  1. With The Ignition Switch In Lock(O), Press The Brake Pedal Several Times To Deplete The Vacuum Reservoir, Then Press The Brake Pedal Hard, And Hold It For 15 Seconds. If The Brake Pedal Sinks, Either The Master Cylinder Is Bypassing Internally, Or The Brake System Is Leaking. Inspect The Brake Hoses And Lines (See brake Hose And Line Inspection ).
  2. Start The Engine With The Brake Pedal Pressed. If The Brake Pedal Sinks Slightly, The Vacuum Booster Is Operating Normally. If The Brake Pedal Height Does Not Vary, Do The Brake System Test (See brake System Inspection And Test ).
