What is the difference between a car disc brake and a gucha? If the disc brakes are better than gucha, why do you have a car with gucha?

You can't use a " good" or " bad" word to deny a configuration, they develop to today still exist in the world, must have their significance. Now car buyers often think that the disc brakes, especially the ventilation disc is the high-end choice, it seems that the drum brake is the evil, there is no significance, in fact, the drum brake has not been eliminated from the car industry is for a reason!
The drum type drum has its own advantages, and has a monopoly of one side
Drum brakes -
The drum brake is extruded from the inside out, and the brake shoe and the brake drum form a large area of friction, resulting in braking force.
Disc brakes -
The friction of the disc brake depends on the caliper clamp.
From this, you see:
1. the drum friction area is larger,
2. brake form is easy to be magnified - after the expansion of the brake drum, the reaction force produced by the wheel continues to rotate as " holding the dead ", which distorts the brake drum and produces a greater braking force.
In conclusion, the braking efficiency of gucha is higher.
3. gucha is simple in structure, low in cost, easy to damage and easy to repair.
So, now from the light truck to the medium - sized, still be monopolized by the gucha! In particular, large trucks will use the air compressor to increase the air pressure to expand the braking force, the device must be combined with the gucha ( as if the implementation of esp must be based on the four wheel disc, they are interdependent ), these are closely related to the braking effect, and there is no relationship, so do not connect the simple and low end of the gucha. Since the elimination of gucha is not the money, it is not a matter of time.
Since gucha is so good, why does the disk brake occupy the car and the SUV market?
Gucha's disadvantages are also obvious, compared to disk brake, poor ride comfort, poor ride comfort, poor thermal performance ( trucks used in mountain and hill areas, long downhill brakes often use water to cool, otherwise attenuation can be severely damaged ), thermal decay, poor drainage, and the most important point mentioned above - not to realize the vehicle initiative safety with the electronic control system: esp requirements must be built on the basis of the four roulette brake!
Therefore, in the light of car and SUV, the braking ability of the disc brakes can meet the need, and has so many advantages, naturally occupy the high-end and mid-range model market, and the low-end models are limited to the cost, not to form a monopoly, but the cost problems with large-scale production will gradually be solved, future disc brakes will gradually become the only choice in the field of small cars; Just like gucha will still be the only choice for trucks; In the area of pickup and MPV, depending on the size of the model, the quality of conditioning, positioning ( home positioning or pure goods ), different manufacturers have different choices.
