Question

Quizplus · Accepted Answer

In a duo-servo brake system, the front shoe is indeed referred to as the primary shoe because it is the first to contact the drum during forward motion, and the rear shoe is the secondary shoe, which receives additional force from the primary shoe. In a non-servo brake system, the terms leading and trailing shoe are used to describe the front and rear shoes, respectively, based on their position and function during braking. Therefore, both Technician A and Technician B are correct.
