WHILE PERFORMING AN OIL CHANGE I NOTICED SEVERE BRAKE LINE CORROSION. THE TRUCK WAS IMMEDIATELY TAKEN TO MY LOCAL MECHANIC FOR INSPECTION AND IS NOW HAVING ALL BRAKE LINES REPLACED. THANKFULLY THE BRAKE LINES DID NOT FAIL WHILE I WAS DRIVING OR TOWING A TRAILER. I HAVE A 1989 CHEVY SILVERADO 2500 THAT HASN'T HAD CORROSION PROBLEMS LIKE THIS NEWER ONE. AFTER SOME GOOGLING I FOUND OUT THAT THERE IS AN INVESTIGATION IN TO THIS MATTER AND THAT MANY OWNERS HAVE HAD THEIR BRAKES FAIL WHILE DRIVING. THE NHTSA NEEDS TO STEP UP AND HOLD GM ACCOUNTABLE. SURE, IT WILL BE AN EXPENSIVE RECALL BUT IF GM DOES THE RIGHT THING IT WILL SHOW THAT THEY CARE ABOUT THE SAFETY OF AMERICANS AND WILL MAKE MANY BRAND-LOYAL CUSTOMERS HAPPY. THIS MATTER IS VERY SERIOUS, ESPECIALLY CONSIDERING WHAT THE MAJORITY OF THESE HD TRUCKS ARE USED FOR...HAULING, TOWING, ETC. *TR

THERE WAS A RECALL ISSUED PRIOR TO THIS DATE FOR OVER 800,000 SILVERADO TRUCKS INCLUDING THE YEARS 99-2002 FOR THIS EXACT ISSUE.

WHILE APPROACHING THE BACK OF ANOTHER VEHICLE WHILE IT WAS TAKING A LEFT HAND TURN, I APPLIED MY BRAKES AND HAD NONE, THE PEDDLE WENT TO THE FLOOR AND I COULD NOT STOP. I DOWN SHIFTED THE TRUCK INTO LOW GEAR WHICH IS WITH AN AUTOMATIC TRANSMISSION AND APPLIED THE EMERGENCY BRAKE. I HAD THE TRUCK TOWED TO A REPAIR SHOP WHERE I WAS TOLD THE BRAKES ARE ROTTED AND LINE RUPTURED. I UNDERSTAND THERE ARE A LOT OF PROBLEMS WITH THE BRAKE LINES ON THESE VEHICLES AND SOMETHING SHOULD BE DONE ABOUT THEM. SURELY THEY ARE MADE OF INFERIOR MATERIALS BECAUSE THIS PROBLEM IS NOT HAPPENING WITH OTHER TRUCKS MODELS LIKE FORD, DODGE, OR TUNDRA. TRUCK IS NOW AT STEVE'S ACCURATE AUTO REPAIR, MADBURY NH. *TR
STEEL BRAKE LINE RUSTED OUT & LEAK WHILE TRYING TO STOP PULLING A TRAILER WHEN TRYING TO STOP AT STOP SIGN ALL LINES RUSTED OUT. I AM A AUTO MECHANIC AND HAVE 3 CHEVROLET TRUCKS WITH RUSTED LINES + A CHEVROLET CAVALIER CAR WITH RUSTED LINES ALSO ALL AT THE SAME TIME! *TR
