G3000 TH250 Cast Iron Brake Disc Brake Rotor 380x34mm Slot Type

Jekit G3000 Brake Rotor 380x34mm Cast Iron Brake Disc For Many Car

Classification in manufacturing -- Standard for gray cast iron
In China's automobile market, brake discs are mainly four production standards. I won't talk about the niche production standard. Who are the four standards?
1. Germany GG20
2. Us G3000
3. China HT250
4. Japan fc200

Under the standard of gray cast iron, the most important additive in hot metal of brake disc is carbon manganese silicon matte phosphorus. Carbon should be the most important additive. He determines the hardness and friction of the brake disc! The more carbon, the softer the brake disc, and the better the braking performance. The less carbon, the harder the brake disc, and the worse the braking performance. However, nothing can be excessive. If there is too much carbon, the tensile properties will be reduced in gray cast iron, which is also unsafe

Introduction to automobile brake disc: function

The brake disc must be used for braking, and its braking force comes from the brake caliper. Generally speaking, the general brake caliper is fixed to the inner brake piston pump, and the outer side is a caliper structure. The inner brake pad is fixed to the piston pump, and the outer brake pad is fixed to the outer part of the caliper. The piston pushes the inner brake pad through the pressure from the brake oil pipe, At the same time, the caliper is pulled by the reaction force to make the outer brake pad inward. Both are pressed against the brake disc at the same time, and the braking force is generated through the friction between the brake disc and the inner and outer brake pads. In this process, the driving piston depends on the brake fluid, that is, hydraulic oil. This is assisted by the engine

For the hand brake, the cable is used to forcibly pull the brake pads through a lever structure mechanism to compress them with the brake disc, so as to generate braking force.

Effect and influence of punching and marking on brake disc.
Punching: it can increase heat dissipation and improve brake pad dust removal. The effect of powder discharge is far less than that of scribing. Most people will think that better heat dissipation can obtain better braking performance. It's right in theory. But in practice, it is not alone. In our daily driving, the brake discs and pads encounter a high temperature of about 300 degrees. If the mountain road goes downhill for a long time, we may reach a high temperature of about 600 degrees. More than 800 degrees is almost untouchable in our daily driving. Only those friends who race the track will need it. If you run at high speed, or track, or downhill, you step on the brakes crazily and frequently. Will make your disk temperature too high and heat dissipation too slow. In this case, it's not that your brake disc can't bear it, but that your ordinary brake pads can't bear it, and your original low dot standard brake oil can't bear it. The melting point of the brake disc is generally 1200 degrees. It is the most heat-resistant of the three products... Therefore, the punching technology has the smallest relationship and significance with the cars we use every day... It was born to meet the needs of high-end cars and racing cars. Not for civilian use... Maybe you will tell me that the heat dissipation of the brake disc is better and the temperature of the brake pad is lower. Yes, you're right! But how many people in our daily life step on the brake disc to more than 600 degrees? The punching heat dissipation of gray cast iron can be achieved by sacrificing friction performance. Isn't it safer?

Scribing: quickly remove the brake pad dust and improve the braking performance by 10% - 20% under the same cast iron standard. The principle is very simple. It eliminates the dust generated by the friction of the brake pad and reduces the lubrication caused by the dust. This increases the friction force. Increased braking performance is achieved. In practical application, the effect of GG20 and G3000 standard brake discs with more carbon is the most obvious after marking. In addition, for the brake disc with increased hardness and reduced carbon addition in order to ensure safety, the effect of scribing can be improved is very little.
