What is automotive vacuum brake hose
Automotive vacuum brake hose is an important part of automotive brake system, mainly used in the braking process to provide necessary vacuum power.
Definition and function
Automotive vacuum brake hose is a kind of hose in the brake system, which is mainly used to transmit vacuum power to help the driver step on the brake pedal more easily, thereby shortening the braking distance and improving driving safety. By connecting the vacuum booster pump and the brake master pump, it uses the vacuum booster to amplify the brake force and make the brake more sensitive .
Structural characteristics
Automotive vacuum brake hoses are usually composed of inner and outer rubber layers and chemical fiber braided reinforcement layers. The inner layer transmits the vacuum, while the outer layer provides protection and support. This design allows the hose to maintain stable working performance under different driving conditions, while having good durability and aging resistance .
Care and maintenance
It is very important to check the condition of the vacuum brake hose regularly. Check hoses for aging, cracks, or wear, and joints for looseness or leakage. If any problem is found, it should be replaced in time to avoid failure of the brake system. In addition, keeping the surface of the hose clean and preventing corrosion and contamination is also the key to extending its service life .
The main function of automotive vacuum brake hose is to provide help for the brake, enhance the handling performance of the car, and ensure the normal work of the vacuum tube, so as to ensure that the car can obtain a certain braking force . Specifically, the brake vacuum hose provides a vacuum degree for one side of the working pump film, and the other side is communicated with the atmosphere, plays a helping role, drives the push rod to move forward, and thus provides the brake power .
In addition, the automotive vacuum brake hose is also divided into two types: one is used for the brake booster pump, the other is used for the distributor ignition advance device. Their main function is to provide a vacuum environment for one side of the working pump film, while the other side is communicated with the atmosphere .
In terms of installation and maintenance, brake tubes need to be replaced to ensure that they are not twisted or bent and do not rub against other parts. Avoid any twists during installation, as this may cause the hose to fail prematurely. At the same time, make sure the brake joint is tight enough to prevent leaks, but not too tight. In addition, brake fluid can corrode painted surfaces, so care needs to be taken to prevent any leaks and to wash areas in contact with the body immediately .
