OPERATION
With engine stopped, change vacuum to atmospheric pressure by
depressing brake pedal several times. Then with brake pedal fully
depressed, start engine and when vacuum pressure reaches the
standard, make sure that clearance between brake pedal and floor
panel decreases.
AIR TIGHT
• Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change vacuum to atmospheric pressure. Make sure that distance
at intervals of 5 seconds between brake pedal and floor panel
gradually increases.
• Depress brake pedal while engine is running, and stop engine with pedal depressed. The pedal stroke
should not change after holding pedal down for 30 seconds.

CAUTION:
• All hoses and piping (tubes) must be free from excessive bending, twisting and pulling.
• Make sure there is no interference with other parts when turning the steering wheel both clockwise
and counterclockwise.
• The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble the
parts. Replace applicable part with a new one, if necessary.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• Do not bend or twist brake hose sharply, or strongly pull it.
• When removing components, cover connections so that no dirt, dust, or other foreign matter gets in.
• Refill with new specified brake fluid. Refer to
MA-12, "Fluids and Lubricants"
.
• Do not reuse drained brake fluid.
