2009 SUBARU TRIBECA parking brake

BR-28
Brake Booster
BRAKE
Air tightness check
Start the engine, and idle it for 1 to 2 minutes, then
turn it OFF. Depress the brake pedal several times
applying the normal pedal force. The pedal stroke
should be the longest at the 1st depression, and it
should become shorter at each successive depres-
sion. If no change occurs in the pedal height when
pressed, the brake booster is faulty.
NOTE:
•In case of defective operation, inspect the condi-
tion of the check valve and vacuum hose as well.
•Replace them if faulty, and perform the test
again.
•If the defective condition is not improved, check
accurately using a gauge.
Operation check
1) While the engine is OFF, depress the brake ped-
al several times applying the same pedal force, to
check for a change in pedal height.
2) With the brake pedal pressed, start the engine.
3) As the engine starts, the brake pedal should
move slowly toward the floor. If the pedal height
does not change, the brake booster is faulty.
NOTE:
If faulty, perform an accurate check with a gauge.
Loaded air tightness check
Depress the brake pedal while the engine is run-
ning, and turn the engine OFF while the pedal is de-
pressed. Keep the pedal depressed for 30
seconds. If the pedal height does not change, the
function of brake booster is normal. If the pedal
height increases, it is faulty.
NOTE:
If faulty, perform an accurate check with a gauge.
2. OPERATION CHECK (WITH GAUGE)
CAUTION:
When checking operation, be sure to apply the
parking brake securely.
