How is the replacement cycle of BRAKE SHOE SERIES related to the use of the vehicle and the material of the brake shoes?

The replacement cycle of brake shoes is closely related to the use of the vehicle and the material of the brake shoes. A correct understanding of these two factors is essential to ensure the efficiency of the brake system and the safety of the vehicle. The following details how these two factors affect the replacement cycle of brake shoes.

The vehicle's use environment, driving habits and driving conditions will affect the wear rate of brake shoes. Here are some of the main factors:
If the driver is accustomed to frequent sudden braking (such as in city driving or traffic jams), the wear of brake shoes will be accelerated. When braking suddenly, the friction between the brake shoes and the brake drum is very large, causing the friction material to wear quickly.
In contrast, smooth driving and gradual braking can reduce the wear of brake shoes, thereby extending the service life of brake shoes.
In city driving, vehicles often face more frequent stops and starts, and the brake shoes need to work frequently, which will cause the brake shoes to wear faster. Especially in urban areas with heavy traffic, frequent braking actions will increase the wear rate of brake shoes.
Driving on highways is usually smoother and the braking frequency is lower, so the wear of brake shoes is relatively slow. For vehicles driven in this way, the replacement cycle of brake shoes is usually longer.
In mountainous areas or when heavy objects need to be carried, the brake system is under greater burden, the brake shoes will be under greater pressure and wear faster. Therefore, vehicles that often drive in these environments need to check and replace brake shoes more frequently.
If the vehicle is often driven in a wet or slippery environment, the friction performance of the brake shoes may be affected, causing them to wear faster.
Dusty environments increase the friction between the brake shoes and the brake drum, resulting in accelerated wear of the friction material.

In ice, snow or heavy rain, the brake system has a greater workload, which may also cause the brake shoes to wear faster.
The material of the brake shoe directly determines its wear resistance, high temperature resistance and service life. Brake shoes of different materials have different performance characteristics, which in turn affect their replacement cycle.
Organic brake shoes are a mixture of resin, rubber, fiber and other chemical components, and are generally suitable for light vehicles and urban traffic. The advantages are:
Organic brake shoes are relatively quiet and produce less noise when braking.
Because the friction coefficient is relatively stable, it provides a more comfortable driving experience.
However, organic friction materials have poor high temperature resistance and low wear resistance, so they wear out faster when used under heavy load or high temperature environment. This makes the replacement cycle of organic brake shoes usually short, especially in city driving with frequent braking.
Semi-metallic brake shoes are made of metal powder (such as copper, iron, etc.) mixed with other ingredients, and have better high temperature resistance and wear resistance. Their characteristics include:
Semi-metallic friction materials have a high friction coefficient and obvious braking effect, which are suitable for heavy vehicles or high-performance vehicles.
Semi-metallic friction materials are more stable in high temperature environment and are not prone to brake failure due to overheating.
Due to the high wear resistance and high temperature resistance of semi-metallic brake shoes, they are generally suitable for vehicles with heavy loads and can extend the replacement cycle. However, semi-metallic brake shoes are relatively noisy and may cause greater wear on the brake drum, especially under high-load driving conditions.
Ceramic brake shoes are made of ceramic fibers mixed with other materials (such as resin, metal, etc.) and have the following characteristics:
Ceramic brake shoes have very good wear resistance and can maintain good performance even in high temperature environment.
Ceramic materials can significantly reduce noise and dust during braking, providing a smoother braking experience.
Ceramic materials have better high-temperature resistance than organic and semi-metallic materials, and are suitable for high-performance and high-load brake systems.
Due to their excellent wear resistance and high-temperature resistance, ceramic brake shoes usually have a longer replacement cycle and are suitable for long-term use without frequent replacement. Although their price is higher, the long replacement cycle may actually reduce the long-term use cost.

Regularly checking the status of brake shoes to ensure the safety and stability of the brake system is a maintenance task that every car owner needs to pay attention to.
