Q: What Is the Maintenance and Operating Check for a Power Brake Booster Unit?
A: Periodically inspect the vacuum hose and case. To check operation, depress the pedal with engine off and start engine. To check airtightness, start engine and turn off after one or two minutes. To remove, disconnect vacuum hose, disconnect push rod, remove nuts, and lift away. To install, place in position, tighten nuts, connect push rod, install master cylinder, connect vacuum hose, and bleed brake system. Test brakes before normal operation.
