The contact owns a 2007 Mercedes Benz GL450. The contact heard a squeaking noise when he depressed the brake pedal and the stopping distance increased. The dealer was unable to diagnose the cause of failure, however, they grinded the edges of the brake pads to reduce the squeaking noise. The speed was unknown. The failure mileage was 4,000 and current mileage was 6,600. The dealer recommended chamfering the brake pads to alleviate the noise. The dealer stated vehicle low on oil. Updated 09/2807
