Jekit Double Rear Brake Caliper 380x28mm Disc For Tesla Model 3

Classification of brake discs
With the evolution of the automobile industry, there are fewer and fewer drum brakes. At present, it can only be seen in the rear brakes of some low-end cars. Most models adopt disc brake structure. The advantages of disc brake structure are more reflected in the process of frequent braking, better heat dissipation effect, so as to reduce braking heat attenuation

Our common brake discs are classified as follows
Solid disk
Ventilation disc
Perforated ventilation disc
Scribe vent disc
Floating ventilation disc
Ceramic ventilation disc

Among the most common mass production models, most are front ventilation plate and rear solid plate. It is also calibrated based on the first seven and the last three principles of braking strength. Most of the braking strength comes from the front braking system in the process of vehicle braking, so it is natural to adopt higher specifications in the front row

Floating brake disc
When buying a car, the brake disc configuration is often ignored. Most people see that as long as the front and rear disc brakes are good, but now many luxury brands have standard front floating brake discs

The advantage of floating brake disc is that the vehicle produces a large amount of calorific value in the process of high-intensity braking, which makes the physical phenomenon of thermal expansion and cold contraction of brake disc deform and affect the normal braking effect, which is also one of the main factors of heat attenuation. The floating brake disc is not directly locked with the central disc, or there is some small space between the floating part and the disc. After locking, the disc surface and the central disc still have a gap and can shake left and right, but the central disc and disc can be fixed. This design can solve the problem of overheating and shaking

Floating brake disc, compared with two-piece disc, has lighter weight and stronger braking stability
However, it should be noted that the structure of floating brake disc is relatively more complex and has higher Seiko standards, which can not be achieved by small workshops. So look for genuine products and don't try to be cheap

As the name suggests, the ventilated brake disc is ventilated and can play a better heat dissipation effect than the solid disc. The side of an ordinary ventilation disc is as flat as a solid disc. The ventilation holes can be seen in the longitudinal direction, and the structure inside is intricate and alternating, because it is necessary to ensure the heat flow and the rigidity of the brake disc at the same time

The main function of marking in the marking brake disc is to scrape off and discharge the brake powder worn by the brake pad through the marking groove, so as to minimize the impact on the brake friction

The main purpose of punching the perforated brake disc is to have a stronger heat dissipation effect. Higher intensity braking will lead to a sharp increase in the temperature of the brake disc, so more air flow is required for heat dissipation. The effect of ventilation disc alone can not be satisfied. Generally, when multi piston brake caliper is used, more efficient perforated ventilation disc is required
