Michigan CDL - Air Brakes Practice Exam

Question: 1 / 400

If you notice unusual brake pedal travel, what should you do?

Ignore it and continue driving

Investigate for air leaks or mechanical issues

Noticing unusual brake pedal travel is a critical indicator that there may be a problem with the braking system, which could compromise safety. Investigating for air leaks or mechanical issues is essential because it allows the driver to identify potential hazards. Air leaks in the brake system can lead to loss of braking power, which significantly increases the risk of an accident.

By thoroughly inspecting the system, the driver can determine if the brake lines, connections, or other components are functioning properly. This proactive approach ensures that any underlying issues are addressed before they lead to a failure while driving. In contrast, ignoring the problem or making adjustments without understanding the cause would not resolve the underlying issue and may exacerbate safety risks.
