Vacuum Brake Booster: Testing and Inspection

NOTE:  Booster cannot be repaired, replace complete unit if necessary.

1. Depress brake pedal several times with engine not running, to relieve vacuum.
2. Depress and hold brake pedal while starting engine.
3. If booster function is OK, pedal will drop slightly as vacuum builds and boost takes effect.
