Brake booster

If the brake booster does not operate as
described in the following procedure, 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 should 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 pedal
stroke decreases with each depression.
NOTE
When you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-
cate any malfunctions, and the brake
assist system is operating properly.
. 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.
Brake assist is not a system that brings
more braking ability to the vehicle
beyond its breaking capability.
