What is the effect of over-inflating the air brake system?

Answer: B — Increased risk of damage to components and possible brake failure

Over-inflating the air brake system can lead to an increased risk of damage to various components, which can ultimately result in brake failure. Air brakes function by using compressed air to activate the braking mechanism, and maintaining the correct air pressure is vital for their operation. Over-inflation can strain hoses, fittings, valves, and the air storage tanks, potentially causing leaks, ruptures, or other failures. This can greatly impair the braking system's performance, making it less reliable, and posing significant safety hazards. Improper inflation could also lead to issues such as inefficient brake application and uneven wear, which compromises the vehicle's braking effectiveness. In contrast, an appropriately maintained system will ensure optimal performance and responsive braking when needed.
