Car front brake disc action
The main function of the front brake disc of a car is to slow down or stop the vehicle through friction . When the driver presses the brake pedal, the piston in the brake master pump is pushed, creating pressure in the brake oil circuit. This pressure is transmitted through the brake fluid to the brake caliper, which in turn pushes the brake pad to clamp the brake disc. Friction between the brake pads and brake discs creates heat, which reduces wheel speed and slows or stops the vehicle .
Brake disc structure and material
Brake discs are usually made of a strong metal material, such as cast iron or steel, and are mounted next to the wheels. It is a round plate that also turns when the vehicle is moving .
The brake disc works in conjunction with the brake pads to brake by friction .
The difference between the front and rear brake discs
The front brake disc usually has a higher braking efficiency. In the process of vehicle driving, due to inertia, the vehicle will have a tendency to lean forward, the front brake system bears more than 70% of the braking force, the rear brake system is responsible for the remaining about 30%. Therefore, the front wheel plays a more critical role in the braking process, and the disc brake with higher braking efficiency and better heat dissipation performance becomes the ideal choice for the front brake .
automobile front brake disc is a key component in automobile brake system. Its main function is to generate braking force through friction to help the vehicle slow down or stop. The brake disc is usually a round metal disc that rotates in sync with the wheels. During braking, the brake calipers clamp the brake disc and generate braking force through friction to slow down or stop the vehicle .
Brake disc structure and function
The structure of the brake disc consists of a round metal disc body that rotates in sync with the wheel. When braking, the brake calipers clamp the brake disc and generate the necessary braking force through friction to enable the vehicle to slow down or stop.
Brake disc type and material
There are two types of brake disc: disc brake and drum brake. The disc brake is widely used in high-end models because of its excellent heat dissipation performance and high-speed braking effect, while the drum brake still occupies a place in low-speed heavy-duty vehicles because of its braking force and low cost. The brake disc material must meet strict standards, usually using gray cast iron 250(HT250) or the United States G3000 standard .
How the brake disc works
The working principle of the brake disc is to clamp the brake disc through the brake caliper, so that it produces friction with the brake pad, thus generating braking force. When the brake pedal is pressed, the brake caliper will tightly clamp the brake disc, so that the originally high-speed rotating brake disc gradually slows down, thereby reducing the speed of the wheel, so that the vehicle can stop. The process is similar to that of bicycle braking, where the brake skin presses against the rim of the wheel, stopping the wheel .
