2004 Hyundai Elantra SERVICE BRAKES, HYDRAULIC

TRAVELING SOUTHBOUND ON INTERSTATE 5. ACCIDENT OCCURRED IN FRONT OF ME REQUIRING SUDDEN APPLICATION OF BRAKES (PANIC STOP). BRAKES FAILED COMPLETELY. THE BRAKES WORKED PARTIALLY AFTER SWERVING AND PUMPING THE BRAKES. IT WAS ALSO FOUND THAT THE BRAKES HAD FAILED COMPLETELY UPON BACKING THE VEHICLE. A MECHANICAL INSPECTION DETERMINED THAT THE ENGINE-BOOSTER VACUUM LINE CHECK VALVE HAD FAILED.

DT*: THE CONTACT STATED WHILE TURNING LEFT AT LOW SPEEDS THERE WAS A GRINDING NOISE THAT CAME FROM THE REAR OF THE VEHICLE. THE DEALERSHIP WAS UNABLE TO DETERMINE WHY THE REAR BRAKES HAD FAILED. THE VEHICLE WAS TAKEN TO A LOCAL INDEPENDENT REPAIR SHOP. THE MECHANIC DETERMINED THE REAR BRAKE SENSORS WERE BENT AND BOTH REAR BRAKES WERE REPLACED AND THE ROTORS WERE TURNED. THE MANUFACTURER HAS BEEN ALERTED.

CAR HAS BEEN SERVICED THREE TIME FOR GRINDING IN THE REAR OF CAR WHEN BRAKES ARE APPLIED. I HAVE NEVER BEEN TOLD WHAT THE PROBLEM IS, JUST THAT THEY HAVE FIXED IT, BUT IT NEVER STAYS FIXED. FIRST TIME (10/06/04) THEY LUBED BACKING PLATES AND SANDED SHOES; SECOND TIME (04/20/05) THEY REPLACED REAR BRAKE SHOES AND DRUMS; THIRD TIME (08/15/05) THEY REPLACED BOTH REAR WHEEL CYCLINDERS. I AM TREATED VERY WELL BY THE SERVICE DEPARTMENT PERSONNEL, BUT, I HAVE A CAR THAT CONTINUES TO HAVE BRAKE PROBLEMS. THIS IS A BAD ACCIDENT WAITING TO HAPPEN!. *AK

LOUD CLUNKING NOISE AND VIBRATION FROM REAR OF CAR WHEN BRAKING. TOOK IT TO DEALER AND THEY REPLACED WARPED ROTORS AND MACHINED BRAKE DRUMS AT 4,400 MILES. PROBLEM STARTED AGAIN AND EVEN WORSE AT 4,700 MILES. I WILL BE TAKING IT IN TODAY. I'M AFRAID THAT AFTER 12,000 MILES THE WARRANTY WILL NOT COVER THEM ANYMORE, EVEN THOUGH THEY ARE OBVIOUSLY DEFECTIVE AND HAVE BEEN FROM THE START.*AK
