2000 Toyota Echo

CERTAIN PASSENGER VEHICLES HAVE THE POSSIBILITY THAT THE RECESS RETAINS A RUBBER SEAL RING, WHICH IS LOCATED AT THE END OF THE CYLINDER BODY, AND MAY BE CORRODED DUE TO AN IMPROPER WASHING PROCESS.

IN THIS CONDITION, BRAKE FLUID MAY LEAK FROM THE SEAL, OR A SMALL AMOUNT OF AIR MAY ENTER THE MASTER CYLINDER, WHICH COULD LEAD TO AN INCREASE OF VEHICLE STOPPING DISTANCE.

VEHICLE DESCRIPTION: PASSENGER VEHICLES ORIGINALLY SOLD OR CURRENTLY REGISTERED IN THE STATES OF ALASKA, COLORADO, IDAHO, ILLINOIS, IOWA, KANSAS, MAINE, MICHIGAN, MINNESOTA, MONTANA, NEBRASKA, NEVADA, NEW HAMPSHIRE, NEW YORK, NORTH DAKOTA, SOUTH DAKOTA, VERMONT, WISCONSIN, AND WYOMING. CONDENSED MOISTURE FROM THE POSITIVE CRANKCASE VENTILATION (PCV) PORT COULD SEEP TOWARD THE BRAKE VACUUM PORT INSIDE THE INTAKE MANIFOLD AND START TO FREEZE.

VACUUM ASSIST TO THE BRAKES WOULD BE DECREASED AND INCREASED PEDAL PRESSURE WOULD BE REQUIRED, INCREASING THE VEHICLE STOPPING DISTANCE.

VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH AN AUTOMATIC TRANSMISSION. DUE TO A UNIQUE COMBINATION OF CONDITIONS WHICH CONSIST OF COLD AMBIENT TEMPERATURES, LOAD APPLIED FROM AIR CONDITIONER AND OTHER ELECTRICAL DEVICES, AND IMMEDIATELY AFTER STARTING THE ENGINE, THERE IS A POSSIBILITY THAT THE VACUUM IN THE INTAKE MANIFOLD COULD BE INSUFFICIENT FOR THE BRAKE BOOSTER.

WHEN THE BRAKE IS APPLIED UNDER THIS COMBINATION OF CONDITIONS, VACUUM ASSIST TO THE BRAKES WOULD DECREASE, AND THE INCREASED PEDAL PRESSURE REQUIRED COULD LEAD TO AN INCREASE IN VEHICLE STOPPING DISTANCE.
