Hydraulic brake hose assemblies

Function：

In hydraulic braking systems,brake hoses serve to transmit brake fluid. The brake hoses connect the drive elements, such as the master brake cylinder, to the hydraulic components of the wheel brake. The brake hoses are used in all moving zones between the body and the chassis as flexible connecting elements. Brake and brake hoses are used to carry out the transmission of the brake fluid. 

Due to the integration of ABS, ESP and ASR systems in modern vehicles, the requirements that these systems must meet are increasingly demanding. Among these requirements is resistance to pressure, mechanical loads, as well as good thermal and chemical resistance

The brake hoses are subject to the following influences and loads:

• Mechanical load: movements of articulation and damping of the vehicle
• Climatic influences: Heat, cold and ozone
• External influences: Heat, salts and oil
• Electro-hydraulic pressure pulses: In hydraulic brake systems, short
• pressures of up to 180 bar may arise.
