Sheer Panic--No Brakes!

So my wife who likes to drive to the point of,"I don't know if I have enough gas to get to the station." Runs out on her way to the gas station. Calls me. She's about 75 yards from the station. I rush down to push her. Broke my back pushing her fwd Pontiac omg said your car is harder to push than my Roadrunner. She had it in gear....
