Principle and Maintenance Method of Auto Friction Brake Pad

Auto friction brake pads, also known as automobile brake skins, refer to the friction materials fixed on the brake drum or brake disc rotating with the wheel. In the automobile braking system, the auto brake pad is the most critical safety part, and the friction brake pad plays a decisive role in all braking effects. Therefore, a good auto friction brake pad is the protector of people and cars.

Structure of auto friction brake pads

The brake pad is generally composed of a steel plate, adhesive insulation layer, and friction block. The steel plate should be coated to prevent rust. During the coating process, a set-4 furnace temperature tracker is used to detect the temperature distribution to ensure quality.

The thermal insulation layer is composed of materials that do not transfer heat for thermal insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to produce friction, to achieve the purpose of vehicle deceleration and braking. Due to friction, the friction block will be worn gradually. Generally speaking, the auto friction brake pad with a lower cost will wear faster. After the friction materials are used, the brake pads should be replaced in time, otherwise, the steel plate will be in direct contact with the brake disc, which will eventually lose the braking effect and damage the brake disc.

Principle of auto friction brake pads

The working principle of the brake pad mainly comes from friction. The friction between the brake pad and the brake disc (drum) and the tire and the ground is used to convert the kinetic energy of the vehicle into heat energy after friction and stop the vehicle. A set of good and efficient braking systems must be able to provide stable, sufficient, and controllable braking force, and have good hydraulic transmission and heat dissipation capacity, to ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder and each sub cylinder, and avoid hydraulic failure and brake recession caused by high heat. The braking system on the car is divided into two categories: disc brake and drum brake, but in addition to the cost advantage, the efficiency of a drum brake is far less than that of a disc brake.

Maintenance method of auto friction brake pads

The brake pad is consumable and will gradually wear out in use. When it is worn to a limited position, it must be replaced, otherwise, it will reduce the braking effect and even cause safety accidents.

Under normal driving conditions, check the brake shoes every 5000 kilometers, not only check the remaining thickness but also check the wear state of the shoes, whether they wear degree of both sides is the same, whether the return is free, etc. if abnormal conditions are found, they must be dealt with immediately.
