Hi all: I have a 2002 Dodge 2500 Cummins Automatic with 58,000 miles and lately I hear a noise which sounds like a roaring noise but it goes away when I press the brake pedal then returns when I let up the brake....Just had four new Michelins put on it but it made the noise before.. It started making the noise recently... Any idea what the problem might be? Regards; Mike...
