Product Introduction

Rubber hydraulic brake hoses are critical components connecting various parts of the automotive braking system, primarily used to transmit brake fluid and enable vehicle braking functionality.

Structural Composition

Inner rubber layer: Typically made from ethylene propylene diene monomer (EPDM) rubber, it offers excellent corrosion and oil resistance, ensuring good compatibility with brake fluid while effectively preventing brake fluid leakage.

Braided Layer: Typically made of steel wire or synthetic fiber braiding, such as polyester or nylon, this layer enhances the hose's strength and pressure resistance, enabling it to withstand the high pressures within the braking system.

Middle rubber layer: Located between the two braided layers, its primary function is to bond the braided layers together while enhancing the hose's flexibility and fatigue resistance.

Outer rubber layer: Typically made from EPDM or chloroprene rubber, offering excellent weather resistance, abrasion resistance, and anti-aging properties. It effectively protects the internal structure from external environmental factors such as ultraviolet radiation, rainwater, and oil contamination.

How it works

When the driver presses the brake pedal, the piston inside the master cylinder pushes the brake fluid. This brake fluid is then transmitted through rubber hydraulic brake hoses to the wheel cylinders, which in turn actuate the brake shoes or brake pads, generating the braking effect necessary to slow down or stop the vehicle.

Performance Characteristics

High-pressure resistance: Capable of withstanding high pressures, typically operating at several megapascals or even higher, ensuring the proper functioning of the braking system.

Good flexibility: Features a small bending radius, enabling it to accommodate relative movements between different vehicle components during operation without being easily damaged by bending.

Excellent corrosion resistance: Exhibits outstanding resistance to brake fluid, water, oils, and other media, ensuring that the hose maintains optimal performance over extended use without being compromised by medium-induced erosion.

Excellent anti-aging performance: Features outstanding resistance to aging, ensuring stable performance across varying temperature conditions and delivering an extended service life.

Application Fields

Primarily used in hydraulic braking systems for various motor vehicles, including automobiles, motorcycles, and light-duty trucks, it is an indispensable component of the braking system.
