2006 SUBARU IMPREZA stop start

Maintenance and service 11-27
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 slight-
ly 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 ap-
proximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake boost-
er operates properly if the pedal stroke de-
creases with each depression.
Brake pedal
Check the brake pedal free play and re-
serve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet ”.
Checking the brake pedal free
play
1) 0.04 – 0.12 in (1.0 – 3.0 mm)
Stop the engine and firmly depress the
brake pedal several times. Lightly press
the brake pedal down with one finger to
check the free play with a force of less
than 2 lbs (10 N, 1 kg).
If the free play is not within proper specifi-
cation, contact your SUBARU dealer.
Checking the brake pedal re-
serve distance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approxi-
mately 66 lbs (294 N, 30 kg) and measure
the distance between the upper surface of
the pedal pad and the floor.
When the measurement is smaller than
the specification, or when the pedal does
not operate smoothly, contact with your
SUBARU dealer.1
