Final Answer:
In a duo-servo drum brake system, the Anchor shoe end of the assembly is relatively free to move side-to-side. (option c)
Step-by-step explanation:
In a duo-servo drum brake system, the anchor shoe end of the assembly is relatively free to move side-to-side. This characteristic allows for the self-energizing effect in duo-servo brakes, where the movement of the anchor shoe contributes to increased braking force during application. Understanding the dynamics of duo-servo brakes is crucial for effective maintenance and troubleshooting in automotive braking systems.
The anchor shoe in a duo-servo drum brake system plays a pivotal role in the braking mechanism. As the brake shoes move outward during brake application, the anchor shoe, being relatively free to move side-to-side, contributes to the self-energizing effect. This effect enhances the braking force, making duo-servo brakes a common and effective design in many drum brake systems. The ability of the anchor shoe to move freely facilitates the mechanical advantage that amplifies the braking force during application.
Duo-servo drum brakes are widely used in various automotive applications, especially in rear-wheel braking systems. The design principles, including the movement of the anchor shoe, contribute to the overall efficiency and reliability of drum brake systems. The effective functioning of the anchor shoe in a duo-servo configuration demonstrates the engineering ingenuity applied to enhance braking performance and safety in automotive vehicles.(option c)
