1996 Chevrolet M Series Problems

IT WAS A RAINING DAY, PICKED UP DAUGHTER AT A HOUSE ON THE DOWNPART OF A HILL. CAR WAS IN PARK, TOOK THE CAR OUT OF PARK TO DRIVE DOWN THE HILL, MY FOOT NEVER TOUCHED THE ACCELERATOR DUE TO BEING ON THE DOWN PART OF THE HILL, MY BRAKES STARTED TO PULSATE VIGOROUSLY , I KNEW NOT TO PUMP THE BRAKES BUT I ALSO KNEW THAT MY VAN WAS NOT STOPPING, THERE WAS A CAR AT THE BOTTOM OF THE HILL AT A STOP SIGN, I HAD BOTH FEET ON THE BRAKES, THEY PULSATING SO HARD I COULDN'T KEEP MY LEGS STILL, I WENT TO TURN MY STEERING WHEEL THINKING IF I TURNED INTO THE BUSHES I WOULD AVOID HITTING THE CAR AND GOING INTO THE MAIN STREET. MY STEERING WHEEL WOULD NOT TURN. I KNEW AT THIS POINT I WOULD HIT THE CAR AT THE BOTTOM OF THE STREETK, (MY CAR WAS NOT STALLED BECAUSE I LOOKED ON DASH BOARD TO MAKE SURE THERE WAS NOT WARNING SIGNALS0I PUSHED THE CAR INTO MAIN STREET HE TURNED AND I WENT STRAIGHT AHEAD INTO A HOUSE, I THREW THE CAR IN PARK AFTER I HIT THE CAR AND THE VAN STILL MOVED FORWARD INTOTHE HOUSE. THE GIRL IN THE BACK SEAT WENT FLYING TO FRONT AND BROKE HER ANKLE, ME AND MY DAUGHTER IN THE FRONT WERE ALRIGHT, I SUFFER FROM PELVIC PAIN AND BACK PAIN BUT THERE ARE N O FRACTURES THAT WERE VISIABLE. I STILL DO NOT HAVE MY VAN BACK AND THIS IS USED FOR MY DAUGHTER WHO IS IN A WHEELCHAIR. THE VAN HAS AN ELEVATOR LIFT IN IT. THE INS. CO. ARBELLA INS. HAD A SPECIALIST TEST BRAKES, HE CLAIMS EVERYTHING IS ALRIGHT BUT I KNOW FOR A FACT THAT THE BRAKES ARE ALMOST TO THE FLOOR AND MY EMERGENCY BRAKES ARE NOT WORKING AND I KNOW THEY WERE BOTH FINE BEFORE THE ACCIDENT BECAUSE TWO WEEKS PRIOR TO ACCIDENT I HAD THE BRAKES CHECK.*AK
