The brake shoe is an important part of the automobile brake system, which directly affects the safety performance of the vehicle. This article will explain in detail the working principle, common types and key points of replacement and maintenance of brake shoes to help car owners better understand this key component and ensure driving safety.

The importance and working principle of brake shoes

Brake shoes play a vital role in the automotive brake system. When the driver steps on the brake pedal, the brake fluid will push the brake caliper to clamp the brake disc, thereby slowing the wheels. In this process, the brake shoe plays a key role in transmitting braking force. Brake shoes usually work in conjunction with brake discs and brake pads to ensure that the vehicle can stop smoothly and reliably.

Through diagrams and animations, we can more intuitively understand how the brake shoes work. When the brake shoe is under pressure, it will press tightly on the brake disc, generating friction, thereby slowing down the speed. This process requires precise coordination and efficient materials to ensure that each brake can achieve the desired effect.

Therefore, the state of the brake shoe directly affects the braking performance of the vehicle, which in turn is related to the safety of the driver. Regular inspection and maintenance of brake shoes is one of the important measures to ensure driving safety.

Common types of brake shoes

There are two main types of brake shoes: drum brake shoes and disc brake shoes. These two types have their own advantages and disadvantages, and are suitable for different models and usage scenarios.

• Drum brake shoes: Drum brake shoes are mainly used in old models and some modern commercial vehicles. Its advantages are simple structure and low cost, but the disadvantage is that the heat dissipation performance is poor, and it is easy to overheat and cause the braking force to decrease.
• Disc brake shoes: Disc brake shoes are widely used in modern passenger cars. Its advantages are good heat dissipation performance, fast response speed, and ability to provide stable braking force at high speeds. However, the cost of disc brake systems is relatively high.

To choose the appropriate brake shoe type, you need to consider the specific situation of the vehicle and personal needs. If you often drive on urban roads, disc brake shoes may be a better choice; and in rural or mountainous areas, drum brake shoes also have their own applicable scenarios.

How to judge whether the brake shoe needs to be replaced

To judge whether the brake shoe needs to be replaced, you can use the following simple and easy methods:

1. Listen to the sound: If you hear an abnormal sharp sound when braking, it may be that the brake shoes are severely worn or foreign objects are stuck.
2. Observe the thickness: Generally speaking, the minimum thickness of the brake shoe should not be less than 3mm. If the thickness of the brake shoe is found to be close to or below this value, it needs to be replaced in time.
3. Check the surface condition: If there are obvious cracks or uneven wear on the surface of the brake shoe, it also needs to be replaced.

Through actual cases and user experience, it can help car owners to judge the status of brake shoes more accurately. For example, during a long-distance self-driving tour, a car owner failed to replace the severely worn brake shoes in time, resulting in a brake failure in an emergency and almost an accident. This reminds us once again of the importance of checking brake shoes regularly.

Correct installation procedure of brake shoe

Replacing the brake shoes is a relatively simple maintenance task, and the owner can complete it at home. The following are the detailed replacement steps:

1. Preparation: Prepare a basic set of maintenance tools, such as wrenches, screwdrivers, jacks, etc.
2. Lift the vehicle: Use a jack to lift the vehicle, making sure that the tires are off the ground.
3. Remove the old brake shoes: Loosen the bolts that fix the brake shoes, and carefully remove the old brake shoes.
4. Install new brake shoes: Put the new brake shoes back in place, ensuring that all parts are tightly connected.
5. Adjust the gap: Adjust the gap between the brake shoe and the brake disc to ensure that the brake can work normally.
6. Test the brake: In the case of low-speed driving, lightly step on the brake several times to confirm the normal operation of the brake system.

Through the detailed graphic tutorial, you can ensure that every link can be clear. If you are not sure about a step, you can also consult professional maintenance personnel.

Daily maintenance and maintenance of brake shoes

In order to extend the service life of the brake shoes and reduce the probability of failure, car owners need to pay attention to the following daily maintenance and maintenance points:

1. Regular inspection: Every time you maintain, carefully check the wear of the brake shoes.
2. Cleaning and maintenance: Regularly clean the dust and dirt on the brake shoes and keep the surface clean.
3. Lubrication treatment: Properly lubricate the sliding parts of the brake shoes to reduce wear.
4. Reasonable use: Avoid long-term continuous heavy braking to avoid excessive wear of the brake shoes.

Although these tips are simple, they can greatly extend the service life of the brake shoes and ensure driving safety.

Choose the brand recommend of high-quality brake shoes

There are many well-known brake shoe brands on the market, and it is important to choose a brand with reliable quality. Here are some brands worth recommend:

• BOSCH (Bosch): BOSCH is a world-renowned auto parts manufacturer with stable quality and excellent performance of brake shoes.
• FEBI (Feibi): FEBI is a German brand, and its brake shoe products enjoy a high reputation in the European market.
• TRW
