a. Start the motor, and shut it down after one or two minutes,
then step on the pedal several times slowly.
Tips:
If the pedal goes down greatly at the first step, but it gradually
goes up after the second and third steps, it means the air
tightness is good.Brake System -Vacuum Booster4-92 b. When the motor is running, step down the brake pedal, and then shut down the motor.

If the reserved distance does not change thirty seconds after
the pedal is stepped down, it means the air tightness is good.
(2) Operation check
a. When the ignition switch stays in OFF position, step on the
pedal several times, and then check that the reserved
distance should not change.
