While dragging the trash can back to the house, I was approaching fence in front of the house, at a slow speed, as I applied the brakes the car started to accelerate. Pressing down harder on the brakes ,it felt like stepping on a brick, with no braking taking place the car accelerated at a high rate. At this time the car crashed into the left side of the garage and continued into the cement porch taking out the fence, fill tube, and vent tube of the oil tank. At this time I push gear shift into N and turned off the engine. At this time there is damage done to house and car is now totaled with no injuries. Hate to think what would have happened if this happened at the major 4 lane intersection 1 mile from my home.
