My daughter was traveling north at 40 mph, and she turned around briefly to check if her little brother was buckled in his seat belt. when she turn back around the car was on the curve and she slammed on the brakes as hard as she could to stop the car, but the car wouldn't stop and preceded to accelerate. she went through partially two brick walls, knocked down a stop and street sign, and the car flipped a couple of times. the car ended up landing on the passenger side, leaving the car left side up. my daughter suffered injuries to the neck, back, and her knees were cut from the glass of the window in a result of the car crashing. luckily, my son suffered no injuries. i am very concerned, why did the brakes fail in my daughter's attempt to stop the vehicle. *tr
