Question

Quizplus · Accepted Answer

Spring brake chambers are designed to provide parking and emergency braking functions. They can deliver a significant amount of force, but typically, this force is about half that of a full service (pneumatic) brake application. This is because the spring brake is primarily designed for holding a vehicle stationary and providing emergency braking rather than the more variable control offered by service brakes.
