What could be a potential issue if the air compressor leaks?

1. Increased speed

2. Loss of braking effectiveness

3. Improved fuel efficiency

4. Increased engine power

The correct answer is: Loss of braking effectiveness

When an air compressor leaks, it can lead to a loss of braking effectiveness. The air braking system in commercial vehicles relies on compressed air to function properly. If there is a leak in the compressor, it will not generate and maintain the required air pressure needed to engage the brakes effectively. This can result in delays in braking response, reduced braking power, or even complete brake failure, which poses a significant safety risk while driving. On the other hand, increased speed, improved fuel efficiency, and increased engine power are not directly affected by an air compressor leak. In fact, a leaking compressor may lead to inefficiencies in the brake system, which could compromise the overall safety and performance of the vehicle rather than improve it. Understanding the critical role that the air compressor plays in maintaining brake system pressure highlights the importance of addressing any leaks promptly to ensure safe vehicle operation.
