Durable Internally Vented Brake Disc for Enhanced Stopping Power

The holes on the ventilation disc are mainly used as ventilation holes to help cool the brake disc, which can accelerate ventilation and heat dissipation, improve braking efficiency, and at the same time, it can also suppress braking noise, reduce weight, clean and exhaust.

The ventilated disc has a unique structure. Its interior is hollow and has numerous holes. When the car is in motion, the centrifugal force causes the air to flow through the holes, forming convection, which quickly takes away the heat generated by braking. However, the solid disc does not have such channels for air convection. Its heat dissipation mainly relies on the heat conduction of the disc itself, so its heat dissipation effect is not as good as that of the ventilated disc.

Generally speaking, the service life of ventilation discs is longer than that of solid discs. Because the excellent heat dissipation performance of the ventilated disc can reduce the wear and performance decline of the brake disc caused by high temperatures, under normal usage conditions, the ventilated disc can be used for a longer time.

For most ordinary front-wheel drive cars, braking mainly relies on the front wheel brake discs, with the rear wheel brakes playing an auxiliary role. The rear wheels have less braking force and generate less heat, and ordinary brake discs are sufficient to handle it. In addition, ventilated discs are expensive. To cut costs, many vehicles do not use ventilated discs on the rear wheels.

Solid discs are mainly used for the rear wheels, while ventilated discs can be used for all four wheels. The ventilation disc has many process holes, a wide range of friction material options, is lightweight but has a relatively high manufacturing process and price. Ventilated discs have better heat dissipation performance and can dissipate heat through holes, thus having a longer service life. During braking, they can quickly dissipate heat and maintain good braking performance. In contrast, so
