G37 Coupe V6-3.7L (VQ37VHR) (2008)
Vacuum Brake Booster: Initial Inspection and Diagnostic Overview
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 panel 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.
