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 costs.

Abstract
The invention relates to a corrosion-resistant brake cable assembly, which comprises an outer coating layer (1), two liner pipes (2) arranged side by side and two winding springs (3), wherein each brake cable body (4) comprises an inner carbon fiber core wire group (4.1) and an outer corrosion-resistant layer (4.2). The brake cable assembly provided by the invention has the advantages that the lengths of two brake cables are equal is ensured by liner pipes, and that two brake cable bodies receive force uniformly during braking is ensured; the brake cable bodies are simple to form, light, chemical-corrosion-resistant, good in weather resistance and low in production cost.
