Automobile brake hose (commonly known as brake pipe) is a component used in automobile brake system. Its main function is to transmit the brake medium in automobile braking to ensure that the braking force is transmitted to the automobile brake shoe or brake caliper. Generate braking force, so that braking is effective at any time. The hydraulic brake hose assembly kits consists of a brake hose and a brake hose joint. There is a permanent connection between the brake hose and the brake hose joint, and the connection is realized by crumpling or cold extrusion of the joint relative to the hose.
