I have to double hit the brakes to get it to stop. I am asking people and no one knows whats going on. So I'm asking here. I was told the brakes were adjusted already. This isn't a new thing. It's been doing this for almost six months now but due to recent events I want them fixed. I love this car even though the body's going and the trannys going too. This is my concern now. Any ideas?
