Advantages, Disadvantages and Application Scenarios of Brake Shoes
Advantages
Strong braking force: In the drum brake system, the brake shoes have a large contact area with the brake drum, making them particularly suitable for low-speed and heavy-duty vehicles (such as trucks and buses).
Low cost: With a simple structure, the manufacturing and maintenance costs of brake shoes are significantly lower than those of disc brakes, which makes them suitable for the rear wheel configuration of economical cars.
Integrated parking brake: The rear drum brakes are often integrated with a mechanical parking brake system, which directly controls the expansion of the brake shoes through a cable without the need for additional devices.
Disadvantages
Poor heat dissipation: The heat generated during braking is not easy to dissipate. Continuous braking may easily lead to a decrease in the friction coefficient (known as "heat fade"), which affects the reliability of braking.
Tedious maintenance: It is necessary to regularly adjust the gap between the brake shoes and the drum and clean the accumulated powder. After long-term use, brake noise is likely to occur.
