In order to increase the braking stability of vehicles at high speeds, disc brakes have become the mainstream of current braking systems. Because the disc of the disc brake system is exposed to the air, the disc has excellent heat dissipation. When the vehicle brakes suddenly at a high speed or brakes several times in a short time, the brake performance is less likely to decline. Better braking effect to improve vehicle safety.
How the disc brake works:
In simple terms, disc brakes use stationary brake discs to clamp the brake discs that rotate with the tires to generate friction and make the wheels turn slower.
When the brake pedal is depressed, the piston in the brake master cylinder will be pushed to build up pressure in the brake oil circuit. The pressure is transmitted to the piston of the brake wheel cylinder on the brake caliper via the brake fluid. When the piston of the brake wheel cylinder is under pressure, it will move outward and push the brake pads to clamp the brake disc, causing friction between the brake pads and the brake disc to reduce the wheel speed to slow down or stop the car.
Advantages of disc brakes:
1. Disc brakes have better heat dissipation than drum brakes, and they are less likely to cause brake degradation and brake failure when the brakes are continuously stepped on.
2. The disc brake system responds quickly and can do high-frequency braking actions.
3. The braking force of the left and right wheels of the disc brake is relatively even.
4. Because the brake disc has better drainage, it can reduce the situation of poor braking caused by water or sand.
5. The structure of the disc brake is simple and easy to maintain.
Disadvantages of disc brakes:
1. The braking force of disc brakes is low.
2. A brake disc with a larger diameter must be used, or the hydraulic pressure of the brake system must be increased to increase the braking force.
3. The parking brake device is not easy to install.
4. The wear of the brake pads is large, so the replacement frequency may be higher.
