Is the car brake drum disc brake or drum brake good? Remember learning to drive when the master told Xiao Bian a sentence, "driving well is not to see how you step on the gas, but how you step on the brake. " From that day Xiao Bian knew the importance of the brake. With the continuous understanding of vehicles, it is found that the brake is indeed not simple. Taking the type of brake as an example, it can be divided into disc brake and drum brake. It is believed that many car owners or prospective car owners are not particularly clear about the advantages and disadvantages of these two types of brakes, i'M GONNA talk to everybody today. Car Brakes also known as the car brake, simply put through the friction of the brake pads will be kinetic energy into heat, so that the car lost kinetic energy and stop down. But the friction will produce a lot of heat, so the heat dissipation and heat resistance of the brake directly determines the quality and durability of the brake, disk brake is better than drum brake. From the structural point of view disc brake is more complex than drum brake structure, it is controlled by hydraulic, the main parts have brake disc, sub-pump, brake Caliper, tubing and so on. DISC brakes are generally made of alloy steel and are fixed to the wheels so that they can be turned with them. Two brake pads on the brake calipers are mounted on either side of the disc, so that when the brake is applied the hydraulic action is transmitted through the Piston of the tripper pump, causing the brake pads to brake as if they were gripping a rotating disc to stop the vehicle. The main advantage of this design is that the brakes are faster and more responsive, and because the disc brakes are exposed to the air, they dissipate heat better, especially the ventilated disc brakes that became popular in the last two years. But the complexity of the design is a cost increase, so the use of disc brakes in the past are basically medium-to-high-grade cars. The drum brake, shaped like a tambourine of cast iron, is fixed to the tire and rotates at the same speed. To hold a vehicle to a stop is to hold it to a stop like a hand on a spinning tire. Relatively simple structure, the cost is also relatively low, and from the brake strength point of view, in fact, drum brake disc brake than a little bit larger. Therefore, in many buses, trucks and trucks or the use of drum brake braking, but the sensitivity of the disk brake than a lot of poor, low cost. So a few years ago we often saw a lot of cars or suvs using front and rear drum brake combination, both to take the advantages of both sides to ensure safety. The biggest problem of drum brake is actually the heat dissipation, which is not conducive to long-term driving. In addition, under the influence of high temperature, drum brake is prone to extremely complicated deformation, brake recession and vibration, resulting in a decrease in brake efficiency, even set the wheels on fire, creating a safety hazard. Therefore, the combination of front and back drum is also becoming less and less. Generally speaking, in addition to the cost and strength, the brake disc is better than the drum brake in all other aspects, especially its stability and heat resistance is not comparable to the brake drum, and now most of the vehicles are starting to use disc brake, there is no need to struggle too much, Xiao bian feel need to struggle or use ordinary disc or ventilation disc, hope to help everyone.
