SERVICE BRAKES, HYDRAULIC
MY TRUCK WAS PARKED. I STARTED MY TRUCK. I APPLIED THE BRAKE TO PUT MY TRUCK IN GEAR. THE BRAKE PEDAL WENT COMPLETELY DOWN TO THE FLOOR. I INSPECTED UNDER MY TRUCK, AND THERE WAS A PUDDLE OF BRAKE FLUID UNDER THE DRIVER'S SIDE AREA ON THE CEMENT. I SAW THAT ALL THE BRAKE LINES CONNECTED TO THE ABS ELECTRO-HYDRAULIC CONTROL UNIT ARE SEVERELY RUSTED, AND ONE OF THEM WAS LEAKING SEVERELY. I HAD MY TRUCK TOWED HOME. THERE WAS NO WARNING LIGHT ON THE DASH THAT WAS BLINKING TO TELL ME I THAT I WAS HAVING A PROBLEM WITH MY BRAKES. THEY WERE WORKING FINE PRIOR TO THIS FAILURE. I WILL DOCUMENT THE CONDITION OF THE BRAKE LINES WITH A PICTURE AND BRAKE MECHANIC WITNESSES BEFORE ANY REPAIRS. I AM IN THE PROCESS OF LOCATING A BRAKE REPAIR BUSINESS. *TR

SERVICE BRAKES, HYDRAULIC
I PURCHASED A 2003 GMC SIERRA (USED) -CHECKED IT OUT AFTER A MECHANIC TOLD ME ABOUT BRAKE LINE PROBLEMS. MY TRUCK HAS EXTREMELY BAD RUST ON THE PORTIONS OF LINE I CAN SEE (LOOKS LIKE CLAMSHELLS OPENING). I HAVE DONE SOME RESEARCH AND HAVE FOUND YOU HAVE AN OPEN INVESTIGATION ON THIS PROBLEM. I OWN 1966 AND 1980 VEHICLES WITH ORIGINAL TUBING IN BETTER CONDITION. MY QUESTION TO YOU IS SIMPLE. A RECALL WAS ISSUED FOR AFTERMARKET FUEL FILTERS THAT MAY LEAK AND CATCH ON FIRE IF YOU PARK OVER AN IGNITION SOURCE BUT NO RECALL ON A MAJOR ISSUE CONCERNING BRAKES. I AM PRETTY SURE MORE PEOPLE USE THEIR BRAKES MORE OFTEN THAN PEOPLE CHANGE FUEL FILTERS. P.S. MY NEIGHBOR HAS A 2005 DODGE THAT HAD A LINE RUPTURE-LUCKY FOR HIM HE WAS IN HIS DRIVEWAY! *TR

STEERING, SERVICE BRAKES, HYDRAULIC
WAS BACKING OUT OF DRIVEWAY AND HIT BRAKES. PEDAL DEPRESSED FURTHER THAN NORMAL AND IT TOOK EXTREME EFFORT TO STOP THE TRUCK. I TRIED TURNING TRUCK OFF AND THEN RESTARTING IT TO SEE IF THAT WOULD FIX THE PROBLEM. IT DID NOT. I THEN TRIED TO STEER THE VEHICLE TO LINE IT UP WITH THE ROADWAY SO IT COULD BE TOWED EASILY. I WAS BACKING UP AND TRYING TO TURN THE WHEEL AND THE STEERING FELT LIKE IT WAS LOCKED. WITH EXTREME EFFORT I WAS ABLE TO TURN THE WHEEL WHILE CONTINUING TO BACK UP. SUDDENLY THERE WAS A LITTLE CHUNK NOISE THE WHEEL KICKED SLIGHTLY IN MY HANDS. I THEN HAD FULL POWER STEERING AND POWER BRAKES AGAIN. I IMMEDIATELY DROVE IT (SLOWLY) TO THE DEALER AND THEY TOLD ME EVERYTHING CHECKED OUT AND THAT IT WAS INTERMITTENT PROBLEM THAT THEY COULD NOT SOLVE. BOTH STEERING AND BRAKES FAILED, BUT THE DEALER COULD NOT REPRODUCE THE PROBLEM. *TR

SERVICE BRAKES, HYDRAULIC
WHILE APPLYING THE BRAKES, THE BRAKE PEDAL WENT TO THE FLOOR. THE VEHICLE BRAKING POWER WAS DIMINISHED AND THE BRAKING DISTANCE WAS SUBSTANTIALLY INCREASED. HAD ANOTHER VEHICLE OR STRUCTURE BEEN IN FRONT OF MY TRUCK THERE WOULD HAVE AN ACCIDENT WITH AIRBAG DEPLOYMENT AND INJURIES. A VISUAL INSPECTION OF THE BRAKING SYSTEM BY THIS WRITER REVEALED A RUPTURED BRAKE LINE. THE AREA OF THE RUPTURE AS WELL AS THE BALANCE OF THE SUSPECT BRAKE LINE WAS IN POOR CONDITION DUE TO CORROSION. THE REMAINING BRAKE LINES WERE FOUND IN A SIMILAR CORRODED CONDITION. THE CORRODED CONDITION WAS FOUND ON THE ENTIRE LENGTH OF THE BRAKE LINES UP TO WITHIN 6" OF THE MASTER CYLINDER. THE CORROSION WAS ALSO IN AREAS INCLUDING WHAT THIS WRITER WOULD CONSIDER "PROTECTED AREAS".

SERVICE BRAKES, HYDRAULIC
2004 GMC SIERRA EXT CAB WITH 40K MILES HAS SERIOUSLY DEGRADED BRAKING POWER. UPON SUDDEN STOPS THE VEHICLE WASN'T TO KEEP ROLLING TAKING FAR TO LONG TO STOP. THE PEDAL GOES ALMOST TO THE FLOOR AND YET THE TRUCK IS STILL MOVING. THE ABS SYSTEM DOES NOT INDICATE IT IS WORKING BUT THE WHEEL S DO NOT LOCK UP TO A SKID, IN FACT, I CAN'T GET THE TRUCK TO SKID OR INVOKE THE ABS SYSTEM NO MATTER WHAT I DO. I CALLED THE DEALER WHO SAID NO RECALLS WERE OUT FOR THIS PROBLEM BUT THIS IS DEFINITELY NOT RIGHT. DEALER SAYS IT'S NORMAL BUT I CAN BRING IT IN FOR AN INSPECTION ( $100) BUT ANY REPAIRS ARE NOT COVERED BY GM, HE ACTED LIKE HE NEVER HEARD OF THIS BEFORE? I HAVE HEARD OF SEVERAL OTHER GMC TRUCK OWNERS THAT SAID THEY HAD SIMILAR ISSUES ONLY TO BE CHARGED $800 OR MORE WITH LITTLE IMPROVEMENT. I CANNOT KEEP THIS TRUCK LIKE THIS, I AM AFRAID I WILL ROLL INTO THE BACK OF SOMEONE AND I CANNOT TOW MY TRAILER ( SMALL BIKE TRAILER) FOR FEAR OF THE SAME. WHEN WILL GM WAKE UP? *TR
