Custom Premium Braided Brake Hoses Engineered for Automotive Performance

PTFE liners, reinforced wire braiding and OEM/ODM configurations tailored to your application.

Premium Braided Brake Hose System

Keli provides customizable braided brake hose configurations for automotive brake system projects. Options can be evaluated for hose dimensions, reinforcement construction, liner materials, outer protection, and end fittings according to the specified assembly requirements.

For project evaluation, share your technical drawing, required hose dimensions, brake fluid type, working pressure, and operating temperature.

What Is a Braided Brake Hose?

A braided brake hose is a flexible fluid-carrying hose that uses a reinforced construction to support its intended operating conditions. In a typical design, an inner tube carries brake fluid, a metal braid provides reinforcement, and an optional outer jacket protects the assembly from external exposure.

The complete hose must be selected according to its intended brake fluid, working pressure, temperature range, routing conditions, and connection requirements. The suitability of each material and construction should be confirmed against the applicable product specification.

Premium Braided Brake Hose System Structural Characteristics

Outer Jacket

Smooth gray polymer jacket, allowing for fast threading and routing in cable assemblies.

Reinforcement Layer

Internally bonded with a high-strength wire mesh, forming a robust annular support skeleton that effectively resists external pressure.

Key Performance Characteristics

  • Pressure Performance: Verify the hose’s rated working pressure and applicable test requirements for the intended application.
  • Fluid Compatibility: Confirm compatibility between the selected inner tube and the specified brake fluid under the relevant operating conditions.
  • Temperature Range: Define the required continuous and peak operating temperatures and verify the suitability of the complete hose construction.
  • Flexibility and Routing: Check whether the hose can accommodate the required installation path without violating the manufacturer’s bend or routing limitations.
  • External Protection: Evaluate the need for abrasion, moisture, corrosion, or other environmental protection based on the installation conditions.
  • Dimensional Consistency: Confirm the required inner diameter, outer diameter, length, and assembly dimensions against the approved drawing.

Brake Fluid Compatibility

Brake fluid compatibility must be confirmed for the complete hose assembly, not just the inner tube material. The selected liner, reinforcement construction, outer protection, seals, and end fittings should be reviewed against the specified fluid and operating conditions.

For an OEM project, please provide:

  • The specified brake fluid type
  • Required working pressure and temperature range
  • Hose dimensions and routing conditions
  • End-fitting and connection requirements
  • Any applicable product or validation standards

Material options can then be reviewed against the project requirements. Compatibility claims should be confirmed through applicable technical documentation and validation testing.

Flexible OEM/ODM Customization & Supply Chain Support

Keli supports OEM/ODM projects with supply options tailored to the customer’s production and assembly requirements.

Precise dimensional matching

Standard specifications are supported; hose lengths can be cut per drawings with tolerances tightly controlled to the millimeter level.

Appearance & brand coding

Customizable jacket colors (transparent, semi-transparent, solid colors) and silk‑screen printing on the hose body (brand logo, specifications, production batch) are supported, helping your product establish a distinctive visual identity.

Flexible supply

Depending on your production model, we can supply bulk hose coils for your own crimping, or provide fully crimped hose assemblies according to your drawings.

Rigorous Quality Control System (Quality Assurance)

100% air tightness & pressure test

Every finished assembly undergoes a 100% pneumatic leak and pressure test before shipment.

Extreme testing

Regular random samples are subjected to high‑low temperature pulse fatigue tests, salt spray corrosion tests, and fitting pull‑off strength tests, ensuring that all data fully comply with the stringent standards of the automotive hose industry.

Fluid compatibility

Both the inner tube and the fluoroplastic outer jacket exhibit excellent chemical inertness towards DOT3, DOT4, and DOT5.1 brake fluids, with no swelling or leaching even after prolonged exposure.

Custom Premium Braided Brake Hose System & OEM/ODM Solutions

Keli can review project-specific hose configurations based on the technical requirements of the complete brake hose assembly.

Customization parameters for evaluation may include:

  • Hose Dimensions: Inner diameter, outer diameter, wall thickness, and required length.
  • Liner and Outer Protection: Material options subject to fluid compatibility and operating requirements.
  • Reinforcement Construction: Wire material, wire dimensions, and braid configuration.
  • End Fittings: Fitting type, connection interface, orientation, and assembly dimensions.
  • Product Identification: Marking and packaging details defined by the approved project specification.

To begin a technical review, provide an engineering drawing, sample, or dimensional specification together with the intended brake fluid, operating pressure, and temperature range. Final configurations depend on technical feasibility and validation requirements.

Premium Braided Brake Hose System Manufacturing & Quality Control

Manufacturing controls are applied at relevant stages of production to help ensure that the finished hose matches the approved specification.

  • Material Preparation
    Incoming materials are reviewed against the applicable material and purchasing requirements.
  • Hose Formation and Reinforcement
    The inner tube and reinforcement are prepared according to the specified construction. The process parameters depend on the selected hose design.
  • Outer Protection and Finishing
    Where specified, an outer jacket is applied and the hose is finished to the required dimensions and appearance.
  • Assembly and Final Inspection
    For finished hose assemblies, the hose, end fittings, connection orientation, and relevant assembly dimensions are checked against the approved drawing and inspection requirements.

The production route and inspection plan may vary according to the product configuration. Applicable checks and acceptance criteria should be documented in the product-specific quality requirements.

How to Choose the Right Premium Braided Brake Hose

Selecting a braided brake hose requires confirming the requirements of the complete brake system and hose assembly.

  • Confirm the Brake Fluid
    Identify the specified brake fluid and verify compatibility with the complete hose assembly, including the liner, seals, and fittings.
  • Define the Pressure and Temperature Requirements
    Specify the required working pressure, relevant pressure peaks, continuous operating temperature, and any applicable validation requirements.
  • Confirm Hose Dimensions and Routing
    Provide the required inner diameter, outer diameter, length, installation path, and any relevant routing constraints.
  • Specify the End Fittings
    For a finished assembly, identify the fitting type, connection interface, orientation, and assembly dimensions using a drawing or approved specification.
  • Confirm Testing and Documentation
    Define the applicable test methods, acceptance criteria, product identification, and required quality documentation before production.

For OEM projects, provide the available technical drawing and application requirements so the proposed configuration can be reviewed against the intended use.
