What should you do if you notice a leak in the air brake system while driving?

• A. Stop safely and inspect for leaks; do not continue until repaired.
• B. Increase speed to reach the next service area.
• C. Ignore and continue driving.
• D. Release the brake to reduce pressure.

Answer: (A)

Air brake systems rely on maintaining sufficient air pressure to apply the brakes, so a leak threatens your ability to stop. If you notice a leak while driving, stop safely as soon as you can and inspect the system for leaks rather than continuing to drive. Continuing to operate with a leak can lead to reduced braking power or complete brake failure, which is extremely dangerous. After stopping, set the parking brake, chock the wheels if possible, and check the air gauges and lines for damage or loose connections. If you can’t locate or repair the leak quickly, don’t drive the vehicle until it has been repaired by a qualified mechanic. This approach protects you and others from a potentially dangerous loss of braking while in traffic.
