Brake booster
S11AQ
If the brake booster does not operate as
described in the following procedure, we
recommend that you have it checked by
your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal sh ould move
slightly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for
approximately 1 minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake
booster operates properly if the pe dal
stroke decreases with each depression.
NOTE
For models equipped with the brake
assist system, when you depress the
brake pedal strongly or suddenly, the
following phenomena occur. They do
not indicate any malfunctions, and the
brake assist system is operating prop-
erly.
. You might feel that the brake pedal
is applied by lighter force and gener-
ates a greater braking force.
. You might hear the sound of ABS
operating from the engine compart-
ment.
