Classification of brake shoe blocks.

1. Cars can be divided into types through brake shoes: brake shoes for discs, brake shoes for drums, brake shoes for transporting large trucks, and so on.

2. Brake pads are mainly divided into the following categories: metal pads and carbon ceramic pads, metal pads are divided into less metal pads and semi metal pads, ceramic pads are divided into less metal pads, and carbon ceramic pads are used for carbon ceramic pads.

The braking principle of brake shoes.

The working principle of brake shoes mainly comes from friction. By utilizing the friction between the brake pads, brake discs, tires, and the ground, the kinetic energy of the car is converted into thermal energy after friction, enabling the car to stop. A good and effective braking system can provide stable, sufficient, and controllable braking force, and has good hydraulic transmission and heat dissipation capabilities. Ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted to the main cylinder and auxiliary pump, and avoid hydraulic failure and brake degradation caused by high heat.

Service life of brake shoes.

The replacement of brake shoes depends on how long your brake shoes have stayed in your car. If the driving distance exceeds 80000 kilometers, the brake shoes usually need to be replaced. However, if you hear the squeaking of the wheels, no matter how much mileage you run, you should replace the brake shoes. If you are not sure how many kilometers you have traveled, you may want to go to a free brake shoe replacement store, buy brake shoes from them, or go to a car service store to install them.

Inspection method for brake shoes.

1. Based on the thickness, the new brake shoe is generally around 1.5cm, and it will gradually become thinner after continuous friction during use. When the thickness of the brake shoe is only about one-third of its original thickness (about 0.5cm) when observed with the naked eye. Car owners will increase the frequency of self checks and be ready to replace them at any time. Due to the wheel hub design, some models do not have the conditions for visual observation and require tire disassembly to complete.

2. Listen to the sound, if the brake pedal is accompanied by the sound of iron friction or noise, immediately replace the brake shoes.

3. Based on foot feel, if it feels very difficult to step on it, it is often necessary to step on the brake deeper to achieve the previous braking effect, or if the pedal position is significantly low when emergency braking is applied, it is possible that the brake shoes have basically lost friction and need to be replaced.
