Problems solved by technology
[0002] The bicycle brake system includes accessories such as brake handles, brake lines, and brake calipers. The brake system of the prior art is usually provided with two brake lines, one front and one rear, and two corresponding brake handles and two brake calipers. Brake wires tend to break after being used for a period of time, causing brake failure and high potential safety hazards. In order to solve the above technical problems, it is necessary to use a two-wire brake system with two front brake wires and two rear brake wires. The two brake wires of this brake system The length of the two front brake cables needs to be the same to ensure that the two brake cable bodies are evenly stressed during braking, but the two independent brake cable bodies cannot guarantee the same length, and there are certain difficulties in assembly
[0003] At the same time, the existing brake line body is composed of an external rubber hollow tube and an internal steel wire, which has insufficient strength, poor chemical corrosion resistance, poor weather resistance, and high production cost; the end of the existing brake line is A hook is used to fix the handle. After a long time of use, the hook will be deformed, which will cause the brake line to be disconnected from the handle, so that the brake will fail and accidents will easily occur

The invention relates to a brake cable which comprises an outer wrapping layer (1), two parallel lining pipes (2) and two wound springs (3); each brake cable body (4) comprises an inner carbon fiber core wire set (4.1) and an outer resin layer (4.2); an annular belt (5) is arranged at the end part of the brake cable body (4). According to the high-strength brake cable, two brake cable bodies are uniformly stressed and are easy to form, light in weight, resistant to chemical corrosion, good in weather resistance and low in production cost; the annular belt is arranged at the end part of the brake cable body and used for fixing the brake cable with a handle, so that the brake cable cannot be separated from the handle and the driving safety is guaranteed.
