2000 TOYOTA SIENNA — SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP

MY TOYOTA SIENNA 2000 MIGHT HAS AN ABS SYSTEM MALFUNCTION AND CAUSED A MINOR ACCIDENT ON AUG 28 2007 AT 3:30 PM. THE WEATHER ~90C AND SUNNY. I DROVE IN SCHOOL ZONE AT THE TIME THE SCHOOL OVER AND THE STUDENTS PRESENTED ON THE SIDEWALK. I DROVE ~20-25 MPH OR LESS. THE DISTANCE BETWEEN MY VAN AND THE CAR IN FRONT OF ME ~ 2 CARS SPACE. THE CAR IN FRONT OF ME STOPPED SUDDENLY BECAUSE OF ONE CAR IN FRONT OF US TURNED LEFT OR MADE A U TURN WITHOUT WARNING. I STEPPED ON MY BRAKE PEDAL VERY HARD BUT THE VAN STILL CRUISED LIKE THE BRAKE WAS DOING ANYTHING AND I HIT TO THE REAR END OF THE CAR IN FRONT OF ME. MY CAR HAVE 133,000 MILE ON IT. I HAD MY FRONT BRAKE REPLACED BY DEALER WHEN IT 100,000 MILE, THE SAME TIME THEY REPLACED THE TIMING BELL, THEY TOLD ME THE REAR BRAKE WERE IN GOOD CONDITION AT THAT TIME SO I DIDN'T HAD IT REPLACED. TILL NOW, I STILL HAVE NOT HEARD ANY NOISE FROM MY BRAKE, NO WARNING INDICATOR LIGHT, AND IT HAS BEEN ALWAYS REACTING CORRECTLY EVERYTIME I STEPPED ON THE BRAKE PADDLE UNTIL THE DAY MY CAR INVOLVED INTO THE ACCIDENT. I PLAN AFTER FIXING THE BODY OF MY VAN, I WILL SEND IT TO TOYOTA DEALER FOR A BREAK AND ABS SYSTEM CHECK OR INSPECTION. I HAVE A NEIGHBOR ALSO HAVE A TOYOTA SIENNA 1999 VAN AND HE TOLD ME THAT HE ALSO INVOLVED IN ACCIDENT LAST YEAR AT THE LOW SPEED AND THE ABS SYSTEM DIDN'T WORK ALSO. AND HE BROUGHT IT TO THE DEALER FOR INSPECTION, THEY FOUND NOTHING WRONG AND HIS VAN HAD NOT FAILED AGAIN. I HOPE IF THERE IS PROBLEM OF TOYOTA SIENNA
