Post-installation check
Checking functionality
Press the brake pedal several times at 5-second intervals with the engine off. Then, press the brake pedal all the way down and start the engine. Make sure that the gap between the brake pedal and the floor panel decreases.
Note: When you press the brake pedal all the way down, you may feel a slight bump with a small click. This is normal and is due to the operation of the brake system.
Checking for leaks
- Start the engine and let it run at idle for about 1 minute, applying vacuum to the booster. Stop the engine. Then press the brake pedal several times at 5-second intervals with normal force and release the existing vacuum. Make sure that when you press the brake pedal, the gap between the brake pedal and the floor panel gradually increases (A → B → C).
- Press the brake pedal with the engine running and turn off the engine with the pedal depressed. Keep the pedal depressed for about 30 seconds and make sure that the pedal travel does not change.
Note: When you press the brake pedal all the way down, you may feel a slight bump with a small click. This is normal and is due to the operation of the brake system.
