Question

Quizplus · Accepted Answer

The return spring is the component responsible for returning the diaphragm and power piston to their unapplied position when brakes are released. Residual vacuum and atmospheric pressure help maintain braking force when the brakes are applied but do not play a role in releasing the brakes. Tension may be a factor in holding the diaphragm in place, but it is not the primary mechanism for returning it to its unapplied position.
