This includes the brake line, which is flexibly connected to the brake by a brake hose, and the brake hose is generally fixed to the car with a fixed bracket. During the driving process of the car, the brake hose fixed to the car body by a fixed bracket will move appropriately according to the road conditions. During movement, the movement trajectory of each part of the brake hose is difficult to control, especially when the brake hose needs to pass through a small space, the brake hose is easy to interfere with surrounding parts, thereby affecting the safe driving of the car and causing potential harm to traffic safety.

[0003] Automobile brake hose is a component used in automobile brake system. Its main function is to transfer brake medium during automobile braking, ensuring that the braking force is transmitted to the automobile brake shoe or brake caliper to generate braking force, so that the brake is effective at any time.

[0004] The existing rear brake hose has many peripheral parts, which is easy to swing during driving and interfere with the peripheral parts, causing wear of the brake hose and accidents.
