“Trailing shoe” refers to a specific type of brake shoe used in drum brake systems. In this configuration, the friction surface of the shoe is designed to trail behind the shoe pivot point. When the brake is applied and the drum rotates, the trailing shoe is pushed away from the drum surface by the rotation, engaging the brake mechanism.
In British terminology, “trailing shoe” may also refer to what is known elsewhere as a “secondary shoe.” This secondary shoe is a component of a brake drum system where the activated end faces away from the approaching drum. As the drum rotates, the secondary shoe is forced into contact with the drum surface, providing additional braking force.
Both definitions emphasize the role of the trailing shoe or secondary shoe in engaging with the drum surface during braking, albeit in slightly different contexts depending on regional terminology.
