The problem
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THESE VEHICLES MAY HAVE A POORLY MANUFACTURED VACUUM CHECK VALVE IN THE VACUUM HOSE BETWEEN THE INTAKE MANIFOLD AND THE BRAKE VACUUM BOOSTER. WHEN THE BRAKE PEDAL IS DEPRESSED, THE VACUUM BOOSTER CHECK VALVE CAN STICK TO THE VALVE BODY.
Risk
THIS CONDITION WOULD RESULT IN REDUCTION OR LOSS OF VACUUM BOOST, REDUCING BRAKE EFFICIENCY.
What owners should do
DEALERS WILL REPLACE THE BRAKE VACUUM HOSE.
