Which type of testing is essential to verify the brake system’s functionality?

The brake effectiveness test and the leakage test are crucial for verifying the functionality of a brake system because they provide a comprehensive assessment of both the performance and integrity of the brake components.

The brake effectiveness test measures how well the braking system performs under operational conditions, ensuring that the brakes respond appropriately and provide the necessary stopping power. This test helps identify any issues with the brake system that could compromise safety during operation.

The leakage test checks for any loss of pressure within the brake lines and components, which can lead to failure in brake operation. Ensuring that the system is sealed and maintains the correct pressure is vital for reliable and safe braking performance.

Together, these tests offer a thorough examination of the brake system, ensuring it meets safety standards and functions as designed. Other options, such as visual inspections or sound tests, may identify some issues, but they do not provide the same level of detailed verification of performance and safety that the effectiveness and leakage tests can deliver.
