What is a primary consequence of neglecting air brake maintenance?

Answer: B — Reduced brake effectiveness

Neglecting air brake maintenance leads to reduced brake effectiveness, which is a crucial safety concern. When air brakes are not properly maintained, components such as hoses, valves, and chambers can deteriorate or become obstructed, resulting in delayed response times and diminished stopping power. This can put both the operator and other road users at significant risk, as the reliability of braking systems is essential for safe vehicle operation. Regular maintenance ensures that the air brake system functions optimally, allowing for timely and effective stopping under various conditions.
