- If the pedal force and fluid pressure correlation is within the specification with the engine stopped and a vacuum amount of 0 kPa {0 mmHg, 0 inHg}
, the system is normal.

- Start the engine and depress the brake pedal when the vacuum reaches 66.7 kPa {500 mmHg, 19.7 inHg} .
- At this time, apply the indicated pedal force and if the fluid pressure is within the specification, the unit is normal.
