What occurs if air brake hoses are not properly maintained?

  1. No impact on vehicle safety

  2. Increased risk of failure due to cracks or leaks

  3. Higher fuel costs

  4. Better overall performance

The correct answer is: Increased risk of failure due to cracks or leaks

If air brake hoses are not properly maintained, they are susceptible to developing cracks or leaks. This deterioration can significantly compromise the integrity of the braking system, leading to reduced braking efficiency. When hoses develop leaks, air pressure can drop, resulting in insufficient force being applied to the brakes when required. This poses a direct danger to vehicle safety, as the ability to stop promptly may be impaired. Regular maintenance ensures that hoses are intact and functioning correctly, which is crucial to maintaining the overall safety and reliability of the braking system, especially in heavy-duty vehicles that rely heavily on air brakes.
