Low - end vehicle gucha has these advantages, in addition to the low cost

When consumers choose compact cars or small cars, people who are careful will find that different versions of the brakes are different between different versions. And after a sales person's brainwashing will come to a conclusion that the disc brake is much higher than the drum brake, drum brake is a synonym for the technology and low-end vehicles. So the drum brakes really are so fragile? Or is the drum brake really lower than the disc brake, as the consumer thinks? To talk about the disc brakes and the drum brakes.
The drum brake is the first brake system that appears on the vehicle, and its brake drum rotates with the wheels, with brake shoes and piston devices in the brake. When the brake is applied, the piston pushes the brake facings outward, producing friction with the inner wall of the brake drum to achieve a braking effect.
Advantages:
The braking force is large, and with the effect of automatic braking, so the general heavy vehicles use the drum brake. The brake drum used on the rear wheels of a small car is much smaller than the diameter of the brake disc, and the handbrake mechanism is easier to install, with a simpler structure and lower manufacturing costs.
Disadvantages:
Although the drum brake force is greater, but because the brake pad is located in the brake drum, the heat attenuation is obvious, the heat dissipation performance is poor, which affects the braking efficiency. Also the brake pedal force is not easy to control, it is difficult to achieve high frequency braking action. So if it is not for long continuous braking, the advantages of the drum brake are still some.
Disc brake
Disc brake is the most common brake on the market at present, is composed of brake disc and brake caliper, brake disc and wheel coaxial rotation, brake calipers are fixed. When the brake is used to set the oil pressure in the booster pump, friction between the brake lining and the brake disc is promoted through the brake tubing, thus achieving the braking effect.
Advantages:
Because the brake pad and brake disc are exposed in the air, the heat dissipation is better than the drum brake, the heat attenuation is small, and its reaction speed is fast, can achieve high frequency braking action, more accord with the demand of ABS system. In some poor road surface, its drainage is better, better anti - interference.
Disadvantages:
Without the automatic braking function of the drum brake, the brake force is relatively low. In order to get a better braking force, to increase the oil pressure or increase the contact area of the brake pad and brake disc, so the later modification to replace the larger brake disc or increase the number of pistons. In addition, the brake lining wear is larger, the replacement frequency may be higher.
Which is better?
Compared with two different types of brakes, disc brakes are more suitable for the needs of cars or SUVs in most cities. In the daily car, the load of the general front wheel is larger, the braking force needs more than the rear wheel, so the front wheel occupies the leading position, the rear wheel is only a auxiliary braking function. There is also the feeling of braking, the drum brake, regardless of the form of the linear degree, the brake pedal feel is relatively poor, like sitting in the way of the feeling, more stiff, the brakes are very bad. And the disc brake is much more linear, and more balanced, better travel texture, overall, the disc brake performance is better than the drum brakes.
So why is the rear wheel brake in different models of the same model different? That's the sensitive topic of price. Drum brakes are simple in structure, lower in manufacturing costs and cheaper in price. Take modern Junas as an example, with more than 8.89 vehicles equipped with disc brakes, and drum - type brakes as long as 7.39, although the configuration is more than that, but it is good to pull the price range of the starter model.
Conclusion: although the two types of brakes are all good, but also have their own disadvantages, for the average family car, there is not to be too much care about the four - roulette, the front coil drum type in contribute to appears comprehensive better, and the price is relatively cheap, for the general consumer will not feel too much, even the cost of cars will be lower.
