DRIVING DOWN HIGHWAY, APPLIED BRAKES TO FEEL THE PEDAL GO TO FLOOR. ABLE TO STOP AND INSPECT AFTER SOME DISTANCE. REAR STEEL BRAKE LINE UNDER TRUCK BED HAD CORRODED THROUGH, AND WITH A PUSH OF THE PEDAL, BRAKE FLUID SPRAYED EVERYWHERE. HAD TO HAVE LINE REPLACED FROM DIVERTER BOX UNDER CAB TO REAR CROSSOVER AT DRIVER REAR WHEEL, BADLY CORRODED! NOW IT IS MARCH OF 2012 (107,000 MILES), AND THE FRONT LINES FROM THE MASTER CYLINDER TO DIVERTER ARE LEAKING AS WELL. THANKFULLY I NOTICED BEFORE DRIVING. I AM HAVING THE BAD LINE REPLACED, AND I AM LOOKING FOR A STAINLESS STEEL REPLACEMENT FOR ALL LINES! *TR

I OWN A 2002 CHEVY SILVERADO 2500 ON WHICH I HAVE FOUR MICHELIN LTX M/S 245/75-16 TIRES. AFTER 18 MONTHS AND 10,000 MILES THE SIDEWALLS BEGAN TO CRACK. I HAVE MICHELIN TIRES ON ALL FOUR OF MY VEHICLES AND HAVE NEVER HAD ONE CRACK EVEN ON 6 YEAR OLD TIRES. I CALLED MICHELIN, BUT THEY SAY THAT IS NORMAL WEATHERING. NOW THEY ARE CRACKING TO THE POINT THAT THE TREAD COULD EASILY SEPARATE. MY TIRE DEALER IS GOING TO REPLACE THEM, BUT MICHELIN WILL NOT REIMBURSE THEM AS MICHELIN DENIES THERE IS A PROBLEM. I SEE FROM ONLINE BLOGS THAT SIDEWALL CRACKS IN THIS TIRE ARE APPEARING ALL OVER THE COUNTRY AND MICHELIN IS STONEWALLING IT. THIS IS A LIFE THREATENING SITUATION WHICH SHOULD BE INVESTIGATED. *TR *JS

TL* THE CONTACT OWNS A 2002 CHEVROLET SILVERADO 2500 HD. WHILE DRIVING APPROXIMATELY 5 MPH AND DEPRESSING THE BRAKES, THE ABS ACTIVATED ERRONEOUSLY. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTICS WHERE THE TECHNICIAN STATED THAT THE FRONT DRIVER SIDE SPEED SENSOR WAS CORRODED AND WOULD HAVE TO BE CLEANED. THE FAILURE CONTINUED AFTER THE SPEED SENSOR WAS CLEANED. THE CONTACT REPLACED THE FRONT PASSENGER SIDE WHEEL BEARING, HUB ASSEMBLY AND SPEED SENSOR INDEPENDENTLY YET THE FAILURE PERSISTED. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 133,000.

WE HAVE JUST HAD 27 FEET OF FRONT BRAKE LINE REPLACED FOR THE SECOND TIME IN OUR 2002 CHEVY SILVERADO 2500 SERIES. TWO YEARS AGO LOST BRAKES AND LUCKILY AVOIDED AN ACCIDENT. GM DEALERSHIP REPLACED, AND THE LINE FAILED YET AGAIN LAST WEEK. THIS TIME MY 19-YEAR-OLD SON WAS DRIVING WITH A PASSENGER. LUCKILY, HE AVOIDED THE CARS IN FRONT OF HIM AT A STOP LIGHT BY CROSSING TWO LANES SO THAT HE COULD SLOW THE VEHICLE DOWN ON THE GRASSY ROADSIDE. REFUSED TO TAKE TO GM FOR REPAIR THIS TIME. SOMETHING HAS TO BE DONE ABOUT FAULTY CHEVY BRAKELINES IN EARLY 2000 CHEVY TRUCKS BEFORE SOMEONE LOSES THEIR LIFE. *TR
COMPLETE BRAKE FAILURE WHEN I APPLIED THE BRAKES TO STOP. ALL BRAKE LINES COMING OUT OF THE BLOCK BY THE DRIVERSIDE FRONT DOOR ARE RUSTED BEYOND RECOGNITION. REAR BREAK LINE FAILURE OCCURRED IN 2010 SAME BRAKE LINE CONDITION. I KEEP MY TRUCK CLEAN AND DO NOT OFF ROAD WITH IT. *TR
