ON-VEHICLE INSPECTION

1. INSPECT BRAKE BOOSTER

1. Depress the brake pedal several times with the engine off and check that there is no change in

the pedal reserve distance.

2. Depress the brake pedal and start the engine. If the pedal goes down slightly, operation is

normal.

b. AIR TIGHTNESS CHECK

1. Start the engine and stop it after 1 or 2 minutes. Depress the brake pedal several times

slowly. If the pedal goes down farthest the 1st time, but gradually rises after the 2nd or 3rd
time, the booster is airtight.

2. Depress the brake pedal while the engine is running, and stop the engine with the pedal

depressed. If there is no change in the pedal reserve travel after holding the pedal for 30
seconds, the booster is airtight.
