Anti-Lock Brake System (Service Information): Sensor-Travel: Removal

CAUTION: Vacuum in power brake booster must be pumped down (removed) before removing master cylinder from power brake booster. This is necessary to prevent power brake booster from sucking in any contamination as master cylinder is removed. This can be done simply by pumping brake pedal, with vehicle's engine not running, until a firm feeling brake pedal is achieved.

With engine not running, pump brake pedal until a firm pedal is achieved (4-5 strokes).
