2004 Honda Accord Brakes

Brakes problem
2004 Honda Accord 6 cyl Wheel Drive Type unknown Automatic 42000 miles

My brakes don't seem to respond. My car will start slowing down, but then accelerate a little. A week ago, when I pressed on my brakes my car started to slow down, but then it jolted and it alsmost felt like my car was going to stop. I've had a number of problems with this car, which is strange because it's a Honda. I've probably taken it to the dealer more than 10 times for different problems, but the brakes seem to be an occuring problem. I've had the master cylinder changed 3 times and the brake hose once and I'm still having problems. Please help. Thanks!
