Product Introduction

The rubber brake hydraulic hose assembly is a critical component in the automotive hydraulic braking system. It consists of a rubber brake hydraulic hose combined with metal fittings (or other connecting parts) at both ends, designed to reliably transmit brake fluid pressure during the braking process and ensure the proper functioning of the braking system. The following sections provide a detailed overview from the perspectives of structure, function, performance requirements, and applications.

Structural Composition

The core of the rubber brake hydraulic hose assembly consists of two parts, which are firmly joined together through a specific manufacturing process.

Rubber Brake Hydraulic Hose

The flexible body of the assembly, typically composed of multiple layers including an inner rubber layer, a reinforcing layer (such as a braided layer), and an outer rubber layer (for details, refer to the structural description of "Rubber Hydraulic Brake Hoses" mentioned earlier), serves the functions of transmitting brake fluid and accommodating vehicle movements.

Metal Connector

It serves as the interface connecting the hose to other components of the braking system, such as the master cylinder, wheel cylinders, and rigid pipes. The material is typically made of brass, carbon steel, or stainless steel, with surfaces often treated via plating processes like galvanization or chrome plating to enhance corrosion resistance. The design of the connector type varies depending on the vehicle model and installation requirements, commonly including tower-style, flange-style, and threaded designs, all of which must match the corresponding connection ends within the braking system.

The connection process between the two components is critical to the overall assembly quality. Common methods include crimping, vulcanization, or welding, ensuring that there are no leaks between the connector and the hose, while also providing high-pressure resistance and the ability to withstand vibration and impact.

Core Features

Pressure Transmission

When the driver presses the brake pedal, the hydraulic pressure generated by the master cylinder is precisely transmitted through the hose assembly to the wheel cylinders, actuating the brake pads/shoes to make contact with the brake discs/drums, thereby achieving vehicle braking.

Flexible Connection

During vehicle operation, components such as the suspension and body experience relative motion. The flexibility of the hose assembly effectively compensates for these displacements, preventing damage to the braking system caused by rigid connections while ensuring uninterrupted pressure transmission.

Sealed protection

The tight connection between the metal fitting and the hose prevents brake fluid leakage, while the sealing performance of the outer rubber layer and the fitting safeguards the internal brake fluid from contamination by external impurities such as dust and moisture.
