Jekit 380x32mm Brake Rotor Cast Iron Disc Type III Floating Bell

Generally, there are two kinds of brake discs: one is solid brake disc, which is equipped on minivans, and the other is ventilated disc brake disc, which is used in most models. This kind of brake disc also includes perforated brake disc and non perforated brake disc

Solid disc:
As the name suggests, a solid brake disc is a solid metal disc for braking, a solid metal disc!
This kind of disc is the most durable and strong one, but it has poor heat dissipation effect, easy to overheat and poor braking effect

ventilated disc brake:
Disc brake has the best heat dissipation! Because the holes on the working surface of the brake disc greatly enhance its heat dissipation and improve the cooling performance!
It can effectively reduce the braking noise! The small hole on the brake disc can remove the friction powder of the brake pad, reduce the side effects of the powder in the brake and reduce the brake noise!

The ventilation disc itself is a hollow disc. The only difference is that it has holes and no holes. The heat dissipation of the non hole ventilation disc is slightly poor, and the possibility of abnormal braking noise is also higher. Its biggest advantage is that its service life is longer than that with holes!

In terms of material requirements, the alloy materials used for perforated brake discs also have higher strength and more complex manufacturing process, so the price is also on the high side!

Here to remind you, when choosing brake pads, it is best to choose slightly softer brake pads or better ceramic pads. Although the service life is shorter, the braking effect is good and it is not easy to cause great wear to the brake disc!
The brake jitter in the later stage is the fault that the brake pads are too hard and the brake discs are seriously worn!

1. In terms of design principle, the purpose of the holes and scribed lines on the brake pad is to increase the surface area and friction direct ventilation, and to enhance the heat dissipation performance of the brake system and the drainage performance in rainy and snowy weather;

2. It can effectively improve the braking force. Of course, such products must use quality guaranteed brands produced by regular manufacturers. I think that in today's society, steering and braking are everyone's life;

3. Punching is better than scribing, because overheating of the brake disc will cause deformation, and the direction will shake. The perforated disc has good heat dissipation effect, so this problem will not occur. Theoretically, the maximum wear limit of the brake disc is 2mm, and a new brake disc must be replaced after use. However, in actual use, most car owners do not strictly implement this standard. The replacement frequency should also be measured according to their driving habits.
