2001 Honda Odyssey brakes problems

Tl*the contact owns 2001 honda odyssey. The contact stated as she approached a traffic light and depressed the brake pedal, the vehicle continued to accelerate through a traffic light and caused her to lose control of the vehicle. The vehicle hit a tree and rolled over three times. The road conditions were not a factor. She had to go to the hospital with injuries to the left shoulder. A police report is available if needed. The honda manufacturer was not called.

While attempting to stop our 2001 odyssey in my son's school parking lot the brake pedal--without any prior warning--went to the floor and I coasted past my intended stopping point by about 20 feet. Luckily no person or vehicle was directly in front of me at that time. I was able to restore brake function by pumping the brake pedal. The next day my mechanic examined the brake master cylinder and found brake fluid leaking into the brake booster.
