RUSTED BRAKE LINES (BOTH) RUSTED AND FAILED AT A CRITICAL TIME PUTTING MOTORIST IN DANGEROUS SITUATION AT TIME OF FAILURE. EXITING HIGHWAY AT POSTED SPEED WITH FEW OPTIONS ON HOW TO STOP VEHICLE.

WHILE TRAVELING AT HIGHWAY SPEED AND ROUNDING A BLIND CURVE THE TRAFFIC AHEAD HAD STOPPED DUE TO A CRASH. I HAD TO BRAKE HARDER THAN NORMAL AND THE BRAKE PEDAL JUST KEPT DEPRESSING FURTHER AND FURTHER UNTIL IT WAS ALL THE WAY TO THE FLOOR. I WASN'T STOPPING NEAR FAST ENOUGH AND HAD TO VEER TO THE LEFT INTO THE MEDIAN TO AVOID MAKING CONTACT WITH ANYONE ELSE. IT WAS RAINING AND AS I LOOKED UNDER MY TRUCK TO LOOK FOR WHY MY BRAKES WERE INEFFECTIVE BUT COULDN'T SEE ANYTHING AT THAT TIME. I CHOSE TO TRY TO DRIVE HOME NOT SURE WHY I HAD THE PROBLEM STOPPING. THE NEXT DAY WAS DRY AND I HAD MY BROTHER PUMP THE BRAKES WHILE I LOOK UNDERNEATH AND FOUND NUMEROUS PLACES WHERE THE BRAKE LINES WERE RUSTING AT AN ALARMING RATE AND ONE LOCATION WHERE THE RUSTED LINE FAILED. I REPAIRED THE LEAK I HAD FOUND AND WHEN I TRIED TO BLEED THE BRAKES FROM THAT REPAIR I WOULD BEGIN AN UNENDING RUN OF LEAKS UP AND DOWN THE METAL BRAKE LINES FOR BOTH THE FRONT AND REAR. THIS YUKON HAS AROUND 260K MILES BUT THOSE BRAKE LINES SHOULDN'T BE RUSTING THROUGH LIKE THEY ARE. I HAVE HAD MORE THAN 15 TAHOES, YUKONS, YUKON XLS, SUBURBANS, AND PICKUP TRUCKS FROM GM AND NEVER HAVE I HAD SUCH A RUN OF BRAKE FAILURES AS THIS 2004 MODEL YUKON WAS NOW GOING THROUGH. GM SAYS THIS IS NORMAL MAINTENANCE BUT HOW CAN ONE EVEN SEE IF A FAILURE IS OCCURRING AS MANY OF THESE LINES ARE CONCEALED BY THE FRAME, CHASSIS, AND BODY. I HAVE SPOKEN TO OTHER OWNERS OF SIMILAR VEHICLES, BE IT PICKUPS OR TAHOE'S OR SUBURBANS OF THE 2000 TO 2006 MODEL YEARS AND NEARLY ALL HAVE COMPLAINED OF CHRONIC BODY RUST ISSUES BUT MORE IMPORTANTLY BRAKE FAILURES FROM BRAKE LINES RUSTING AND THEN BLOWING OUT WITHOUT WARNING. MANY ALSO CITED THAT OF THE LINES THAT ARE VISIBLE TO INSPECT THEY WOULD APPEAR TO BE OK BUT JUST OUT OF VIEW ONE WOULD HAVE A SUDDEN BLOW OUT WITH NO WAY TO SEE OR KNOW THERE WAS A PROBLEM SINCE THE LINES ARE CONCEALED.

TL* THE CONTACT OWNS A 2004 GMC YUKON. WHILE MOVING FROM THE PARK POSITION, THE BRAKE SYSTEM DISABLE WARNING INDICATOR ILLUMINATED. THE BRAKE PEDAL WAS DEPRESSED, BUT FAILED TO OPERATE. THE EMERGENCY BRAKES ALSO FAILED TO OPERATE. THE CONTACT STATED THAT THERE WAS BRAKE FLUID EVIDENT UNDER THE FRONT OF THE VEHICLE. THE CONTACT ALSO STATED THAT THE BRAKE LINE WAS EXTREMELY CORRODED. THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 04V045000 (SERVICE BRAKES, HYDRAULIC). THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 152,000.

