Product Introduction:

This type of brake disc is drilled and marked line scottled on the surface of ordinary brake discs. The purpose of this treatment is to improve the cooling performance of the brake disc and quickly dissipate heat. Reduce its thermal decay and provide better braking capabilities.

Product Advantage:

We are a professional manufacturer and processor of automotive passanger cars brake discs with over 20 years of production technology experience. Our products exported to various parts of the world, covering various models and brands of Japanese, Korean, German, American, Chinese, and Russian: BMW, BENZ, VW, FORD, TOYOTA, HONDA, NISSAN, MAZDA, JEEP, RANGE ROVER, HUNDAI, KIA, LADA, PEGUOT, HAVAL, BYD, CHERY, GEATWALL, HAVAL, GEELY, CHANGAN, JAC, JMC.....

There are over 10000 models of brake systems discs and brake plate that are constantly increasing with market changes.

Our brake rotors adopt advanced high-tech technology from casting to CNC lathe processing to packaging, with dynamic balance detection to ensure smooth and fast braking during the driving process of the car.

Our company can accept large quantities of containers and small batches of orders, with varying quantities and engraving and labeling processing according to customer requirements. Accept sample processing and drawing processing. At the same time, it can also accept deep processing and modification processing of brake discs. For example, the brake rotor accessories is painted with colors, galvanized, Dacromet, drilled, and the surface of the marking lamp is decorated and processed.

Product uses:

The brake disc is definitely used for braking, and its braking force comes from the brake caliper. Generally speaking, the brake caliper is fixed on the part where the inner brake piston pump is located, and the outer side is a caliper like structure. The inner brake pad is fixed on the piston pump, and the outer brake pad is fixed on the outer part of the caliper. The piston pushes the inner brake pad through the pressure from the brake oil pipe, and at the same time, the caliper is pulled by the reaction force, Make the outer brake pads inward. Both are simultaneously pressed against the brake disc, generating braking force through the friction between the brake disc and the inner and outer brake pads. During this process, the piston is pushed by brake fluid, which is hydraulic oil. This is assisted by the engine

For hand brakes, a cable is used through a lever structure mechanism to forcefully pull the brake pads, causing them to press tightly against the brake disc, thereby generating braking force.
