THE ACCIDENT THAT HAPPENED IN OCTOBER WASN'T REPORTED BECAUSE IT WAS A SINGLE VEHICLE ACCIDENT AND THE PAVEMENT WAS WET. I FIGURED IT WAS MY FAULT AND NOT THE BRAKES. AT THE SECOND ACCIDENT, THE PAVEMENT WAS DRY AND THE COLLISION WAS WAS A RESULT OF THE BRAKES FAILING. I CAN ONLY CONCLUDE THAT BRAKES DURING THE FIRST TIME WERE A COMPELLING FACTOR TO THE ACCIDENT. I WENT TO THE DEALERSHIP TO COMPLAIN ABOUT PROBLEMS I HAD BEEN EXPERIENCEING WITH THE BRAKES BEFORE BOTH ACCIDENTS. THEY ONLY TOLD ME THAT THERE WAS NOTHING WRONG WITH THE TRUCK.( DOT NUMBER: TIRE SIZE: 235 )
