Which statement correctly describes the braking power of the spring brakes?

The braking power of the spring brakes depends on the adjustment of the service brakes.

Spring brakes are a type of brake system used in air brake systems of commercial vehicles. They are designed to automatically engage and apply the brakes when there is a loss of air pressure in the system. The primary purpose of spring brakes is to ensure that the vehicle remains in a stopped or parked position even if there is an air system failure.

However, the braking power of the spring brakes is directly influenced by the adjustment of the service brakes. The service brakes, which are the primary braking system in the vehicle, need to be properly adjusted for optimal braking performance. If the service brakes are out of adjustment, it can impact the performance of the spring brakes.

When the service brakes are adjusted correctly, they provide the necessary stopping power and apply sufficient force to the spring brakes, ensuring their effective operation. On the other hand, if the service brakes are improperly adjusted, it can result in inadequate braking force being transmitted to the spring brakes, compromising their ability to hold the vehicle securely.
