What can excessive air leaks indicate in an air brake system?

Excessive air leaks in an air brake system are a significant indicator of poor maintenance practices. When there are air leaks present, it suggests that the system components—such as hoses, fittings, and seals—are not being properly maintained or replaced as necessary. Regular inspections and maintenance are essential to ensure that all parts are functioning as intended and to identify any wear and tear that could lead to leaks.

Identifying and addressing leaks promptly is vital because air leaks can compromise the effectiveness of the air brake system, leading to reduced braking power and increased stopping distances, which can create safety hazards. Proper maintenance practices would include routinely checking for leaks, tightening connections, and replacing any worn or damaged components to ensure the reliability and efficiency of the air brake system. Thus, observing excessive air leaks serves as a clear indicator that maintenance protocols are not being adequately followed.
