Classification of brake disc
The classification of the brake discs are disc brake and drum brake, and many of them are older car front coil after the drum, and now are disc brake, before and after the car a lot because of the drum brake heat dissipation is good, in the condition of high speed brake, it is not easy to produce hot recession, so its high-speed braking effect is good, but in the low speed of cold brake, the braking effect is inferior to drum brake, than the drum brake is expensive, so now a lot of senior car USES full brake, and ordinary car USES front coil after the drum, and relatively low speed, and the need of braking force big trucks, buses, still use drum brake.
1 disc brake disc is a round plate, the car is moving it is rotating, brake calipers is used to two pieces of clamping brake disc and produce braking force, it is relatively rotating brake disc is fixed, when you step on the brake is it clamping the brake disc to play a role of deceleration or parking.
