WITHOUT ANY WARNINGS WHEN ATTEMPTING TO COME TO A QUICK STOP BRAKE PEDAL WENT TO THE FLOOR AND HAD NO BRAKING POWER. AVOIDED CRASH BY DRIVING ONTO A LAWN. I HAVE FOUND THAT ALL THE BRAKE LINES WHERE THEY ARE ATTACHED TO THE FRAME IN A PLASTIC SUPPORT UNDER THE DRIVERS DOOR HAVE ROTTED THROUGH. CONTACTED GMC WITH NO SUCCESS JUST INFORMING THEY ARE AWARE BUT NO RE-CALLS. *TR

SERVICE BRAKES
EXPERIENCED COMPLETE FAILURE OF THE BRAKING SYSTEM. FORTUNATELY THE VEHICLE WAS ONLY TRAVELING 15MPH AND IN AN AREA THAT WASN'T CONGESTED WITH TRAFFIC. I WAS ABLE TO STOP BY USING THE ROADSIDE BERM BANKING AND AVOIDED ANY FURTHER DAMAGE. VEHICLE WAS TOWED TO A NEARBY GM DEALERSHIP WHERE IT WAS DETERMINED THAT BOTH BRAKE LINES HAD CORRODED SO BADLY IT CAUSED THE LINES TO RUPTURE RESULTING IN AN IMMEDIATE LOSS OF PRESSURE AND COMPLETE BRAKE FAILURE. JUST DAYS EARLIER I HAD THE BRAKES SERVICED AT A DIFFERENT GM DEALERSHIP NEAR MY HOME AND THERE WAS NO MENTION OF THIS CONDITION NOR THE PREVIOUS REPORTS OF THIS PROBLEM FROM OTHER OWNERS AS NOTED ON THIS WEB SITE. EVEN IF GM OR THE NHTSA DOES NOT DEEM THIS ISSUE FREQUENT ENOUGH TO ISSUE A TSB, AT MINIMUM A SERVICE WARNING/RECOMMENDATION SHOULD BE ISSUED TO GM DEALERSHIPS AND OTHER REGISTERED SERVICE PROVIDERS ALERTING THEM TO INSPECT FOR THIS CONDITION WHILE SERVICING THE BRAKING SYSTEMS FOR THESE MODEL YEARS. DEATH OR SERIOUS INJURY CAN AND MOST LIKELY WILL OCCUR AS THERE ARE MANY VEHICLES FROM THESE MODEL YEARS STILL ON THE ROAD. *TR

SERVICE BRAKES
I HAD NOT DRIVEN MY TRUCK IN A FEW MONTHS DUE TO OTHER PROBLEMS WITH THE VENTILATION CONTROLS. WHILE BEGINNING TO PREPARE THE TRUCK TO TOW A 3500 POUND BOAT I NEEDED TO REPOSITION THE TRUCK IN MY DRIVEWAY. THE DRIVEWAY SLOPES DOWN TO THE STREET. WHILE MOVING THE TRUCK, ON MY DRIVEWAY, THE BRAKE PEDAL WENT COMPLETELY TO THE FLOOR. PUMPING THE BRAKES WAS NOT ABLE TO STOP THE TRUCK THAT WAS TRAVELING AT IDLE SPEED. ALL BRAKING WAS GONE AND THE TRUCK ROLLED DOWN THE DRIVEWAY AND INTO TRAFFIC ON MY STREET. BY TURNING OFF THE ENGINE AND COASTING TO A STOP (IN GEAR) JUST AVOIDED AN ACCIDENT. AFTER GETTING THE TRUCK BACK IN MY DRIVEWAY I FOUND TWO DISTINCT PUDDLES OF BRAKE FLUID UNDER THE TRUCK. INSPECTING THE BRAKE LINES SHOWED THAT THERE WERE AT LEAST TWO DIFFERENT FAILURE POINTS IN THE BRAKE LINES. ONE CLOSER TO THE MASTER CYLINDER AND ANOTHER A FEW FEET FURTHER BACK. I BELIEVE ONE FAILURE OCCURRED IN THE FRONT BRAKE CIRCUIT AND THE OTHER WAS IN THE REAR BRAKE CIRCUIT WHICH LED TO THE *COMPLETE* LOSS OF BRAKING. THIS IS CONTRARY TO GM CLAIMS THAT THIS FAILURE CAN NOT LEAD TO TOTAL BRAKE LOSS. I HAVE PICTURES AND VIDEO OF THE FAILURE POINTS THAT I CAN FORWARD IF NEEDED. *TR

