Hello! 2000 brake discs at any time responding to demand, the 2000 brake discs at reasonable prices, the optimal product, best service. The braking currently have disc brakes and drum brakes, older vehicles are Qianpanhougu. The car now a lot of before and after the disc brake. Disc brake drum brake cooling, high-speed braking, not prone to heat fade, so its high-speed braking effect. However, in low-speed cold gate, the braking effect than drum brakes. The price is more expensive than the drum brake. So now, many high-class cars overall brake, while the average car uses Qianpanhougu, and relatively low-speed, large power trucks, buses and require the system still use drum brakes. Disc brake, brake disc is a round plate, the car moving when it is rotating. The brake caliper is used to the two grip brakes and braking force. It is the relative rotation of the brake disc is fixed. It grip the brakes when the brakes play a slow down or stop. The drum brake is sealed, shaped like a drum-like, in the country a lot of brake pot. While driving, it is rotating. Drum brake inside the fixed two arc-shaped or semicircular brake shoes. Brakes on the two brake shoes on wheel brake cylinder under the action of outside, propped up brake shoes rubbing against the inside wall of the brake drum to play a slow down or stop. 
 The advantages of the brakes: 
 1, disc brake cooling than the drum brakes good, continuous stampede braking does not cause the brake recession leaving brake failure. 
 2 brakes in the heat after the change of size is not to step on the brake pedal travel to increase. 
 The disc brake system, the reaction quickly, do the braking action of the high-frequency, and thus more in line with the needs of the ABS system. 
 4 disc brakes drum brakes of automatic brake tight around the wheel brake forces are relatively average. 
 5, due to better drainage of the brake disc, brake bad the situation can be reduced because of water or sediment. 
 6, compared with drum brakes, the brake simple structure and easy maintenance.
