Operation
Depress the brake pedal several times at 5-second intervals with the engine stopped. Start the engine with the brake pedal fully depressed. Check that
the clearance between brake pedal and dash lower pane decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the brake pedal is fully depressed. This is a normal phenomenon due to the brake
system operation.
Air Tight
-
Idle the engine for 1 minute to apply vacuum to the brake booster, and stop the engine. Then depress the brake pedal several times at 5-second
intervals until the accumulated vacuum is released to atmospheric pressure. Check that the clearance between brake pedal and dash lower panel
gradually increases (A to B to C) each time the brake pedal is depressed when performing this operation.