AS A MINIVAN IN FRONT OF ME PUT THEIR LEFT TURN SIGNAL ON LATE, I HAD TO HIT MY BRAKES QUICKLY AND WHEN I DID MY BRAKE PEDAL WENT TO THE FLOOR AND I WAS PUMPING AIR AND HAD NO BRAKES AT ALL. I SWIRVED AROUND THE VAN AND LUCKILY I WAS ON AN INCLINED ROAD AS I WAS ABLE TO SLOW THE VEHICLE DOWN INTO A LOT AND THEN PULLED THE EMERGENCY BRAKE TO GET THE TRUCK STOPPED. MY FRONT AND BACK BRAKE LINE BLEW OUT AND MY MECHANIC SAID I WAS LUCKY THAT I WASN'T KILLED. NOW THE TRUCK IS NOT USABLE AND THE AFTER 52,000 MILES I FEEL THIS IS A SITUATION OF DEFECTIVE BRAKE LINES. *TR

DRIVING VEHICLE, AND LOST BRAKES. DISCOVERED THE BRAKE LINE HAD RUSTED THRU CAUSING LOSS OF FLUIDS. AFTER RESEARCHING THIS I FOUND OUT THIS IS A VERY COMMON PROBLEM WITH CERTAIN YEAR MODEL GM VEHICLES. THIS IS A EXTREMELY DANGEROUS SITUATION, AND I CANT BELIEVE THERE HAS NOT BEEN A RECALL ON THIS. DOES IT REALLY TAKE DEATHS FOR GM TO ACT ON DEFECTS THEY ARE AWARE OF? I HAVE A 1988 JEEP WRANGLER AND THE BRAKE LINES LOOK A LOT BETTER THAN THOSE ON MY TRUCK. THE SAD THING IS YOU CANT EVEN BUY THE BREAK LINES FROM THE DEALER BECAUSE THEY DON'T SELL THEM, WOULD SOMEONE PLEASE LOOK DEEPER INTO THIS BEFORE SOMEONE ELSE GETS KILLED OR INJURED. *TR

THE BRAKE LINES IN MY 1999 GMC SIERRA BLEW OUT, AND I WAS BARELY ABLE TO STOP THE TRUCK BEFORE ENTERING A BUSY HIGHWAY FROM MY DRIVEWAY - THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR, PROVIDING VERY LITTLE BREAKING POWER AND TAKING A MUCH LONGER TIME TO STOP AND A MUCH LONGER DISTANCE TO STOP THAN NORMAL . I WAS INFORMED THAT MY BRAKE LINES HAD COMPLETELY RUSTED OUT, NEEDING FULL REPLACEMENT, WHICH I HAD DONE LAST WEEK AT CONSIDERABLE EXPENSE. IT IS UNCONSCIONABLE THAT GM KNEW ABOUT THIS PROBLEM AND FAILED TO INFORM OWNERS OF THEIR VEHICLES TO HAVE THEIR BRAKE LINES INSPECTED! I HAVE OWNED THIS TRUCK SINCE IT WAS NEW, AND MY ADDRESS HAS NOT CHANGED SINCE IT WAS PURCHASED, SO MY ADDRESS IS IN THEIR FILES. *JS
