What is a common cause of failure in parking brake systems?

• A. Overheating of the engine
• B. Corrosion in the air lines
• C. Fatigue in the tires
• D. Excessive fuel consumption

Answer: (B)

A common cause of failure in parking brake systems is indeed corrosion in the air lines. In vehicles equipped with air brake systems, the parking brake relies on compressed air to engage and disengage. If there is corrosion within the air lines, it can lead to leaks or blockages, resulting in a failure to build or maintain the necessary pressure required for the parking brake to function properly. This prevents the system from achieving the level of force needed to keep the vehicle stationary, especially on inclines. Regular inspection and maintenance of the air lines are crucial to ensure the integrity of the parking brake system and to prevent any potential failure due to corrosion.
