MY WIFE HAD A SIMILAR SITUATION A FEW DAYS EARLIER AND I THOUGHT SHE HAD JUST HAD THE ABS WORKING AND WASN'T USED TO IT. THERE WAS NO ABS…

LEFT FRONT BRAKE ROTOR SEPARATED. THAT IS TO SAY, THE DISC ACTUALLY SEPARATED FROM THE HUB. THE SEPARATION CAUSED LOSS OF BRAKING ON THAT WHEEL. THE VEHICLE PULLS HARD TOWARD THE RIGHT(BECAUSE OF THE REMAINING ACTIVE BRAKE). CONCERNS: AN INEXPERIENCED DRIVER MAY HAVE ROLLED THE VEHICLE WITH THE SUDDEN HARD PULL TO THE RIGHT; HAD BOTH ROTORS FAILED AT THE SAME TIME, A COMPLETE LOSS OF FRONT BRAKES WOULD HAVE BEEN THE RESULT. I HAVE THE FAILED PART. THE REPAIR SHOP WHO FIXED THE VEHICLE TOLD ME THEY SEE THIS KIND OF FAILURE ON A REGULAR BASIS. THUS TYPE OF COMPOSITE ROTOR IS COMMON ON MANY GM VEHICLES. HAVING EXPERIENCED THE FAILURE, I CAN'T HELP BUT WONDER IF CRASHES MAY HAVE BEEN CAUSED BY THE ROTOR FAILURE, BUT THE "BROKEN" ROTOR COULD HAVE BEEN ASSUMED TO BE A RESULT OF THE CRASH? I HAVE NOT CONTACTED GM AT THIS POINT. I HAVE SEVERAL COMPLAINTS CONCERNING THIS VEHICLE I AM ATTEMPTING TO ADDRESS WITH GM, BUT FOR THE MOST PART AM BEING TOLD THE VEHICLE IS OUT OF WARRANTY. THIS IS A SAFETY ISSUE THAT I FELT NHTSA SHOULD BE AWARE OF, AND WILL, HOPEFULLY, LOOK INTO. THANK YOU, AND I HOPE TO HEAR FROM YOU SOON.*AK *TR

WHEN BACKING OUT OF THE GARAGE THE BRAKES FAILED. HAD I NOT REALLY PRESSED ON THE BRAKES EXTREMELY HARD I WOULD HAVE HIT THE MOTOR HOME THAT WAS ACROSS THE STREET FROM MY DRIVEWAY. I STOPPED ABOUT 5 INCHES FROM IT. I HATE TO THINK WHAT WOULD HAVE HAPPENED IF THIS HAD OCCURED WHILE I WAS ON THE FREEWAY AND MAKING AN EMERGENCY STOP. THIS COMPONENT FAILED WITHOUT ANY NOTICE. IT SHOULD NOT HAVE FAILED AT SUCH AN EARLY AGE AND IS OBVIOUSLY A DEFECT. I CALLED THE LOCAL DEALER , AND HE TOLD ME THAT THERE WAS NO SERVICE BULLETIN ON THE ISSUE, AND THAT I WOULD HAVE TO PAY FOR IT SINCE IT WAS OUT OF WARRANTY, SO I TOOK IT TO A LOCAL SHOP INSTEAD OF THE DEALER. THE CHEVY DEALER HAD THE NERVE TO TELL ME THAT IT WOULD BE ABOUT $500 TO REPLACE THE BOOSTER, AND THEY WOULD GIVE ME NO ASSURANCES THAT THE REPLACEMENT WOULD NOT FAIL IN THE SAME MANNER! *AK
