Maintenance and service
& Recommended clutch fluid
Use one of the following types of fluid.
– Genuine SUBARU brake fluid
– FMVSS No. 116, fresh DOT 3 or DOT 4
brake fluid
CAUTION
Never use different brands of clutch
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even if
they are the same brand.
Brake booster
If the brake booster does not operate as
described in the following, 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 one 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
For vehicles equipped with the brake
assist system, when you depress the
brake pedal strongly or suddenly, the
following phenomena occur. However,
even though these occur, they do not
indicate any malfunctions, and the
brake assist system is operating prop-
11-29
erly.
. You might feel that the brake pedal
is applied by lighter force and generates a greater braking force.
. You might hear clicking (knocking)
sounds around brake pedal.
Brake assist is not a system that brings
more braking ability to the vehicle
beyond its breaking capability.
