SERVICE BRAKES
WHILE COMING TO AN INTERSECTION THE BRAKES WERE APPLIED AND THE PEDAL BECAME SOFT AND WHEN TO THE FLOOR, WITHOUT SLOWING THE VEHICLE DOWN. THE TRANSMISSION WAS SHIFTED INTO NEUTRAL AND THE EMERGENCY/PARKING BRAKE WAS APPLIED IMMEDIATELY IN ORDER TO STOP THE VEHICLE. THE VEHICLE WENT TO THE LOCAL DEALERSHIP WHERE THE DIAGNOSIS WAS A BRAKE LINE HAD RUPTURED DUE TO CORROSION (RUST) ON THE DRIVER SIDE REAR LINE. THE OTHER THREE LINES WERE IN A SIMILAR STATE AND HAD THE POTENTIAL TO FAIL AT ANY TIME. THERE WAS NO INDICATION ON THE MESSAGE CENTER THAT THERE WAS EVER INADEQUATE PRESSURE TO STOP THE VEHICLE WITH THE HYDRAULIC BRAKE SYSTEM EVEN WHEN IT WAS STEERED TO THE SIDE OF THE ROAD AND THE BRAKE PEDAL WAS APPLIED TO PUT THE TRANSMISSION INTO PARK. *TR
