BRAKE SYSTEM
PRECAUTION
1. Necessary care must be taken to replace each part
properly as it could affect the brake system
performance. This could cause driving hazards.
Replace each part with an identical part with the
same number.
2. It is very important to keep parts and the area clean
when repairing the brake system.
3. If the vehicle is equipped with a mobile
communication system, refer to the precautions in
the INTRODUCTION section.

ON-VEHICLE INSPECTION
1. INSPECT BRAKE BOOSTER
(a) Check the air tightness.
(1) Start the engine and stop it after 1 or 2 minutes.
Depress the brake pedal several times slowly.
HINT:
• If the pedal can be depressed to the floor on
the 1st time, but cannot be depressed as far
on the 2nd or 3rd times, the booster is
airtight. If not, inspect the vacuum check
valve.
• If the vacuum check valve is normal, replace
the brake booster assembly.
(2) Depress the brake pedal while the engine is
running, and stop the engine with the pedal
depressed.
HINT:
• If there is no change in the pedal reserve
distance after holding the pedal for 30
seconds, the booster is airtight. If not,
inspect the vacuum check valve.
• If the vacuum check valve is normal, replace
the brake booster assembly.
(b) Check the operation.
(1) Depress the brake pedal several times with the
engine stopped and check that there is no
change in the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
• If the pedal goes down slightly, the operation
is normal. If not, inspect the vacuum check
valve.
• If the vacuum check valve is normal, replace
the brake booster assembly.
