Question

Quizplus · Accepted Answer

In a servo-type hydraulic drum brake, the shoes are not separately anchored at their heels; instead, one shoe's heel serves as the pivot point for the other shoe, creating a self-energizing effect in the direction of rotation. In a non-servo type brake system, the trailing shoe is energized in both forward and reverse directions, not only in reverse as stated.
