The braking power of spring brakes is affected by the adjustment of which component?

• A. Service brakes
• B. Battery
• C. Windshield wipers
• D. Fuel gauge

Answer: (A)

The spring brakes’ braking power depends on the air pressure controlled by the service brake system. If the service brakes are not properly adjusted, the amount of air pressure available to release or modulate the spring brakes can be off, which changes how much braking force the spring brakes can apply. In other words, proper adjustment of the service brakes directly affects how effectively the spring brakes can stop the vehicle. The other components listed—battery, windshield wipers, and fuel gauge—do not influence the spring brakes’ braking force.
