Brake Accumulator Bottle - what is its function?

• A. Stores fuel.
• B. Provides electrical power.
• C. Stores hydraulic pressure for brakes in the event of total hydraulic loss.
• D. Maintains brake temperature.

Answer: (C)

The brake accumulator bottle is a pressure reservoir in the brake system that holds a precharged amount of hydraulic pressure. Its job is to provide a backup supply of brake pressure if the primary hydraulic system loses pressure—such as from a failed pump or a significant leak. When you press the brake, the stored pressure in the accumulator can be released to the brake lines, giving you braking power for a short time so you can slow down and stop safely while the system is repaired. It isn’t for storing fuel, supplying electrical power, or managing brake temperature.
