I have a 2001 Lincoln continental and my brake pedal as i press down slowly on the pedal the actual pedal kicks back as I'm braking it gets worst then i also hear some weird sound coming from the engine almost as if the abs or something is trying to condensate for whats going on. I have checked the brake fluid its good. Brake pads have been replaced almost a month ago. It almost seems like its the rotors but it does it only as I'm pressing on the brake pedal and its getting worst. Can someone please help me... give me a direction on what to test or look at to pin point the problem before it gets worst..
