Description

Technical Field

[0001] The utility model relates to the technical field of disc brakes, and more specifically, to a bicycle disc brake module. Background Art

[0002] The working principle of the disc brake system is to install a disc that rotates synchronously with the wheel on the hub, and install calipers on the front fork and frame, and then clamp the disc through the brake pads in the caliper to achieve the purpose of braking. At present, disc brakes are mainly used in high-end cars in the market, and have become the standard configuration of high-end cars. Due to the high price and heavy weight of the disc brake system, it cannot be popularized. Compared with traditional V brakes, disc brakes have stronger braking force and more stable performance. This makes them more reliable when riding at high speed or in extreme conditions. Stronger braking also brings higher friction loss. Disc brakes have fast friction loss on the edge of the brake disc, resulting in poor durability. Utility Model Content
