The problem
THE POSSIBILITY EXISTS THAT UNDER HIGH AMBIENT/UNDERHOOD TEMPERATURES, A CHEMICAL ACTION MAY TAKE PLACE BETWEEN ANY WATER CONTENT IN THE BRAKE FLUID AND THE BRAKE SPRING IN THE MASTER CYLINDER SECONDARY PISTON CHAMBER. AS A RESULT OF THIS CHEMICAL ACTION, A GAS DEVELOPS (HYDROGEN) WHICH DISPLACES THE BRAKE FLUID CAUSING A PROGRESSIVE INCREASE IN BRAKE MASTER CYLINDER PISTON TRAVEL WITH SUBSEQUENT DECREASE IN THE EFFICIENCY OF THE REAR BRAKING SYSTEM.
What owners should do
THE DEALER WILL REPLACE THE BRAKE MASTER CYLINDER ON THE INVOLVED VEHICLES AT NO CHARGE TO OWNER.
