BRAKES GO TOTALLY TO THE FLOOR, ABSOLUTE MINIMAL BRAKE PEDAL PRESSURE. GOES RIGHT TO FLOOR EVERY TIME. IT DOESN'T COUNTERACT THE LOSS OF PRESSURE BY ALLOWING THE BACK BRAKE PRESSURE TO STILL WORK (THE FRONT LINE WAS THE LEAKER) LIKE GM SAYS THEY SHOULD. NO BRAKING AT ALL. HAD TO DRIVE IT HOME WITH E BRAKE, AND REPLACE ALL CORRODED BRAKE LINES. I'VE HEARD OF LOTS OF OTHERS HAVING THE SAME ISSUE, GM BRAKE LINES AREN'T UP TO PAR. *TR
WHEN I APPLIED PRESSURE TO THE BRAKE PEDAL, AS I BACKED UP IN MY DRIVEWAY, THE PEDAL WENT TO THE FLOORBOARDS. I STOPPED THE VEHICLE AND LOOKING UNDER THE TRUCK SAW A PUDDLE OF BRAKE FLUID.

WHEN I APPLIED PRESSURE TO THE BRAKE PEDAL, AS I BACKED UP IN MY DRIVEWAY, THE PEDAL WENT TO THE FLOORBOARDS. I STOPPED THE VEHICLE AND LOOKING UNDER THE TRUCK SAW A PUDDLE OF BRAKE FLUID. A CLOSER VISUAL INSPECTION REVEALED A LEAK IN THE BRAKE LINE FEEDING THE REAR WHEELS (NEXT TO THE FUEL TANK). I INSPECTED THE REMAINING LINES AND ALL APPEAR SERIOUSLY DETERIORATED. I WILL NEED TO HAVE ALL THE BRAKE LINES REPLACED. I FEEL FORTUNATE THAT I HAD NOT LEFT THE DRIVEWAY WHEN THIS BRAKE SYSTEM FAILURE OCCURRED. AND, JUST AS A SIDE NOTE, THE FRAME OF THE TRUCK, PARTICULARLY THE CROSS PIECES HOLDING THE SPARE TIRE AND BRACKET FOR THE SHOCK ABSORBER, HAVE RUSTED TO SUCH AN EXTENT THAT IT WILL HAVE TO REINFORCED/REPLACED. CORROSION THIS SEVERE COULD BE EXPECTED OF THE SHEET METAL, BUT NOT THE FRAME.