WHILE DRIVING DOWN ROAD AT APPROXIMATELY 45 MPH, HIT THE BRAKES WHEN A COUPLE OF DEER JUMPED ONTO ROAD AND THE PEDAL WENT TO FLOOR WITH NO BRAKING ACTION AT ALL. HAD ENOUGH TIME TO REALIZE WHAT HAD HAPPENED AND HIT THE PARKING BRAKE IN TIME BEFORE REACHING INTERSECTION TO BUSY HIGHWAY. INSPECTION AFTERWARD SHOWED BRAKE FLUID ON THE FRAME NEAR THE DRIVER SIDE DOOR WHERE THE PROPORTIONING VALVE IS LOCATED. THERE WAS NO WARNING OF THE FAILURE AND HAD BEEN DRIVING THE VEHICLE AROUND TOWN MOST OF THE DAY. HAVE EXPERIENCED BRAKE FAILURES ON VEHICLES BEFORE AND ALWAYS HAD HALF THE SYSTEM REMAIN OPERATIONAL ENOUGH TO STOP WITHOUT PROBLEM. THIS APPEARS TO HAVE BEEN A SINGLE FAILURE MODE THAT CAUSED THE LOSS OF BRAKING OR A SIMULTANEOUS FAILURE OF MULTIPLE SYSTEMS WHICH SHOULD BE UNLIKELY BUT SEEMS TO HAPPEN WITH IMPROBABLE REGULARITY BASED ON COMPLAINTS POSTED.

I WENT TO BACK OUT OF MY DRIVEWAY AND THE BRAKE PEDAL WENT TO THE FLOOR. I LOOKED UNDER THE VEHICLE AND NOTICED A RUSTED BRAKE LINE HAD BURST. I WAS ABLE TO PARK IT SAFELY BACK IN THE DRIVEWAY. I TAKE CARE OF MY TRUCK AND IS SERVICED REGULARLY BY THE DEALER.

STEEL BRAKE LINES HAVE RUSTED THROUGH, CAUSING LEAKAGE AND TOTAL BRAKE FAILURE DURING APPLICATION. CALIPERS AND BLEEDER VALVES ALSO RUSTED, PREVENTING NEW BRAKE LINES FROM BEING RE-ATTACHED.

BRAKE LINES RUSTED IN TO CAUSING THE LINES TO WEAKEN. DRIVING TO MY HOUSE , PUSH ON BRAKE PEDAL IT WENT TO THE FLOOR LOOK UNDER VEHICLE AND THERE WAS A POOL OF BRAKE FLUID UNDER THE VEHICLE. THIS COULD HAVE BEEN A SERIOUS ACCIDENT IN TRAFFIC.

WHILE DRIVING DOWN AN ON RAMP I BEGAN TO APPLY THE BRAKES TO SLOW DOWN, THE BRAKE PEDAL SUNK TO THE FLOOR AND I HAD NO BRAKING CAPABILITY AND THE BRAKE WARNING APPEARED ON THE DASH. I PUMPED THE BRAKE AGAIN AND STILL HAD NO BRAKING CAPABILITY, I WAS ABLE TO COAST TO A STOP ALONG THE SIDE OF THE ROAD. UPON INSPECTION OF THE BRAKE LINES, THERE WAS A MAJOR LEAK ON THE REAR DRIVER SIDE, AND A SMALLER LEAK FROM ON THE FRONT PASSENGER SIDE.

TL* THE CONTACT OWNS A 2004 GMC YUKON XL. WHILE DRIVING AT ANY SPEED AND APPLYING THE BRAKES, THE PEDAL WOULD STIFFEN AND NOT MOVED DOWNWARD COMPLETELY. THE FAILURE RECURRED CONTINUOUSLY. THE VEHICLE WAS DRIVEN TO A MECHANIC WHO DIAGNOSED THAT THE POWER ASSIST BRAKE SYSTEM FAILED. THE VIN WAS EXCLUDED FROM NHTSA CAMPAIGN NUMBER: 04V045000 (SERVICE BRAKES, HYDRAULIC). THE MANUFACTURER WAS NOTIFIED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 130,000.

