Description

brake disc

This creation is related to brake discs.

The braking force is generated through the friction force of the caliper to brake the brake disc to achieve the purpose of braking. The disc can be divided into a fixed disc and a floating disc. The industry has developed a floating disc to solve this problem. A general floating disc includes an inner disc, an outer disc and a floating buckle. The floating buckle is used to connect the inner and outer discs. When the outer disc is squeezed by the caliper, it can be pressed accordingly. A slight offset allows the pads to fully engage for better braking performance.
