What can occur if an air brake system is not properly maintained?

Answer: B — The risk of brake failure increases

If an air brake system is not properly maintained, the risk of brake failure increases significantly. This is due to various factors that may arise from lack of maintenance, such as air leaks, worn components, or insufficient air pressure. Over time, these issues can compromise the effectiveness of the braking system, leading to reduced stopping power or complete failure at critical moments. Regular inspections and maintenance help ensure that all components function as intended, preventing dangerous situations on the road. In addition to brake failure, unmaintained systems may also result in uneven wear of brake parts, which could lead to decreased braking performance and safety hazards. Maintenance is crucial to ensure reliability and effectiveness, making awareness of these risks vital for anyone operating vehicles equipped with air brake systems.
