What is the rear brake hose of a car
The rear brake hose is an important component of the automotive braking system. Its main function is to transfer the brake medium during braking, ensuring that the braking force can be effectively transmitted to the brake shoes or brake calipers of the vehicle, thereby achieving braking effect .
Classification and material
Automobile brake hoses can be classified into the following types based on different braking methods:
Youdaoplaceholder0 Hydraulic brake hose : mainly used in hydraulic brake systems.
Youdaoplaceholder0 Pneumatic brake hose : For pneumatic brake systems.
Youdaoplaceholder0 Vacuum brake hose : For vacuum brake systems .
In addition, brake hoses can also be classified according to their materials as:
Youdaoplaceholder0 Rubber brake hose : Strong tensile strength, easy to install, but the surface is prone to aging .
Youdaoplaceholder0 Nylon brake hose : Strong oxidation resistance and corrosion resistance, but tensile strength weakens at low temperatures and it is prone to breakage .
Maintenance and upkeep
To ensure driving safety, car owners need to regularly inspect and maintain brake hoses. Specific measures include:
Youdaoplaceholder0 Regularly check the surface condition of the brake hoses to prevent corrosion and wear.
Youdaoplaceholder0 Check if the joint is loose or not sealed properly Make sure there is no oil leakage.
Youdaoplaceholder0 Replace aged brake hoses in time to avoid affecting braking performance due to aging, poor sealing or scratches .
Regular inspection and maintenance of brake hoses can ensure the normal operation of the car's braking system and guarantee driving safety.
The main function of the rear brake hose is to transfer the brake medium during the braking process of the vehicle to ensure that the braking force can be effectively transmitted to the brake shoes or brake calipers so that the vehicle can effectively brake .
Specifically, the brake hose plays a crucial role in the automotive braking system. It forms a closed hydraulic transmission channel that transmits the hydraulic pressure generated when the driver pedals to the brake calipers or brake shoes of each wheel without damage .
The design and material selection of brake hoses are also very important. It usually adopts a multi-layer structure, including an inner rubber layer, a reinforcing layer (such as nylon or steel wire braided), an insulating layer and an outer protective layer. This design makes the brake hose both flexible to accommodate displacement while the vehicle is moving and pressure-resistant to withstand pressure pulse test standard above 35MPa .
In addition, brake hoses need to withstand high temperatures (instantaneous high temperatures above 300 ° C generated by friction during braking), oil resistance (compatible with DOT3/DOT4 brake fluid), and deformation resistance .
To ensure the normal operation and service life of brake hoses, regular inspection and maintenance are necessary. Brake hoses may lose their elasticity due to wear, aging or cracking during long-term use, resulting in a decline in braking performance and even potential safety hazards. Therefore, it is recommended to replace every 30,000 kilometers or so to ensure the stability and safety of the braking system . In addition, routine maintenance includes regular inspection of the surface of the hose for cleanliness, avoiding pulling the hose forcefully, and checking for loose or poorly sealed hose couplings .
Youdaoplaceholder0 The main causes of rear brake hose failure include rubber aging, bumps and scratches on the hose body, quality problems . These faults can cause problems such as cracking, leaking, bursting, scratching and scratching of the tube, which in turn affect braking force and braking performance, and may even cause braking failure, threatening driving safety .
Fault manifestation
Youdaoplaceholder0 Tube cracking : Aging of rubber leads to poor compressive performance, making it prone to cracking and leakage.
Youdaoplaceholder0 Leaking TUBE : Leaking tube poses a threat to driving safety.
Youdaoplaceholder0 Burst : It is a typical quality problem.
Youdaoplaceholder0 Pipe body scratches and cuts : Prone to occur in bad road conditions or with human damage, poses a significant safety hazard.
Youdaoplaceholder0 Bulge : Similar to a tire bulge.
Youdaoplaceholder0 Rusty joint : In severe cases, the joint may break, causing brake failure .
Impact of malfunction
These faults can cause reduced braking force, affect braking accuracy and reliability, and threaten the lives of drivers and passengers .
Preventive measures and maintenance suggestions
Youdaoplaceholder0 Regular inspection : Check the integrity of the brake hoses frequently and deal with any damage found promptly.
Youdaoplaceholder0 Replacement cycle : Replace immediately after 3 years of use or after 3 years. If cracks, oil leakage, bulges, etc. occur, it is also recommended to replace the brake hose directly .
