Brake Grinding Noise problems of the 2005 Mazda Tribute

I purchased the car new in 2004. I have been complaining about the brakes losing pressure since I purchased my car but the dealership always told me they were fine. I have always had to push my brakes to the floor to stop the vehicle. Sometimes when at a red light I'd sit and pump air into the brakes so they would stop properly. Yesterday I was driving in stop and go traffic and a lady stopped ahead of me but my car would not stop. I had adequate distance to stop. I had the brake pedal to the floor and it felt as if the tires were stuttering/hopping in an attempt to stop. I pressed so hard that my whole leg was in a cramp. I hit the car ahead of me damaging the bumper. I did not slide, the tires are semi-new and in great condition. Also, my rotors failed a few years ago. Had to have them replaced all round as well as another part of the braking system. I have also had the grinding noise and the air hissing from the brakes. This has been an issue for a long time and I've asked Mazda about recalls and their haven't been any. With the number of complaints on the internet I don't feel it is right for the consumers to have to continue paying financially, through insurance or personal injury for the manufacturer's default.

The vehicle has been to the dealer twice and they were unable to correct the problem. Each time the dealer lubricated the calipers and smoothed the rotors.