WHILE OPERATING THE VEHICLE ON A HIGHWAY I PRESSED THE BRAKE PEDAL AND SUDDENLY THE BRAKE PEDAL SUNK AND I LOST BRAKES. I NEARLY LOST CONTROL OF THE VEHICLE AND ALMOST DROVE INTO A GUARD RAIL. AFTER FURTHER INSPECTION I OBSERVE THE FRONT DRIVERS SIDE BRAKE WAS CORRODED CAUSING IT TO BREAK. THIS APPEARS TO BE AN ISSUE WITH GMC AND THE COMPANY SHOULD BE REQUIRED TO RECTIFY THE SITUATION. USING STAINLESS WOULD PREVENT INCIDENTS LIKE THESE AND POSSIBLE INJURIES OR DEATHS.

DRIVING AT 35 MPH WHEN THE BRAKES SUDDENLY STOPPED WORKING WITH NO INDICATION PRECEDING INCIDENT. VEHICLE MADE CONTACT WITH CURB BEFORE COMING TO A COMPLETE STOP. DISCOVERED REAR BRAKE LINES HAD COMPLETELY CORRODED THROUGH AND VEHICLE WAS LOSING FLUID. APPARENTLY THIS IS A KNOWN PROBLEM THAT GM REFUSES TO FIX. *TR

I WAS TRAVELING ON SATURDAY MORNING, IN MY DADS 2004 YUKON LUCKILY IT WAS EARLY ENOUGH NOT MUCH TRAFFIC AT THE TIME, IT WAS RAINING AND I WAS NOT DRIVING VERY FAST NORMAL SPEED ON THE HIGHWAY IS 40 MILES PER HOUR ON US11 BECAUSE OF CONGESTION AND TRAFFIC LIGHTS, I WAS TRAVELING BETWEEN 30 AND 35 MPH BECAUSE OF RAIN, ANYWAYS A LIGHT CHANGED AND I HAD TIME TO STOP, BUT THE VEHICLE DID NOT STOP THE PEDAL WENT ALMOST TO THE FLOOR AND THE LIGHT CAME ON STATING BRAKE FAILURE, FROM THAT POINT I SLOWED DOWN AS SLOW AS I COULD AND TRIED TO TEST THE BRAKES, IT WOULD STOP, BUT NEEDED PLENTY OF DISTANCE, SO I SLOWED FOR A TURN OFF, AND WHEN I GOT HOME, STARTED TO BRAKE BEFORE ENTERING THE DRIVEWAY SO THAT I WOULD NOT HIT THE GARAGE OR ANYTHING ELSE, IN FACT I STOPPED THE VEHICLE AT THE END OF THE DRIVEWAY NEAR THE ROAD. *TR

EXCESSIVE CORROSION ON BRAKE CALIPERS, BLEEDERS AND ALL BOLTS ARE RUSTED AND UNMOVABLE. BRAKE LINES ARE RUSTED AND LEAKING. *TR

BACKING UP TO HOOK UP A TRAILER, I DEPRESSED THE BRAKE AND IT WENT STRAIGHT TO THE FLOOR. REAR BRAKE LINE RUPTURED AFTER ABS MODULE AND RIGHT ABOUT THE FUEL TANK. I CANNOT REPLACE JUST THEY ONE LINE BECAUSE OF CORROSION AND RUST AT THE MODULE. THIS IS THE FAMILY SUV AND IM LUCKY THIS HAPPENED IN MY YARD AND NOT ON THE HIGHWAY. I WAS PREPARING TO LEAVE TOWING A 5500LB TRAILER. ALL THESE OTHER LINES ARE EQUALLY BAD AND I FEAR THEY ARE GOING TO RUPTURE TOO. I'M STUCK WITH A 10 YEAR OLD LESS THAN SAFE VEHICLE. *TR
