“The contact owns a 2004 mercedes benz C240. The contact stated that while driving approximately 40 MPH, the brakes malfunctioned causing the brake pedal to sink into the floor creating an extended braking distance. The failure nearly caused the vehicle to crash into the rear of a second vehicle. The vehicle was taken to an independent mechanic. The technician diagnosed that the brake lines were corroded causing brake fluid to leak from the vehicle. No further information was available.
