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 1 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 models 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 properly.

- You might feel that the brake pedal is applied by lighter force and generates a greater braking force.

- You might hear the sound of ABS operating from the engine compartment.

Brake assist is not a system that brings more braking ability to the vehicle beyond its breaking capability.
