The problem
THE HYDRAULIC STEEL BRAKE TUBE CONNECTING THE BRAKE HOSE TO THE LEFT OR RIGHT FRONT TOP WHEEL CYLINDER MAY DEVELOP A FRACTURE IN THE BEND NEXT TO THE WHEEL CYLINDER. THIS FRACTURE RESULTS FROM PERIODIC HIGH STRESSES IN THE TUBE DUE TO "BRAKE CHATTER" WHICH CAN OCCUR DURING CERTAIN ENVIRONMENTAL CONDITIONS.
What owners should do
THE DEALER WILL REPLACE THE FRONT BRAKE TUBES AT NO CHARGE TO OWNER.
