Whether you are a car maintenance technician or an ordinary car owner, understanding the relevant knowledge of brake shoes will help ensure driving safety and extend the service life of the vehicle.

What is the brake shoe?

The brake shoe is an important part of the vehicle brake system, usually located in the drum brake system inside the wheel. Its main function is to decelerate or stop the rotation of the wheels through friction when the brake pedal is stepped on, thereby realizing the braking of the vehicle. Brake shoes are generally composed of a metal matrix and friction material, and their shape is similar to that of a horse shoe, hence the name.

The importance of brake shoes

Brake shoes play a vital role in ensuring driving safety. Good brake shoes can effectively shorten the braking distance and reduce the probability of accidents. For example, according to statistics, when a car with a speed of 100 kilometers per hour brakes in an emergency, if the brake shoes are severely worn, the braking distance may increase by more than 10 meters, which is a huge hidden danger for driving safety. Therefore, regular inspection and replacement of brake shoes is very necessary.

Types and materials of brake shoes

The common brake shoes on the market mainly include metal composite materials and ceramic materials. Metal composite brake shoes have high heat resistance and wear resistance, and are suitable for most passenger cars and commercial vehicles. Ceramic brake shoes are known for their low noise, light weight and long service life, and are more suitable for high-end models. Each material has its own unique advantages and applicable scenarios, and it is very important to choose the brake shoe that suits you.

How to judge whether the brake shoe needs to be replaced

There are many ways to determine whether the brake shoes need to be replaced. The first is to listen to the sound. If you hear a sharp metal sound when braking, it may be that the brake shoes have worn to the limit. The second is to observe the thickness. Generally speaking, the minimum thickness of the brake shoe should not be less than 3mm. Finally, feel the braking effect. If you find that the brake response is slow or the braking force is significantly weakened, you should also check the condition of the brake shoe in time. Through these methods, we can help you find problems in time and take corresponding measures.

Points for selecting high-quality brake shoes

When choosing brake shoes, there are several key factors to consider. The first is the brand, the choice of well-known brands of brake shoes is more secure.
