Quizplus · Accepted Answer

The nitrogen-charged pneumatic accumulator in a hydraulic brake booster stores energy in the form of pressurized nitrogen gas. This stored energy is used to provide power assist for the braking system in the event that the engine stalls or if there is a loss of hydraulic pressure from the power steering pump, ensuring that the vehicle can still be stopped safely.
