Gentleman, Fellow M7 Lovers. I Havea Big Problemon My Hands, My Lscse Has Given Me A Brake Problem Thats Too Complicated To Figure Out. When Im Flying Down The Freeway And I Start To Hit The Brakes It Makes A Loud Noise As If The Car Had Trumpet, It Does This When Im Pulling Out Of The Driveway. I Replaced The Master Cylinder And The Rear Brakes Dont Brake They Don't Budge At All. The Bleeding Has Been Done The Calipers Taken Apart And Put Back Together, Problem Still Lingers. Gentlemen I Know I Have Came To The Right Place For The Answer To My Problem. Thanks
