Question

In a leading/trailing drum brake system, where are the return springs positioned?

a) Between the shoes
b) On the backing plate
c) On the wheel cylinder
d) On the brake drum

Answer 1

In a leading/trailing drum brake system, the return springs are positioned between the brake shoes to pull them away from the drum when not in use.

Step-by-step explanation:

In a leading/trailing drum brake system, the return springs are positioned between the shoes. The primary function of these springs is to pull the brake shoes away from the drum's surface when the brakes are not being applied. This prevents the shoes from dragging along the drum, which would cause excessive wear and potential brake drag, leading to reduced efficiency and increased fuel consumption. The springs ensure the proper retraction of the shoes and allow for the correct functioning of the brakes.
